BROWN WILLIAM E. WARNE Adminisfraior Governor Director The Resources Agency of California State of CalJfornia Department of Water Resources FORE\;OKD In 1956, the State Legislature declared "that in providing for the JTull development and utilization of the water resources of this State it is necessary to obtain for consideration by the Legislature and the people, information as to the water which can be made available for export- ation from the watersheds in which it originates without depriving those watersheds of water necessary for beneficial uses therein." The Department of Water Resources was, therefore, authorized and directed to conduct such investigations as necessary to compile this information. To do so, the department began its statewide Inventory of Water Reso;arces and Water Requirements as outlined in the authorizing legislation (Water Code Section 232). For purposes of this inventory, the State has been divided into major hydrographic areas. These areas, in turn, have been subdivided into hydrographic units generally comprising watersheds of individual rivers. Basic data, consisting of land and water use, classification of lands, and streamflow measurements, are collected for each hydrographic •unit. To date, this activity has been concentrated mainly in northern >ra.tersheds. Results of this inventory will be presented in two series of reports covering (l) land and water use, and (2) water resources and water requirements. The data on land and water use, together with land classification,- are being published as the Bulletin ^ series; one for each hydrographic unit. This report covering the Mad River-Redwood Creek Hydrographic Unit is the seventh in the series. As the data relative to particular hydro- graphic units are published they become available for general studies and project investigations, not only by the department, but by all other parties concerned \d.th the watersheds covered. When completed, this series of bulletins vrlll provide detailed data for the whole State. A second series of reports, each covering one or more hydro- graphic units, will include determinations of the available water resources and future requirements of those areas. The water resources will be determined from the records of older stream gaging stations, and a number of new stations, mainly on smaller streams not previously measured. The determination of water req\iirements will be based on land use patterns projected for specific points of time. These projections, in turn, will be based on the land and water use and land classification data, such as contained herein, and other available information. Although the data developed by this inventory are to be lased throughout the department's planning activities, they are most urgently needed for the staging of water projects. For this reason, the develop- ment of these data and their application to the timing of projects were combined in the Water Requirements and Project Staging program in I96I. Under this program, determinations of the quantities of water available, and the time, place, and magnitude of the future water needs of the entire State are combined in the formulation of a sequence of projects to meet those needs. An interim staging report will be published in 1963-614-.

This report, entitled "Land and Water Use in Mad River- Redwood Creek Hydrographic Unit," presents results of studies conducted pursuant to legislation sponsored by Senator Edwin J. Regan and codified under Section 232 of the Water Code. This series, when complete, will form an invaluable reference of the water resources of the State in relation to the various classes and uses of land resources. The data contained in this series of reports provide a basis for estimates of the amount of water which originates within each watershed, the amount which csua be used beneficially within each area, and the amount of surplus or deficiency, therein. These estimates are being included in the staging of projects to develop most efficiently the water resources of the State. The data presented in this bulletin will provide a factual basis for decisions of concerned interests regarding the developnent and use of the water resources of the Mad River-Redwood Creek Hydro- graphic Unit. In addition, the bulletin includes notes on the history, natural features, climate and economy of the unit. All public and private sigencies, local interests, and indivi- d\ials \Aio may be concerned with the information presented herein are invited to submit their comments.

The unit, which is located and outlined on Plate 1, is composed mainly of the watersheds of Mad River ajid Redwood Creek, but also includes the smaller watersheds of Little River, Maple Creek, and a number of lesser streams flowing directly into the Pacific Ocean. The data include descriptions of systems used to divert water from the various streams in the hydrographic unit, together with histories, apparent water rights data, and purpose and extent of use of each diversion. The data also include monthly qviantities of surface water diverted, land use data, and an estimate of total consumptive use of applied water for 1958, and classification of lands in the unit as to suitability for irrigation and for potential recreational development. These data are prefaced by a general description and brief history of the hydrographic unit and immediate vicinity. These basic data were gathered during the period from 1958 to 1959 in compliance with Chapter 6l, Statutes of 1956, as amended by Chapter 2025, Statutes of 1959, and codified in Section 232 of the Water Code of the State of California. This legislation provides for an inventory of water resources and water requirements of the State. This report is the seventh of the series of biilletins to be prepared under this authorization. The text of Section 232, with a discussion of its histoiy and implications, is included in this bulletin as Appendix A. These data will provide the basis for determination of the qioantities of water that are required for jwtential future uses in the hydrographic unit, the extent to which local water supplies will meet such requirements, and the amounts of water ■vrtiich will be available for export -1- from the various watersheds of the unit. These future determinations will be based on estimates of: (l) projected land use patterns, (2) economic patterns, (3) population, (k) industrial and agricultxiral development, and (5) recreational needs. All the investigational work and findings accomplished under the inventory of water resources and water requirements legislation have been and will continue to be closely coordinated with other activities of the Department of Water Resources, the U. S. Bureau of Reclamation, the U. S. Corps of Engineers, axid local water agencies. A major project formulation study program being conducted by the department which pertains directly to the area covered by this report, and which will utilize basic data presented herein, is the North Coastal Area Investigation. This is a comprehensive investigation directed toward the formulation of plans for future water resources projects within the large drainage basins of the Worth Coastal region from the Russian River on the south to the Smith River on the north. The fundamental objective of this continuing program is the delineation of plans denoting the probable econom- ically optimum development sequence for staged major water resources project units. In implementation of the California Water Resources Development Act of 1959, the department is required to provide such additional facilities as may be required to meet contractual obligations. These additional conser- vation facilities will provide for the augmentation of the water supplies to be made available by the State Water Resources Development System as future depletions occur and as future demands increase. Current studies, as well as previous studies made for The California Water Plan, indicate that the rivers of the North Coastal area will best provide these additional large -2- supplies. These projects will be designed to meet futxxre demands for nev water service in both local aind water deficient areas of the State. Under the multipurpose concept, concurrent consideration is given to protection against recurring floods, developnent of hydroelectric power ajid water- associated recreational potential, the preservation eind possible enhance- ment of anadromous fisheries, and to a limited extent of water- oriented land management. As listed in Appendix B of this bulletin, a progress report on the North Coastal Area Investigation was published in May I961. Certain of the data presented in this bulletin have been reviewed in preliminary form by officials of Humboldt and Trinity Counties and by local water users. Since its organization, the Humboldt County Water Study Committee has been kept informed of the progress and findings of the investi- gation for this bulletin. Organization of Report This bul 1 etin is essentially a compilation of basic data on land use, water use, and land classification, in the form of tables and plates with supplemental explanatory text, and three appendixes containing relevant supplementary data. Chapter I contains a general description of the history, economy, and natural features of the Mad River- Redwood Creek Hydrographic Unit. Plate 1, prepared m connection with Chapter I, shows the location of the hydrographic unit and of the subunits into which it is divided. Chapter II presents data on surface water diversion systems, including descriptive, historical, water rights ajid water use data; measurements of quantities of water diverted; and a summary of consumptive use. Chapter III describes the history of land use within the unit, and sets forth in tables the results of a survey of present land use. The 11 sheets of Plate 2, consisting of -3- maps prepared in connection with Chapters II and III, delineate the loca- tions of diversion systems emd the areas of various 1958 land vises. Chapter IV includes a tabulation of lands classified with regard to their potential for irrigated agriculture and for recreational purposes. The 11 sheets of Plate 3, consisting of maps prepared for this chapter, delineate the respective classes of land grouped into several major cate- gories. Chapter V stimmarizes the data presented in the report. Appendix A presents the text of Section 232 of the California Water Code ajid a discussion of the pertinent responsibilities and work program of the Department of Water Resources. Appendix B is a bibliography of publications pertinent to the hydrographic imit. Appendix C presents a short sxammary of California Water Law and a tabulation of applications to appropriate water in the unit. General Description of Area The Mad River-Redwood Creek Hydrographic Unit is a narrow land area approximately 90 miles long, with a maximum width of 20 miles emd a mlnirnxm width of less than 5 miles. The total area of the \mlt is 929 square miles, of which 770 square miles lie within Hiimboldt County and 159 square miles lie within Trinity County. The exterior limits of the drainage basins of the Mad River eind Redwood Creek virtually delineate the boundaries of the \inlt. The unit is bordered by the watersheds of the Klamath and Trinity Rivers on the north and east, and those of the Eel and Van Duzen Rivers and Humboldt Bay on the south. The unit boundary representing the southern limit of the Jfe,d River watershed on the coastal plain north of Areata, appearing on Sheet 5 of Plate 2 and Plate 3, is located along the apparent drainage line as indicated by the topography shown on the U. S. Geological Survey -4- Eureka quadraxigle map, dated 1951 > an<3- does not necessarily coincide with delineations vised in other studies covering this area. For purposes of convenience and utility in reporting data, the unit has been subdivided into nine subunits. General locations of these subuxdts and that of the unit itself are shown on Plate 1. The area of each, by counties as well as by total, is listed in Table 1. Historical and Present Development The historical and present development of the Mad River-Redwood Creek Hydrographic Unit cannot be properly disciissed without the concurrent consideration of the development of the entire Eureka euid Humboldt Bay area. The history of this area, comprising all of Humboldt Coiinty and western Trinity Cottnty, has been greatly affected by its geographical feat\ires. At the beginning, because of the inland mountains, the two available anchorages, Trinidad and Humboldt Bays, were virtually the only routes of access. Because of its greater size euad protection as a harbor, and the surrounding area suitable for continued growth, Humboldt Bay soon became the hub of activity. Near its shores, in Eureka emd vicin- ity, the great bulk of the district's population, business, and indiistry has developed. The two largest communities within the bovindeiries of the Mad River- Redwood Creek Hydrographic Unit, Blue Lake and the xmincorporated community of McKinleyville , are, in fact, extensions of the Humboldt Bay- Eureka development. Before the coming of the white man, this area was inhabited by Indians. The tribes within the boundaries of the Mad River-Redwood Creek Hydrographic Unit were the Wiyots in the area of the lower Mad River, the Chilulas within the area of lower Redwood Creek, and the Whilkits within the area of the upper Mad River and upper Redwood Creek. •5- E^ H CO H CQ -P -P -P ■P H -P o g -9 3 w -p I" I t~- J- L/\ O VO c- o CO MD LTN -d- -d- H CM o\ CO COI ON ^ MDI CM H CA VO H -4- H ON LTN o H ^ ITN J- VO r- VO CM ^ J- CT\ CO VO o o O O o O o o O R o f- CM H oo VO ro Lf\ ITN H CT) O ON o CM o\ CM m CM -* •% •v •\ •\ •v •v •\ •* •* •» CO J- H o C7\ a\ M3 H CO ^ V£> Lr\ 3 VO CM CM tr- ON ■^ H LTN 8.

The adjacent Pacific Ocean provided the means for the white man's discovery of the Humboldt region. The first recorded activity in the area of the Northern California coast was that of the Spanish explorers Juan Rodriges Cabrlllo and Baortolome Ferrelo, in I5U2 and 15^3- These men explored the area immediately to the south of, but did not actually dis- cover, the Humboldt region itself. Probably the first European explorer to discover the Humboldt region was the famous Sir Francis Drake, in about 1580. In 1775^ the Spanish explorers, Jxian Francisco de la Bodega and Br\ino de Heceta, discovered Trinidad Bay, located at the southern tip of the Big Lagoon Subunit of the Mad River- Redwood Creek Hydrographic Unit. In 1806, Captain Jonathan Winship entered Hvimboldt Bay, which was later to become the most importajit center of a.11 development in the entire area. During the time of Captain Winship, the only economic activities in the area were carried on by fur traders of various nationalities. The discovery of gold in 18^-8 on the upper Trinity River was a keypoint in the history of Northwestern CaJLifomia. The development of mining in the Trinity region brought about the establishment of supply routes between the mining region and the Humboldt Bay area. The desire to establish a supply route to the Trinity mines brought about intensive exploration of the Humboldt coastal area. One of the more important expeditions of the day was that led by Dr. Josiah Gregg in l8i)-9 and I85O. Dr. Gregg's party explored the vicinities of Humboldt Bay, the Mad River, Big Lagoon, Little River, and the Eel River. Lack of harmony existed between Dr. Gregg and other members of the party; Dr. Gregg himself was said to have had a bad temper. One day when Dr. Gregg was siirveying near the mouth of a river, he spied other members of his party in canoes well out into the stream. Thinking that his party was deserting him. Dr. Gregg made a q\iick dash for the nearest canoe by wading ■8- deep into the cold water. The thorough soaking of himself and his instru- ments gave strong rise to Dr. Gregg's temper. As a result, the other members of the party were subjected to a violent battery of abusive language. One of the members later wrote, "In commeration of this we gave the river a name . " Thus the Mad River received its name . Early Develogment . The year I85O marks the beginning of the permanent settlements in the region, and several towns came into being in that year. These settlements were the Trinidad Bay settlement; Union Town, later named Areata; Eureka, the last of the group to be established but -later to become the economic center of the entire region; and Bucksport, immediately south of Eureka. Humboldt City, also situated south of Eureka, was rather short-lived. Union Town was the economic center for the period I85O-I856. The only one of these communities which is actually within the Mad River- Redwood Creek Hydrographic Unit is Trinidad. In 1851 Trinity County, including present Humboldt County, was organized, with Weavervi lie winning out as county seat. In I853 the State Legislature divided Trinity County into two parts, designating the western portion as Humboldt County. Union Town, or Union as it was more commonly called, won the first election as county seat. However, Eureka was coming into some prominence, and competition between the two towns was intense. Following a series of contested elections. Eureka finally was designated by the State Legislature as county seat in 1Q^6. This ensured Eureka's future. At the time of the establishment of these early settlements, the principal contribution to the economy of the region was the packing trade to the Trinity area mines. Whale, shark, and salmon fisheries were flourish- ing. In I85I+, flour and grist mills came into existence. In I856 it is recorded that the first McCormick reaper was placed in operation. This was -9- in the Hoopa Valley area on the Trinity River. Most important of all, however, was the establishment and rapid growth of the l\jmber industry in the early l850's, mainly around Humboldt Bay. This was the start of the most important industry of the Humboldt region. Resources and Industries . The forest products industry is the backbone of the economy of the hydrographic unit. Seventy-nine percent of the unit's gross area is covered with dense stands of redwood, Douglas fir, pine, and other commercial conifers. The standing timber is estimated to be 20 billion board feet. Lumber production in the Humboldt Bay area expanded rapidly after the first mill started in I85O, and it has been reported that by 185^ nine sawmills were operating in the area. These mills were mostly in the Exireka area outside the boundaries of the Mad River- Redwood Creek Hydrographic Unit. Probably the first sawmill within the unit was that operated by Baron Kaxl Von Loeffelholz from about I85O to I856, near Trinidad, The succeeding years brought additional mills to various other parts of the unit. The sales of wood products within the boundaries of the unit reached a peak value of 33 million dollars in 1955- A few years later sales value of wood products stabilized at about 29 million dollars per yeajr. Population growth within the Mad River-Redwood Creek Hydrographic Unit has closely reflected the vicissitudes of the timber industry. This growth was slow and somewhat spasmodic for a long period; but since 1950^ there has been a sharp increase, principally in the Humboldt coast portion. The population was about 8,100 in 1950, and had almost doubled by 196O. The present population of the vinit is slightly over l6,000 per- sons. The population centers are confined to the coastal plains and small valleys, where nearly all the sawmills and intensive farming are located. Developed areas away from the coast are small and scattered. -10- The major agricultural commodities produced presently are dairy products, horticultural products, and range livestock. The first two of these are produced mainly along the coast. The total production, and consequently the relative importance, of horticiiltural products — lilies and cut flowers — has developed rapidly since 19^0. In recent years, the total -value of farm products has been around $2,500,000 per year. In earlier history the port of Trinidad was quite important in commercial fishing activities. It is still of some importance, but now handles only about one-tenth of these activities in Humboldt County; the greater part of this industry in the region now being centered at Eureka, outside the hydrographic unit. Mineral resources axe of a limited natvire, with the exception of huge aggregate reserves and small commercial manganese ore deposits. Most of the output of sand and gravel in Humboldt County comes from within the unit area along the lower reaches of the Mad River. The manganese ore bodies are located in the upper Mad Fliver Basin, primarily in Trinity County. An increasingly important business, and potentially one of the greatest resources, is the recreationsil activity within the unit. Present recreational activity is mostly confined to the state paxks along the coast. However, the rugged back covintry will become more and more important with the construction of additional developnent reservoirs, such as Ruth Reservoir. Water developnent projects within the unit are the 3^000-acre-foot Sweasey Dam and Reservoir on the lower Mad River, and the newly constructed 52,000-acre-foot Ruth Dam and Reservoir on the upper Mad River. The first provides the water supply for the City of Eureka, and the second will supply the larger industrial water users around Humboldt Bay. The water developed from both of these projects is for export to the Eel River Hydrographic Unit. -11- Logs from the unit's forests "^^-^^'^"'- - NATURAL RESOURCES PROVIDE INDUSTRIES Fishing fleet in Trinidad B The remainder of water develoiment activity is confined to relatively small diverters . Natural Features Except for a relatively small coastal plain area and even smaller interior valleys, the terrain of the Mad River-Redwood Creek Hydrographic Unit is composed of steep, and for the most part, inaccessible mo\intains. The maximum elevation of the unit, near the headwaters of the Mad River, is about 5,000 feet. The drainage basins of Mad River on the southwest and Redwood Creek on the northeast form the bulk of the hydrographic unit. The Mad River, starting at its source in southern Trinity County, flows almost directly northwest through western Trinity County ajid across central Hxomboldt County to the Pacific Oceaji. The absence of large tributaries and of main stem forks accounts for the long, narrow drainage basin. The gross area of the basin is approximately 5^0 square miles. Redwood Creek flows from its source in eastern Humboldt County and follows a course roughly parallel to that of Mad River to reach the Pacific Ocean near the northwest corner of the county. This basin is also long and narrow, and it has a gross area of about 285 square miles. The remainder of the hydrographic unit is composed of the drainage basins of smaller streams flowing directly into the Pacific Ocean between the mouths of the Mad River and Redwood Creek. Geology . Rock types which occur in the hydrographic unit are largely sandstone, shale, conglomerate, chert, and greenstone. A large elongated body of mica schist, occurs along the drainage divide between Mad River and Redwood Creek, extending eastward to Redwood Creek in most -13- places. All these rocks are strongly deformed by folding, shearing, and faulting, sjid are generally deeply weathered at the surface. The predorainati northwest drainage pattern is controlled by and aligned with the trends of the principal structural featxires and stratification of the rock iinits. Along the coastal portion of the Mad River drainage are younger sediments, including Cenozoic marine formations, alluvium, dune sands, and terrace deposits. The last three of these form part of a principal ground water basin extending southward into the Eel River Hydrographic Unit. Soils . The soils in this hydrographic unit were formed by two processes: (l) those formed in place on more or less metamorphosed sand- stones, shales, conglomerates or intruded igneoiis rock; and (2) those formed from transported (alluAd.al) soil material originating from these parent rocks. The first group can be f\irther segregated into two categories; those which were formed \mder forest cover, and those formed under grass cover. The soils formed from alluvial material can be segregated as those recently formed which lie along existing streams and rivers ajid those older terrace soils formed from ocean- deposited material. The soils formed in place from consolidated rock under forest cover have a s\arface color ranging from brown to reddish-brown and a sub- soil color of yellow to yellow-brown. For the most part, they are deep and well drained. The grassland soils (also called prairie soils) formed from con- solidated rock are reddish-brown to dark brownish-gray near the surface and yellow to yellowish-brown in the subsoil. They usually are foiind to be shallower than the forest covered soils, and occur on gentle slopes such as roimded hilltops. -11+- The soils formed from recently deposited materials range in color from grayish-brown to brownish- gray, and commonly have medlimi soil texture. Generally, little profile developnent can be seen. In many cases these soils eire subject to frequent flooding or high water table conditions. The coastal plain soils (also called terrace soils) were formed primarily from ocean- deposited soil material that has been uplifted so that the present relief consists of a series of relatively smooth to gently sloping terraces. The soil texture ranges from fine, sandy loam to silty loam. The surface is usually a reddish-brown color with the subsoil yellowish-brown. Drainage is good, althoiigh the subsoil is of a somewhat heavier textiire than the surface. In most cases these soils have, or had at one time, a forest cover. Climate The climate of the Mad River-Redwood Creek Hydrographic Unit varies from the moderate seasons typical of the Northern California coast to the more variable and generally more extreme seasons common to the hi^er in- land areas. In the lower part of the unit, extending some 25 to 30 miles inland, the predominant influence on the climate is the moist marine air mass, which is moved inland by prevailing onshore winds. The overcast or fog generally associated with this air mass has a great moderating effect on the climate of the coastal area. The more inland part of the unit is enough removed from the oceanic inl'luence, both by elevation and by intervening ridges, to be comparatively free of the moderating effect of the marine air mass. This inland area is subject to a wider range of temperature variation, both daily and seasonal, and a more variable distri- bution of precipitation than the coastal area. -15- Average annual precipitation within the unit varies from about l»-0 inches per year near the mouth of the Mad River to about 90 inches per year in the vicinity of Board Camp Mountain. Over 80 percent of the season's, precipitation occurs between November 1 and April 30. In the coastal area, there is generally a measurable amount of precipitation in every month of the year. In the inland part, precipitation usually occ\irs in ^."11 months except J\ily or Aiigust, which often have no measurable rainfall. Average snowfall within the unit varies from a negligible amount along the coast to over k feet per year at Mad River Ranger Station. The average lowest elevation at which there is snow on the ground on April 1 is about i<-,000 feet Maximuxfl and minimum recorded seasonal precipitation and estimates of 50-year mean seasonal precipitation at selected stations within or adjacent to the Mad River-Redwood Creek Hydrographic Unit are shown in Table 2. The extremes shown are the highest and lowest seasonal precipi- tation observed during the period of record indicated for each station. Except for the recorded quantity shown for the Eureka Weather Bureau Station, the 50-year mean seasonal values are estimates of the average depth of rainfall which would have been observed at these stations if they had been in existence during the base period 1905-O6 to 195^-55* It is considered that these mean values are representative of the long-term mean seasonal precipitation of the unit. The climate of the unit is generally illustrated by the temper- ature data presented in Table 3. These data, with the exception of the frost-free period values, were taken from the "Climatic Summary of the United States -- Supplement for I93I through 1952," Bulletin W, published by the U. S. Weather Bureau. The values for the frost-free period were derived by the Department of Water Reso\irces, and represent the average -16- TABLE 2 RECORDED EXTREME AND ESTIMATED MEAN AJWIUAL PRECIPITATION AT SELECTED STATIONS IN OR NEAR MAD RIVER- REDWOOD CREEK HYDROGRAPHIC UNIT (in inches) : Elevation : Annual precipitat Lon : Recorded Recorded : Estimated : Years of Station : (in feet) : raaLximura minimum : 50-year mean : record : used Alderpoint ^35 80.38 (1957-58) 33.84 {1'^3-hk) i+7.07 19^1 - i960 China KLat 650 71.32 (1926-27) 22.55 (l923-2i+) U6.I5 1909 - I95J+ Crannell 150 77.51 (1937-38) 29.69 (1933- 3^+) 51.96 1933 - 19*^8 Eureka h3 7^.10 (1889-90) 20.72 (I923-2U) 36.66 1879 - i960 Forest Glen 2,3i^0 102.1^6 (1957-58) 36.59 (1930-31) 57.73 1930 - i960 Korbel 180 79.96 (1937-38) 36.18 (19^^6-1.7) 51.50 1937 - i960 Ivlad River Ranger Station 2,775 97.81 (1957-58) 39.35 (195I+-55) 55.15 191^ - i960 Orick - Prairie Creek Park 161 92.88 (1955-56) i^6.33 (19^^6-1+7) 65 M 1937 - i960 ■17- period between the last day in spring emd the first day in the fall when the daily minimum temperature fell to or below 32 degrees Fahrenheit.

Water Resources 3 With the drainage basins of I^d River and Redwood Creek comprising the bulk of the hydrographic unit, the runoff records for these streams pro- vide the basis for a general picture of the unit's s\irface water supply. There is a gaging station on the lower reaches of each of these streams. The periods of record are relatively short but sxifficiently long to present an indication of the supply. A summary of data from these two stations is given in Table k. For the period June 1 through September 30, 1958, the observed runoff at the Mad River station was 96 percent of the average, and that at the Redwood Creek station, 77 percent. -18- TABLE k SUMMARY OF RUWOFF MTA I4AD RIVER AND REDWOOD CREEK Item Drainage area: (in square miles) Years of record Mad River near Areata Redwood Creek at Orick 1+85 13 278 9 Runoff : (in acre-feet) Seasonal Monthly Discharge : (in cubic feet per second) Average \ I>l£Lximum Minimum | Ave rage \ Maximum \ Minimum 1,1^0,000 1,721,000 682,900 77U,600 l,17lf,000 533,200 95,000 57!+, 000 1,080 6i+,500 371,^00 972 1,575 77,800 16 1,070 50,000 10 Local Public Agencies Concerned with V/ater Development A number of local public agencies are engaged in vater development or related fields within the r-fed RLver-Redwood Creek Hydrographic Unit. Most of these are water service agencies ort?;anized to serve domestic and industrial consumers. Among these are three incorporated cities: Blue Leuke and Trinidad within the \init; and Eureka, located in the Eel River Hydrographic Unit. The water for these three cities ' systems is supplied from surface diversions within the unit. The largest water development agency in and adjacent to the unit is the Humboldt Bay Municipal Water District, which Includes portions of both the Eel River and Mad River-Redwood Creek Hydrographic Units. The district ' s Ruth Dam had not been built in 1958 when diversion data were collected for this report, and hence it is not included. -19- In addition to these crater se2rvice agencies, both Humboldt ajid Trinity Counties, as members of the Eel River ELood Control and Water Conservation Association, participate in the study of water problems of the general area. Humboldt County, acting principally through its Water Study Committee, is particularly concerned with studies directly pertaining to this unit. • 20- CHAPTER II. WATER USE Present -v/ater requirements of the Mad River-Redwood Creek Hydrographic Unit are supplied aoout ^i-Q percent by diversion of surface runoff, and about 60 percent by pumping of groiind water. For this investigation a survey was made of the diversion and use of the water from surface sources. Survey data reported herein include the location and descriptions of diversion systems, their histories, the uses served by them, and the apparent water rights on which they are based. The criterion for incltision of individual diversions in this report is whether they apparently divert 10 acre-feet or more per year, regardless of the purpose served. Small diversions omitted on this basis were mainly ones which serve only one or a few domestic users. Quantities of water diverted were measured, where feasible, to provide additional basic data concerning water use which will be helpful in determining water requirements of the unit. A total of 68 diversions were studied, of which 65 were active in 1958; a-nd the quantities diverted at kO of these 65 were measured. A summary of the diversions classified as to pur- poses served is given in Table 5- The measured quantities do not necessarily represent average annual quantities for the respective diversions. Rainfall in the unit in 195^ was above normal throu^ April and about normal thereafter. Causes other than weather and runoff conditions, such as economic factors, may also affect the dejree to which diversion records represent typical yearly operating practices. Assessment of these factors is beyond the scope of this report. It appears unlikely, however, that water use in the \init was signifi- cantly above or below normal. The diversion q\iantities reported herein generally represent the actual amounts of irater taken from the sources, and therefore include recoverable and irrecoverable losses incidental to the water use. -21- TABLE 5 SUMMARY OF USE AITO I-IEASUREMENT OF SURFACE V7ATER DIVERSIONS IN MAD RIVER-REDVroOD CREEK liYDROGRAPHIC UNIT (In 1958) _1 68* Numbers of diversions Measurement of diversions Number of : Quantities of Total n\xmber : Diversions used l>lajor purposes diversions rwater diverted in 1958 measured :(in acre-feet) kk* k2* Irrigation and/ or stockwatering 32 1,3^^1 8 8 Municipal and/ or domestic 2 55 10 10 Industrial 3 197 k 3 Hydroelectric power 2 1^95 _1 65* Recreation and/ or fish cultiire Export to Eureka TOTALS _1 i^O 3,866 5,95^+ * Includes tvo diversions from which some of the water diverted is exported from the unit. HLue Lake, Crannell, Trinidad, and several other small communities within the unit are supplied from s\irface water diversions. The Blue Lake and Trinidad systems are municipally owned. Water is also exported from the unit for the City of Eureka from its Sweasey Dam diversion on Mad River. All of the municipal diversions, as we3J. as those for other purposes in existence in 1958, are included in the tabulations in this chapter. Since a sufficiently accurate estimate of ground water use may be made from unit water use requirements and complete land use data, it was not considered justifiable in this investigation to locate water wells and measure ■22- Sweasej Dam on Mad.

The areas of irrigated lajids, as well as other land uses, were determined in the land use s\irvey which was also conducted in 1958 • This survey and the resulting data are reported in Chapter III. Water Rights The data necessary for the detennlnation of the total water require- ments of an area must of necessity include the nature and extent of all rights which pertain to the water supply therein. For this reason, data with respect to water rights in general, and particularly those which pertain to the existing surface water diversions, are described in this report. Most of the surface water use in the unit is based on rijarian rights or on approprlative rights established \inder the provisions of the Water Commission Act of I91U. A few diversions are based on approprlative rights established prior to 191^. These earlier rights were Initiated by actual diversion and beneficial use of water, or by posting notice of intended appropriation at the point of diversion and recording such notice in the office of the recorder of the county. No diversions based on court adjudica- tions were noted in this investigation. As of October 1, I96O, there were on file with the State Water Rights Board 88 applications to appropriate water from the streams of the unit. Of these 88 applications, Sh were for various local uses, amounting to a total of about 30 cubic feet per second of direct diversion, and for storage of 1,625 acre-feet per annum. The other four applications were for major projects not in existence in I958. Two of these four were held by the California Water Commission under the provisions of Section IO5OO of the Vfeter Code for future diversion of 500,000 acre-feet per annum. The other two were held by the Himiboldt Bay Municipal Water District and were for diversion of 200 cubic feet per second and for storage of 120,000 acre-feet per annum. .2k- The California Law of Water Rights, as related to both surface gind underground water, is described briefly in Appendix C. A tabulation of data relative to the applications on file with the State Water Rights Board is presented in Table C-1 of Appendix C. Data pertaining to the apparent water rights exercised by the diversions described in this report are included in Table 6, described below. Surface Water Diversions An attempt was made to locate and obtain data with respect to all diversions of 10 acre-feet or more per year. Since very few diver- sion systems were previously mapped, aji intensive search of the unit by department personnel was necessary. Complete photographic coverage of the unit and a list of appropriate water rights were the chief means of locating diversions. Investigation of visible clues such as conduits, powerlines, and similar features, and of various water-using activities, and canvassing of residents were also of great assistance in the process. As each diversion system was located it was plotted on the photograph covering the site. Descriptions of diversion works were obtained generally through on-the-spot inspection; and other data such as history, uses, water rights, etc., by interviewing the owner, operator, or other persons familiar with the diversions. Certain of these data, such as water rights information, were verified to the extent feasible within the scope of this investigation. U. S. Geological Survey quadrangle maps were used in the field work, and to identify the diversion locations as explained below. Systems for direct diversion of water, as well as those providing for storage, were located. Systems in use in 1958^ a-nd also those used within the previous five years, unless reported to be abandoned, were ■25- Included. Reservoirs which had surface areas of about three acres or more were mapped. This size was considered the minimum that could be delineated on the aerial photographs used. Reservoirs located along, ajid operated in conjunction with, ditches ajid pipelines ajre shown on the leind and water use maps, but are not considered as separate systems nor are they assigned diversion locations. Similarly, points at which diversion conduits inter- cept minor intermittent streams, and receive small amounts of water in addition to the primary supply, are not considered as separate diversions. Systems by which diverters collect their own field runoff or spill for reuse are not considered as diversions or assigned diversion locations. If return flow from another water user's operation is red! verted, or if there is doubt as to the origin of the water, the diversion is delineated and assigned a number. Diversion systems of water companies or groups of water users are considered as single units; individual customer distribution points are not shovm on the maps. ' Diversion points and main ditches or pipelines used to convey water from them aire delineated on the 11 sheets of Plate 2, "Land and Water Use." The diversions are listed and described in Table 6. Location System for Surface Water Diversions For purposes of identification, each surface water diversion is assigned a location by relating its position plotted on the photograph to the U. S. Geological Survey quadrangle map of the area. These diversion locations include the n\;mibers of the townships, ranges, and sections in the federal land survey system where the diversions apparently are situated. The sections are subdivided into ij-O-acre plots (qtiarter- quarter- sections), and the diversion locations also indicate these plots. For example, diversion 6n/1E-15H1, shown on Sheet 5 of Plate 2 labeled "15H1," ■ 26- Sprinkler irrigation north of Areata AGRICULTURAL WATER USE T Irrigation pump on Mad River Diversion 6N/1E-8L1 is in the southeast quarter of the northeast quarter of Section I5, Township 6 North, Range 1 East, Humboldt Base and Meridian (H.B.&M. ) A second diversion in a l4-0-acre plot is distinguished by changing the final number "1" to "2", as for diversion 6n/1E-15H2. Descriptions of Surface Water Diversions Descriptions, history, and other information relating to surface water diversions were obtained by field inspection, by interview with water users or their representatives, and by reference to prior reports and official records. This information is summarized in Table 6. Data in the table are arrajiged by diversion location number within each subunit. Each location number is followed by the name of the owner, the source of water, the pur- poses served, the quantity of water diverted during 1958^ tlie extent of use, such as the number of acres irrigated and the method of application of water. If the purpose listed is not the usual use for that diversion, notation is made in the "remarks" column. The extent of domestic use is specified only when five or more connections are served. Watering of less than 10 head of livestock is considered to be a domestic use. The extent of irrigation use is based on the land use survey described in Chapter III. The types of water rights under which the respective diversions are considered to be made are indicated in Table 6 under "apparent water right." Diversions apparently made under rights based on the appropriative doctrine (see Page C-5, Appendix C) are listed as "appropriative." Those diversions for which the conditions for ripariaji use, also described in Appendix C, apparently prevail, but for which no appropriation was known to exist, are listed as "riparian." Diversions listed as appropriative may also be ripa.rian, althoiigh no attempt was made in such cases to determine the riparian status. -28- The actual ajnoiont of the right, if established and known, and a reference to the source of the data, are also included under "apparent water right . " In the case of an appropriative right , the amount tabulated is that found in the filing, if any, or in the application, or in the latest permit or license which may have been issued in connection with the application. The reference given for an appropriation initiated after the effective date of the Water Commission Act of 19114- is the number of the application on file with the State Water Rights Board. For an appropriation made prior to 191^^ the reference, if known, is the book and page number of the official records of the coxinty in which the diversion is located. Although the "miners inch" is now legally l/UO cubic foot per second, county records reveal that maaiy of the filings made prior to 19ll<- specified a four inch head (I/50 cubic foot per second). As many filings did not specify, no attempt was made to differentiate between the miners inches claimed. The determination of water rights under which the various diver- sions are made is based upon the best information available from the owner, from files of the State Water Rights Board and other official records, and from other sources. Although this information is believed to be accurate, it is emphasized that it is not based on sworn claims or testimony, and shoiiLd in no way be construed to represent a conclusive determination of water rights. Detailed descriptions of the diversion systems, including dams, pumps, and main conduits, as well as any special features, axe also given in Table 6. The diversion systems axe classified as to type - gravity, pump, or storage - according to the following definitions: Gravity diversion - A system in which water is taJcen from its natural course at a diversion structure amd conveyed by gravity through a caxial or pipeline to the area of use. Such a diversion may have a reservoir on the stream, but the capacity is small compared with the amount of water diverted and provides no significant carryover storage from winter to summer. -29- 2 O O < q: < 5 < tr 10 X a. < q: o q: o > X o a o o o o o: Q.

Storage diversion - A system consisting of, or including, a siiriace reservoir having significant carryover storage within each season or from season to season. Systems not exclusively of one of these basic types are listed as combina- tions of those types which best describe them. The "remarks" column contains such information as the names of former owners, known changes of ownership after 1958, and further details explaining entries in the other columns. Records of Surface Water Diversions Continuous or periodic measurements of the quantities of surface water diverted by kO of the 65 diversions in use in the -unit were made by the Department of Water Resources in I958. Detailed results of the meastire- ment program are reported in Table 7« Determinations of diverted quantities were made primarily by testing of pumps. These observations were supplemented by interviews of water users to obtain data on possible abrupt changes in operation between readings, periods of operation, etc. For each diversion measured. Table 7 gives the use, the point and method of measurement, and the monthly and total quantities diverted. Notations in the "use" column regarding the irrigation period indicate the overall period of irrigation, but not necessarily that daily or continuous irrigation was practiced throughout the period. The quantities given in the table are based on various methods listed in the column "Method of observation and calculations." Where monthly data were sxifficiently reliable, the quantities are shown.

The data, however, were sometimes not sufficiently detailed to justify a breakdown into monthly quantities. These cases are indicated by — MR — . Dashes are used to indicate that a quantity was not determined. The measurements are designated as estimates when only incomplete or somewhat imcertain data could be obtained. Index to Surface Water Diversions An alphabetical index to diversion naines and owners is provided in Table 8 at the end of this chapter. For each diversion, this table indicates the diversion location, subunit, and county. For convenience in finding data regarding individual diversions, the sheet number of Plate 2 and the pages on which pertinent data appear are also provided. Imports and Exports There were no imports of surface water into the Mad River-Redwood Creek Hydrographic Unit in 1958. There were three diversions from which water was exported, all into the Eel River Hydrographic Unit. The largest of these is the Sweasey Dam diversion located as 5N/2E-16g1, on the Mad River. All of the 3,866 acre-foot output from this diversion was exported for use at Eureka. The other two diversions, also from Mad River, were for irrigation of areas lying partly on each side of the hydrographic \jjiit line. These two diversions were not measured. One, 6n/1E-7L1, irrigated 38 acres in the Mad River-Redwood Creek Hydrographic Unit and ik acres in the Eel River Hydrographic Unit in I958. The other, 6n/1E-7J1, irrigated h acres and 16 acres in the two imits, respectively. Cons\jmptive Use In the Mad River-Redwood Creek Hydrographic Unit, virtual 1 y all of the consumptive use of applied water is in connection with irrigated -ivl- agriculture, lumber mill operations, and Torban uses. Consumptive use of water is defined as any type of use through which water is rendered unavail- able for reuse. Processes in which water is consumptively used are transpiration and building of plant tissue by vegetation; evaporation from water siirface, foliage amd adjacent soil; aind consumption and evaporation by urban and other nonvegetative types of land use. Certain uses of water, such as for hydroelectric power generation, fish culture, and mining operations, are essentially nonconsumptive. The total of applied water, from both surface and ground sources, consumptively used in the Mad River-Redwood Creek Hydrographic Unit is estimated to have been about i<-,500 to 5,000 acre-feet in I958. The amount consianed by irrigation use was about 2,700 acre-feet, the remainder being consumed about equally by municipal-domestic use and by lumber mill operations. Consumptive use for other purposes was negligible. .k2- TABLE 8 INDEX TO SURFACE WATER DIVERSIONS IN MAD RIVER - REDWOOD CREEK HYDROGRAPHIC UNIT Diversion nome Diversion location Subunit and county R ef erences ond/or owner Plate 2 sneet no.

LAUn USE This chapter presents a discussion of the procedures and the tabulated results of a survey of land use in the lyfeid River-Redwood Creek Hydrographic Unit in 1958. These results, as well as those of the water use data presented in Chapter II, are essential to the determination of future water requirements of the unit. A brief account of historical lajid use in the unit is presented to supplement the survey data. Historical Lajid Use Development within the Mad River-Redwood Creek Hydrographic Unit began, as mentioned in Chapter I, as a result of exploration of the coast in search of routes to the Trinity gold fields. The l850's saw the first urban developnents , beginning at Trinidad, eind the introduction of agric\il- ture, mainly on the smoother open lands near the coast. The use of lands specifically for recreational purposes was not significant in the \init until many years later. Urban land use in the unit remained small until the boom which followed World War II. Trinidad and Blue Lake, the oldest ajad only incor- porated towns, have in recent years been surpassed in area and population by the scattered unincorporated community of McKlnleyville . Several smaller communities are located in the coastal area of the unit. These communities, including Craimell, Fieldbrook, Korbel, Mapel Creek, emd Orick, owe their existence largely to the liomber industry. In fact, nearly all the urban centers in the unit include this type of industrial land use, as well as residential and commercial types. In relation to water use, and in acreage of developed lemd, agricul- tural lemd use is the major type in the Mad River-Redwood Creek Hydrographic -1^7- Unit. (Lands which are in an essentially undeveloped condition suid receive no applied water, even thoxigh they supply valuable timber and forage, are mapped as native vegetation for the purpose of this report.) Historically, , agriciiltiire has been a significant activity since the l850's. The remote- ness of this region from sources of supply and markets has largely determined the nature of its agric\iLture . Meeting the local demand for food — principally meat, dairy products, potatoes, etc. -- as well as feed for livestock, set the pattern of agriciilture for some 70 years. After I9OO dairying and beef raising were well established as the primary farm activltie Improvement of transportation in recent decades has made possible a wider variety of farm products. This trend began after completion of the rail line to Eureka in 191^^ but ein even greater change came after modem roads made trucking feasible. Most significant of these developments was the rapid expansion, steurting about 19^0, of the previously small nursery and truck indiistry. The following tabiilation of sales values of these crops in Humboldt County illustrates these changes during the early 19^0's. l9'4-o 19^5 Horticultiiral $76,000 $3^1,000 specialties Vegetables 23,000 37^,000 Though these are Humboldt County totals, the sharp rise is apparent and the new pattern has continued. In recent years, the value of horticultural production has been greater than that of any other farm activity except dairying. In acreage, however, pasture still dominates the agriciiltural land use, comprising more than 90 percent of the irrigated lands and 70 percent of the dry-farmed lands in 1958 • Irrigation, the largest water \ising activity, has likewise been very largely a development of the last two decades. As of 1939 there were only nine irrigated farms and 179 acres irrigated in the Mad River drainage area. The 1958 siirvey, however, showed that over 3^300 acres in the unit were irrigated. Recreational activities, mainly hiinting and fishing, have been pursued in the unit since its settlement. Until recent years, however, I there was only a small amount of land use devoted to recreation. Even in the 1958 survey, only about 300 acres were found to be actually so developed. L The unit has, nevertheless, an abundance of lands naturally suited to recreational uses. The redwood forests and diverse types of coastal and mountain terrain in the unit are some of the State's finest scenery. Over 10,000 acres of these lajids have been set aside as public parks. Present Land Use A detailed description of the survey of land uses conducted in 1958 is described in the following paragraphs. The land uses mapped in this survey fall into four major categories: irrigated lajids, dry- farmed I lands, urban lands, and recreational lands; and one minor category: naturally high water table lands, such as meadowlands and marshes. Lands not falling into any of these five categories were mapped as "native vegetation." The location and extent of the lands falling into each of these categories are delineated on Sheets 1 through 11 of Plate 2. The acreages of the various I land uses within each sub\init are presented in Table 9« The values represent gross acreages, and include those nonwater-service axeas such as roads, ditches, farm building and storage areas, and miscellaneous rights-of-^ra.y, which were too small to be separated from the mapped areas in which they were located. -1^9- Ijj _l CD < cn 3 Q < CO in 2 O I Q. < cr o o (T O > X :»: UJ UJ tr o Q o o o UJ cr I cr UJ > < C o o V V- CC in a> o o O c 3 >. — 0) o — ■o 2,c c c o o CVJ o no O on O O m CO o C +J o -o O iH M O I-:) g bota 1-1 n cu s o o i o ■p o 0) 3 I m o o o o s° o o o o cu w q -p >. o 0} > u V I' S o O O o ir\ VD VO ir\ CVJ H o o w o H I M U O t o +5 2 00 o o o o O o vo u^ t^ t^ m H o >CVJ O Ol 8 CVJ a -p at +J o E-i >. ■p o o o •d >^ H -P O f-l a i-( w S -50- Methods and Procedures The location of surface water diversions emd the land use survey were accomplished by relating field observations to aerial photographs having I a scale of about 1:20,000. The use of stereoscopes was of great assistajice in this work. As each surface water diversion was located, it was plotted on the aerial photograph. Following this, the use sund extent of each par- I eel of land were determined, and delineations and annotations made accordingly on the photographs. The hydrographic unit was traversed by automobile as completely as roads and terrain permitted, ^-ftiere necessary because of poor I accessibility, inspections were made on foot. A system of annotations designed to indicate both the broad types of land use mentioned in the previous section, and subclassifications denoting specific uses, was employed. Agricultural lands were surveyed to determine whether or not parcels were irrigated and what crops were raised. This infor- mation was then annotated on the photographs. The crops observed were identi- fied by general crop groups, as well as the specific crops present. A list of the general groups of crops and the specific crops com- prising each group are listed below, with the crops found in the unit in 1958 underlined: G - Grain and hay crops VJheat, barley, oats, miscellaneous F - Field crops Cotton, saf flower, flax, hops, sugar beets, corn (field or sweet). Grain sorghums, castor beans, miscel 1 aneous P - Pasture Alfalfa , clover, mixed , native, induced high water table native, sudan .51- T - Truck Artichokes, asparagus, teans (green or dry), cole crops, carrots, celery, lettuce, melons, squash, cucumbers, onions, garlick, peas , potatoes , sweet potatoes, spinach, tomatoes, f lovers , nursery , bushberries, strawberries , peppers, mi s c ellane ous D - Deciduous fruits and nuts Apples, apricots, cherries, peaches, nectarines, pears, plums, prunes, figs, almonds, walnuts, miscellaneous An example of an aerial photograph with land use data delineated on it is shown on Page 53 • After completion of the field mapping, the data delineated on the photographs were transferred to copies of U. S. Geological Siirvey quadrangle maps reproduced at a scale of 1: 2^1-, 000. This proced\ire -vras necessary to bring the delineated areas to a common scale for accurate determination of acreages, since the scale of the aerial photographs utilized varied widely. A series of these maps showing the location of all diver- sions, and the fields associated with each irrigation diversion, was colored according to the land use categories and was reveiwed by local parties concerned. These maps were then used in the preparation of Plate 2. Another series of these maps was used in computing the acreages of the land uses. Each delineated area on these maps was majiually cut out and was carefully weighed on an analytical balance. These weights were converted to acreages, using ratios determined for the individual maps. This method has proven to be a very expedient ajid accurate means of area determination where a large number of small parcels are involved. Irrigated Lands Irrigated lands, as designated in this report, include all agri- cultiiral lands which receive water artificially. As these lands were noted ■52- b^y. r^y* Example of Land Use Delineated on Aerial ir'notograpii Symbols used on this photograph: ">*?5'.«<^ Irrigated Lands Dry-farmed Lands iP3 - mixed pasture nP3 - mixed pastujr-e iP3x - mixed past-are, nG6 - miscellaneous or partial mixed hay and grain irrigation nT12 - potatoes iPF - pasture, fallow nTl6 - flowers and nursery iT6 - carrots Dl -, • u. ji • rm^ -PI ^ ";;7T^ - apples intercropped iTlo - floi-.-ers and T20 •+!, 4- -u • ^ with strawberries 12 - new lands being prepared for futiJire use nursery iF6 - corn Urban Lands UI3 - storage areas UR - residential Miscellaneous Lands M - native vegetation W/1 - water (reservoirs, etc. ) IW2 - meadowland -53- in the field survey they were identified as such by the symbol "i" as on the sample photograph. The fields of various crops and of "idle" land were identified with specific water sources and the acreages determined accordingly. Idle irrigated lands are defined as lands which were not irrigated in 1958, but had irrigation facilities and had been irrigated within the preceding three years . Fallow irrigated lands are those cultivated lands which have facilities for irrigation and may be irrigated during the year of survey, but at the actual date of survey were only tilled ajid not planted to a crop. In 1958, there were 3,3^0 acres of irrigated lands in the Mad River-Redwood Creek Hydrographic Unit. Of this total, 87 percent were in past\are-type crops ^ seven percent were in truck crops, mainly nursery, one percent miscellaneous, and the remaining five percent were idle or fallow. Acreages of irrigated lands within the various subunits are reported in Table 10 by surface diversion. For each irrigation diversion, the acreage of each crop group and, where applicable, the acreage previously irrigated but not cropped in 1958, are tabulated. Any of these lands which received a supplementary supply from ground water are indicated. The acreages to which ground water only was applied are also listed. On Plate 2, irrigated lands are grouped in just three categories: (1) those which were cropped and to which water was actually applied during the year of survey; (2) those lands which received only a partial supply of water in I958; and (3) those which were idle or fallow. The use of grovmd water is indicated by cross-hatching. .5!^- TABLE 10 IRRIGATED LANDS IN MAD RIVER - REDWOOD CREEK HYDROGRAPHIC UNIT 1958 Cm acres) Diversion or other source serving irrigated londs Mned pasture Field crops Trucll crops Deciduous orctiard Total lands 1 r r igoted Irrigated" idle or fal low Total Diversion locotion Diversion owner Nursery Ottier H B S: M Beaver Subunit (No irrigated lands) 1 Big Logoon Subunit 9N/1W-26L1 George McAllister 9 9 9 10N/1E-29F1 William McNeil b 56 56^ 56^ 10N/1E-29L1 William McNeil _2U^ _ _ Jk^ b Total Surface Water Supply 89= 89= 89= Total Ground Water Supply gg g 2lt 2h Total Big Lagoon Subunit 111 2 113 113 Humboldt County 6N/1E-6Q1 Joe W.

Naturally High Water Table Lands In addition to the lands which receive applied water as described above, there are lands supporting vegetation which utilizes water from a naturally high water table, such as raoiintain meadows or certain lands adja- cent to lakes and streams . These lands are divided into two groups : ''meadowlands" where the water table is normally below the surface; and "marsh" which is under water much of the year, and supports a growth of tules, cattails, bullrushes, and similar vegetation. These two groups are designated "naturally irrigated meadowlands" and "marsh or swamp" on Plate 2. Dry-farmed Lands Dry- farmed lands are those lands normally in crop but which do not receive applied water. This category includes all lands so farmed, whether or not a crop is produced in the year of survey. Dry-farmed lands are called "idle" if entirely uncultivated in the year of survey, and "fallow" if tilled but without a crop. Lands which had been idle for more than three years and appeared to have reverted to native vegetation were so mapped. It should be noted that the term "dry-farmed" as used herein refers to the farming practice on these lands, and not to a lack of soil moisture . Since noncultivated rangelands are usually indistinguishable from other lands with native cover not used for grazing purposes, no attempt was made to segregat e them. Both types are included in native vegetation. V/ater use in both cases is essentially the same, and is dependent upon precipitation. ■60- Urban Lands Urban lands include the total areas of cities, towns, small conimunities> and industrial plots which are large enough to be delineated. Also included are parks, golf courses, racetracks, and cemeteries within or near urban areas. The reported acreages of urban land use represent gross delineations, including streets and vacant lots, and are therefore not necessarily fully developed at the present time. In this survey the boundaries of urban communities were delineated to include all lands with a density of one hoiise or more per two acres. Recreational Lands Recreational lands were mapped on aerial photographs in the field in four categories: (l) residential, (2) commercial, (3) camp and trailer sites, and {k) parks. Recreational "residential" lands include permanent and summer home tracts within primarily recreational areas. The estimated density of homes per acre was also indicated in the course of the survey. Recreational "commercial" lands include those containing motels, resorts, hotels, stores, restaurants, and similar commercial establishments in primarily recreational areas. Lands mapped in the "camp and trailer sites" category include those areas so used within primarily recreational areas but outside the boundaries of public parks. The entire area within the boundaries of parks was included in the "parks" category without regard to the extent of development thereon. Obviously, nearly all the mountainous, seashore, and water surface areas are suitable for some use such as hunting, fishing, hiking, picnicking, ajid other recreational activities of this nature. For the piirpose of this land use survey, however, except for parks, consideration was given only to those lands where some fairly intensive development requiring water service was located. -61- Right: Gravel plant near Blue Lake Below: Lumber Mill at Korbel INDUSTRIAL LAND USE 9^^iv r. : The recreational lands are tabulated by the above four categories in Table 9- However, all recreational lands are indicated alike on Plate 2. In the case of officially designated recreational lands, the areas delineated and tabulated are not necessarily fully developed. Prairie Creek Redwoods State Park is the most notable example of this. Native Vegetation Lands which are essentially in a native state, and not included in any of the above categories, as well as scattered residences and other isolated uses too small to be delineated, were mapped as "native vegetation." However, in addition to the lands so mapped, the total acreage reported in this native vegetation category includes lands which were mapped as water surface and farm building areas, including dairies, feed lots, etc. 'The total of all these lands was some 571^^00 acres, or about ^G percent of the Mad River-Redwood Creek Hydrographic Unit, in 1958- Most of these lands, even in their native state, are used for commercial timber production, livestock range, and recreational activities such as fishing, hunting, hiking, and picnicking. ■63- ciiAPTEr. rv. LAiro class if icatioii Calculations of fut\ire vater requirements will be based in a large part on a classification of lands vith regard to their potential for irrigated agricultm-e and recreational development. The results of such a land classification conducted in the Mad River-Redwood Creek Ilydrographic Unit are presented in this chapter. Lands were not classified in this survey with respect to their potential for urban development. The use of lajids for urban piorposes is closely related to population at any given time, and it is planned to defer designation of these lands until estimates of popuJLation and related economic studies are made in connection with determinations of future water require- ments. The former Division of Water Resources made a reconnaissance classification of lands of the State which was reported in State Water Resources Board Bulletin No. 2, "Water Utilization and Requirements of California," June 1955- In that report, the area discussed herein is contained in the "Mad River" and "Redwood Creek" units. The data on agricultural lands reported herein ai'e in considerably greater detail than the information in Bulletin llo. 2. Tliis bulletin also includes additional data on classification of potential recreational lands not contained in Bulletin No. 2. This report is likewise more detailed as to land classification than Bulletin No. 58, "Northeastern Counties Investigation," v^hich covers the portion of the unit within Trinity County. Results of the land classification survey conducted in the Mad. River-Redwood Creek Ilydrographic Unit in 1959 are presented pictorially on Plate 3, "Classification of Lands," Sheets 1 througli 11. Tae total acreages of each classification are enumerated by subunits in Table 12. .65- Methods and Proced\;u"es The general methods and procedures used in field mapping, area determinations, and tabulation of acreages were essentially the same as those described for the land use survey in Chapter III. An example of land classification delineations on an aerial photograph is shoxim on Page 69. The standards used in the classification of lands are given in detail in Table 11. Table 11 LAND GToASSIFICATION STANDARDS Land class: symbols : Characteristics Irrigable Lands V - These lands are level or slightly sloping and vary from smooth to hummocky or gently undulating relief. The maximum allow- able slope is six percent for smooth, reasonably large-sized bodies lying in the same plane. As the relief increases and becomes more complex, lesser slopes are limiting. The soils have medium to deep effective root zones, are permeable throughout, and free of salinity, alkalinity, rock or other conditions limiting crop adaptability of the land. These lands are suitable for all climatically adapted crops. H - These are lands with greater slope and/or relief than those of the V class. They vary from smooth to moderately rolling or undulating relief. The maximum allowable slope is 20 percent for smooth, reasonably large-sized bodies lying in the same plane. As the relief increases and becomes more complex, lesser slopes are limiting. The soils are permeable, with medi\:mi to deep effective root zones, and are suitable for the production of all climatically adapted crops. The only limitation is that imposed by topographic conditions. M - These are lands with greater slope and/or relief than those of the H class. They vary from smooth to steeply rolling or undulating relief. The maximum allowable slope is 30 per- cent for smooth, reasonably large-sized bodies lying in the same plane. As the relief increases and becomes more complex, lesser slopes are limiting. The soils are permeable, with medium to deep effective root zones, and are suitable for the production of all climatically adapted crops. The only limitation is that imposed by topographic conditions. -SG- Table 11 (Continued) LAiro CLASSIFICATION STANDARDS Land class: symbols : Characteristics Any variations from the foregoing, as defined, are indicated by use of one or more of the following symbols: w - Indicates the presence of a high water table, which in effect limits the present crop adaptability of these lands to pasture crops. Drainage and a change in irrigation practice would be required to affect the crop adaptability. s - Indicates the presence of an excess of soluble salts or exchangeable sodiiom in slight amounts, which limits the present adaptability of these lands to crops tolerant to such conditions. The presence of salts within the soil generally indicates poor drainage and a medium to high water table. Reclamation of these lands will involve drainage and the application of small amounts of amendments and some addi- tional water over and above crop requirements in order to leach out the harmful salts. ss - Indicates the presence of an excess of soluble salts or exchangeable sodium in sufficient quantity to require the application of moderate amounts of amendments and some additional water over and above crop requirements in order to effect reclamation. h - Indicates very heavy textures, which in general make these lands best suited for production of shallow-rooted crops. 1 - Indicates fairly coarse textures and low moisture -holding capacities, which in general make these lands imsuited for the production of shallow-rooted crops because of the frequency of irrigations required to supply the water needs of such crops. p - Indicates shallow depth of the effective root zone, which in general limits use of these lands to shallow-rooted crops. r - Indicates the presence of rock on the surface or within the plow zone in sixfficient quantity to prevent use of the land for cultivated crops. Urban Lands UD - The total area of cities, towns, and small communities presently used for residential, commercial, recreational, and industrial purposes. Such lands lying within areas to be immdated by projects authorized for construction are excluded. -67- Table 11 (Continued) LMJD CLASSIFICATION STANDARDS Land class: symbols : Characteristics Recreational Lands RR - Existing and potential permanent and summer home tracts within a primarily recreational area. The estimated number of houses, under conditions of full development, is indicated by a num- ber in the symbol, i.e., RR-3 is suitable for three houses per acre . RC - Existing and potential conmiercial areas vhich occur within a primarily recreational area and which include motels, resorts, hotels, stores, etc. RT - Existing and potential camp and trailer sites within a primarily recreational area. RF - Existing county, state, federal, and private parks, race- tracks, and fairgrounds. Miscellaneous Lands F - Presently forested lands, or lands subject to forest management, which meet the requirements for irrigable land but which, because of climatic conditions and physio- graphic position, are better suited for timber production or some type of forest management program rather than for irrigated agriculti;ire. Vm - Swamp and marshlands which are covered by water most of the time and usually support a heavy groirth of phreatophytes. N - Includes all lands which fail to meet the requirements of the above classes. Major Categories of Land Classes The lands mapped are grouped into four major categories: (l) irrigable lands, (2) urban lands, (3) recreational lands, and (k) miscel- laneous lands. These categories are described in detail in the following paragraphs . -68- Example of Land Classification Delineated on Aerial Photograph (See Table 11, pages 66-68, for symbol explanation) -69- p Irrifflble Lands Irrigable lands are grouped in appropriate classifications accordij to their suitability for development linder irilgated agriculture and their crop adaptability. Presently irrigated lands are included within these classifications, but urban Ismds and recreational, lands are not classed as to irrigability. The time clement with respect to when the lands might be developed did not enter into these determinations, except that suitabilii for irrigated agriculture vas necessarily considered in light of present agricultiiral technology. There are many factors which influence the suitability of land for irrigation development. Since soil characteristics and the physiograph; of the landscape are the most stable of these factors, they were the only ones considered in the survey in classifying lands as to their irrigability The characteristics of the soil were established by examination of road cut ditch banks, and the material from test holes, together -vrith observations of the type and density of native vegetation and crops. Representative slopes throughout the area were measured with a clinometer. Other aspects, such as those economic factors related to the production and marketing of climatically adapted crops, the location of lands i/ith respect to a water ll supply, and climatic conditions, were not considered in the basic classifier tion. These latter factors are very important in estimating the nature of ' futirre cropping patterns and practices, and will be given due consideration when estimates are made of future water requirements. Urban Lands It is recognized that futvtre lorhan expansion will encroach upon some of the irrigable lands. The location and extent of this type of devel ment is a function of many variables.

Therefore, only those leinds devoted to urban uses in 1958 are designated as "urban" lands. Reci-eational Lands Present trends indicate an expanding rate of use and demand for recreational facilities throughout the State. In view of these trends and the ever- increasing population, it is recognized that there wlU be a demand for substantial land areas for recreational purposes. This is particularly true of the mountainous and coastal regions where this type of development is expanding rapidly at the present time. Generally speaking, all mountainous and coastal lands are suitable for some recreational use such as hunting, fishing, and similar outdoor activities. However, for purposes of this survey, lajids classified for recreational use were limited to those which are now, or may in the future, be used intensively for permanent and summer home tracts, camp and trailer sites, and parks outside of urban areas. These are lands requiring intensiv water service. Primary considerations for classification of home tracts and camp i and trailer sites were such physical factors as soil depth, slope, and rocki nessj such aesthetic values as view, nearness to lakes, streams or seashore, or density and type of forest canopy suitable for the respective uses; and the plans of federal and state forest officials. An important factor in locating potential camp and trailer sites is the availability of a water supply. Isolation from existing roads did not influence classification. The total areas of existing federal ajid state parks, rather than the specific areas of potential intensive development therein, are included with the recreational lands on Plate 3- Fo^^ other parks, only the areas -72- ilk at 'rairie Creek Redwoods 5tate Park ni% jm §\ . „ 7 o O 01 a.
