Bureau of Reclamation Year: 1931, 2008, 2006 Information Of Interest Source of water supply: Upper Klamath Lake, Lost River and Clear Lake. Area of drainage basin: 3,700 square miles. Length of irrigation season: From April 15 to September 30 - 168 days. Average elevation of irrigable area: 4,100 feet above sea level. Average annual rainfall on irrigable area: 12.7 inches. Average of recorded temperatures, 12 years: highest 97, lowest -4 F Character of soil of irragable area: Disintegrated basalt, volcanic ash, and diatomaceous eart, being largely classifid as Yakima sandy loam. Principal products: Alfalfa, hay, grain and vegetables; stock,poultry, and dairy products. Principa; markets: Portland Oregon; Sacramento and San Francisco, Ca. Limit of area of farm units: 160 acres. The irrigation plan of the Klamath Project provides for the storage of water in Upper Klamath Lake, lying just North of Klamath Falls, Oregon, and in Clear Lake Reservoir, California, at the head of Lost River. Water for lands in Langell Valley and in the vicinity of Bonanza will be supplied from Clear Lake Reservoir and from Gerber Reservoir. Water for all other lands will be supplied from Klamath Lake. Water is diverted from the outlet of Upper Klamath Lake just above the Link River Dam, into the "A" Canal which extends nine miles in a southeasterly direction, and supplies the canals on both sides of Lost River. Water for the Tule Lake lands, which are served by the "J" Canal, is discharged into Lost River from the C-G Canal and from this point to the diversion dam two miles southeast of Merrill; Lost River being used as a carrier. At the diversion dam, the water is diverted into the "J" Canal. One of the principal features of the Klamath Project is the reclamation of the lands in the bed of Tule Lake. These lands are being reclaimed in a double sense: first, by causing the waater recede and, second, by constructing irrigation works to irrigate the lands uncovered. The lowering of the water surface in Tule Lake is being brought about by evaporation from the lake itself and by preventing inflow. The works designed to prevent inflow consists of Clear Lake Reservaoir, and the Lost River diversion canal. Clear Lake Reservoir is located at the head of Lost River and stops the flood waters coming in from abouve. Flood waters coming in Lost River below Clear Lake are diverted from Lost River int the Klamath River through the diversion canal. The works designed to provede irrigation service for the uncovered lands consist of a diversion dam on Lost River tow miles southeast of Merrill, the "J" Canal and lateral system. The Keno Canal has been constructed on the West side of Link River and extends from the Link River Dam to a point about one mile below; the river in this distance makes a drop of about 50 feet. The Keno Canal was designed to develop power and to supply water for irrigation to lands on the west of Klamath River, also, to the marsh lands around Lower Klamath Lake. Irrigation from the Keno Canal has now been abandoned and the United States has installed no power plant. The Keno Canal has been leased to the California-Oregon Power Company. The Pricipal features of the project are the Clear Lake Reservoir, the Gerber Reservoir, the Link River Dam, the Main "A" Canal with a tunnel 3300 feet long, the precast concrete flume 4300 feet long on the "C" Canal, the di2 diversion dams on the Lost River, the Lost River pipe lines on the C-G Canal and the main canals and laterals and 128 miles of open drains. Irrigation service may now be provided for about 101,000 acres or irrigable land.

It is located in Klamath County, Oregon, and in Modoc and Siskiyou Counties of California. Project headquarters is located at the principal city of Klamath Falls, Oregon, which has a population of about 35>700, including suburbs. Smaller towns on the project in Oregon are Merrill, Malin, and Bonanza. The town of Tulelake, California, was established in 1931 near the center of the Tule Lake Division. Climate. The mean temperature for the wannest month is 630 F. The coldest month has mean temperature of 29? F. Summer nights are cool. The annual rainfall is about 13 inches, of which about 3?-inches fall during the growing season of 90 to 130 days. Topography, soils, and crops. The project area is about ^-,100 feet elevation above sea level. The surface topography is generally smooth and flat for the large areas of lake bottom, and gently sloping on the higher lands. Peat and muck soils are common in the recent lake bottoms. Soils vary from sandy loam to clay on other parts of the project. The principal crops grown are alfalfa, malting and feed barley, potatoes, clover seed, and irrigated pasture and other forage. Stock raising is an important enterprise. Industry and transportation. Farming and lumbering each provide the major portion of the economy of the Basin. Three major railroad lines, one major highway and many secondary highways, and two airlines serve the project area. Plan and purpose. The project serves 211,000 acres. The water supply is provided by two main water courses, Klamath River and Lost River and their tributaries. Besides storing, diverting, and distributing water for irrigation, project facilities have reclaimed by drainage large areas formerly inundated by Lower Klamath and Tule Lakes* Flood waters of Lost River, which terminates in Tule Lake, are diverted to the Klamath River through the Lost River Diversion Channel. This channel is also used to carry irrigation water in the opposite direction in the summertime. Another principal function of the project is water-level control for the Tule Lake and Lower Klamath Lake National Wildlife Refuges. Upper Klamath Lake on the Klamath River is the principal storage reservoir, having an active capacity of 52U,800 acre-feet.

  	Citation × Citation Citation Abstract Copy Title: Recent paleolimnology of Upper Klamath Lake, Oregon Author: United States. Bureau of Reclamation Year: 2001, 2005 Recent Paleolimnology of Upper Klamath Lake Eilers et al. 2001 ABSTRACT Sediment cores were collected from Upper Klamath Lake in October, 1998 and analyzed for 210Pb, 14C, 15N, N, P, C, Ti, Al, diatoms, Pediastrum, and cyanobacterial akinetes. These results were used to reconstruct changes in water quality in Upper Klamath Lake over the last 150 years. The results showed that there was substantial mixing of the upper 10 cm of sediment, representing the previous 20 to 30 years. However, below that, 210Pb activity declined monotonically, allowing reasonable dating for the period from about 1850 to 1970. The sediment accumulation rates (SAR) showed a substantial increase in the 20th century. The increase in SAR corresponded with increases in erosional input from the watershed as represented by the increases in sediment concentrations of Ti and Al. The upper 20 cm of sediment (representing the last 150 years) also showed increases in C, N, P, and 15N. The increases in nutrient concentrations may be affected to various degrees by diagenetic reactions within the sediments, although the changes in concentrations also were marked by changes in the N:P ratio and in a qualitative change in the source of N as reflected in increasing S15N. The diatoms showed modest changes, particularly in the upper sediments, with increases in Asterionellaformosa, Stephanodiscus hantzschii, and S. parvus. Pediastrum, a green alga, was well-preserved in the sediments and exhibited a sharp decline in relative abundance in the upper sediments. Total cyanobacteria, as represented by preserved akinetes, exhibited only minor changes in the last 1000 years. However, a taxon which was formerly not present in the lake 150 years ago, Aphanizomenon, has shown major increases in recent decades. Although the mixing in the upper sediments prevents high-resolution temporal analysis of the recent history (e.g. last 30 years) of Upper Klamath Lake, the results demonstrate that major changes in water quality likely have occurred leading to a major modification of the phytoplankton assemblage. The changes in sediment composition are consistent with land use activities during this period that include substantial deforestation, drainage of wetlands, and agricultural activities associated with livestock and irrigated cropland.

The extent of the area irrigated, or that may be irrigated by reason of Bureau of Reclamation activities, is approxi-mately 140,000 acres. This includes about 20,000 acres suitable only for pasture and approximately 12,000 acres of good land in the Tule Lake division not yet opened for settlement. Within the older developed sections of the project the soil is mostly of a sandy loam . type that is particularly suitable for growing potatoes and summer vegetables as well as all of the ordinary crops that thrive in a cool, tem-perate climate. The price of this type of land ranges from $ 100 to $ 200 per acre. The water- right cost, which origi- Klamath Falls, Oregon, the prolect office headquarters nally was about $ 55 per acre, is approximately half paid up. The balance has an average of about 25 years to run without interest. Operation and maintenance costs usually run about $ 1.25 an acre per annum. I R R I G A B L E L A N D S The Tule Lake division of the project, which will eventually comprise about 32,000 acres of agricultural land and about 5,000 acres of thin soil land good only for pasture, carries a construction charge of $ 88.35, with 40 years in A! Klamath : desert. Looking~ southwest up Lan Valley from a point 4 miles west of Lorella, Ore which to pay without interest. No payments have been required to date, but the Secretary of the Interior will soon issue public notice announcing the commencement of pay-ments, which will be approximately $ 2.20 per acre each year. In addition to the construction charge, there is an operation and maintenance charge which will probably run between $ 1.50 and $ 2 un acre a year. These lands are of lacustrian origin and are very fertile. They are particularly adapted to the growth of small grains, alfalfa, and pasture grasses. Patented land in this division sells for $ 50 to $ 100 per acre. Patented lands in private ownership, where of goc; d quality, well improved and conveniently situated, can be purchased for from $ 150 to $ 200 per acre. Good lands not so well improved nor so desirably located sell at around $ 100 per acre. There is very little undeveloped, privately owned good land on the project. Small tracts of 5, 10, or 20 acres, located along paved highways and within 6 to 8 miles of Klamath Falls, are obtainable at from $ 200 to $ 400 per acre. W A T E R S U P P L Y The Klamath project is ! ortunate in having an abundant water supply for all lands susceptible of irrigation. The map on the inside of the back cover page shows the location of the three reservoirs and their immediate proximity to the lands they serve. The irrigable project lands lie between elevations of 4,035 and 4,070 feet above sea level and occupy the Klamath Basin and the Valley of Lost River, situated in south central Oregon and north central California, about 150 miles east of the Pacific coast. The average annual pre-cipitation is 12.51 inches. SCHOOLS Klamath County schools are run on the county unit basis Public School in Klamath Falls and are fully up to standard. Busses run at county expense transport rural children to and from school, and there is no lost time on account of bad weather. Within the county there are 9,242 children of school age, 4,107 of these within the city of Klamath Falls. The high school enrollment for Klamath Falls is 1,156, and for the remainder of the county is 459. There are 9 high schools in the county that employ 62 teachers. The grade schools employ 185 teachers, of whom' 76 are in the city of Klamath Falls. : let of concrete flume, Canal C, of the main project structures R E C R E A T I O N No part of the United States affords more interesting and attractive recreational areas than are found near at hand and in all directions from the Klamath project. From 1 to 2 hours in any kind of an automobile is sufficient to land one on the banks of a cold mountain stream inhabited by many wary trout or alongside the shores of any one of a half dozen crystal lakes, where boating and bathing may be enjoyed to the full. Some of the lakes that are conven-iently located with reference to the project, and where many summer camps as well as extensive hotel and camp accommodations already exist, are Upper Klamath Lake, Lake of the Woods, Crater Lake, Diamond Lake, Crescent I., ake, Ode11 Lake, and Paulina Lake. The most distant of the lot, Paulina Lake, can be reached in 3 hours' driving from Klamath Falls. Some of the important recreational areas lying in convenient distances from the project are shown in the ilh~ strationsa ccompanying this chapter. The principal water supply is in Upper Klamath Lake, where regulation provides a possible storage of about 524,800 acre- feet, and this with the natural inflow insures the lands served from this source an adequate water supply at all times. Under the terms of the contract dated February 24, 1917, between the United States and the California- Oregon Power Co., the power company was given the right to regulate the outflow of Upper Klamath Lake, subject to existing rights and the prior rights of the Klamath project for water for irrigation. To regulate the outflow, the company, in 1921, constructed the Link River Dam at a cost of about $ 310,000. Storage for the lands on the west side of Langell Valley and a portion of the lands in the Horsefly irrigation district is provided by Clear Lake Reservoir. This reservoir, lying just across the line in California, is the source of Lost River and has a total capacity of 454,000 acre- feet, most of which was made available during 1931 by the construction of a channel from the outlet works to the deeper portion of the reservoir, a distance of about 6 miles. The reservoir is also used for flood storage for the protection of lands in the Tule Lake division. Gerber Reservoir, on Miller Creek, a tributary of Lost River, has a storage capacity of 94,000 acre- feet and fur-nishes a water supply for the lands on the east side of Lost River in the Langell Valley division. This reservoir also provides for the storage of flood water for the protection of lands in the Tule Lake division. Water from Upper Klamath Lake is diverted to the main or " A" canal from the east side of Link River, the outlet of the lake, several hundred feet below the lake and a few I I / Klamath River near Klamath Falls k River diversion dam Alfalfa field near Malin, Oreg. Two cuttings are grown, which yield 2- 4 tons per acre on the older project lands, and 3- 6 in Tule Lake section hundred feet above Link River Dam. Water for all lands in the main and pumping divisions and for a portion of the lands in the Tule Lake division are diverted through the " A" canal. Additional water for the lands in the Tule Lake division is diverted from the Klamath River, through the Lost River diversion channel ( reversing the direction of flow), and spilled into Lost River, frcm which it is diverted to the " J" canal at a point about 3 miles southeasterly from Merrill, Oreg. At this point the river level is raised about 12 feet by means of the lower Lost River diversion dam, a concrete structure of the Ambursen type, with a crest length of 204 feet. The Lost River diversion channel leads off from Lost River at a point about 10 miles southeast of Klamath Falls, Oreg., immediately above a hollow U- shaped concrete dam which raises the river level about 23 feet. Prior to the Irrigating a 65- acre field of potatoes; showing application of m irrigation season the flow of Lost River is diverted to the Klamath River and wasted; however, after the spring flood flow of Lost River has passed and water for irrigation in the Tule Lake division is required, the flow of Lost River is ~ assed through the dam and down to the " J" canal. This flow is augmented, when demand is heavy, from Klamath River as indicated ahve. Lands on the east side of Langell Valley division are served by the north canal, which diverts water from Miller Creek at the Miller Creek Dam, located about 6 miles below Gerber Dam. At this point the water surface in Miller Creek is raised by placing flashboards against wooden trestles, the grade of the canal and that of the stream being substan-tially the same elevation. The lands on the west side of Lost River in the Langell Valley division are served by the West Canal, which diverts water from Lost River at the Malone Dam, located about 42 miles southeasterly from Klamath Falls, Oreg. At this point the level of Lost River is raised about 18 feet by means of an earth diversion dam. Clear Lake Reservoir provides storage for the West Canal. TOWNS Klamath Falls, Merrill, Malin, and Bonanza are project towns, the first named being the principal city in southern, Oregon east of the Cascades. It has a population of approximately 16,000 and is the distributing center for a large territory. Klamath County has a population of 32,400, one- half residing in the city of Klamath Falls and perhaps 4,000 more in suburban districts only a few miles away. Merrill and Malin are small towns within the irrigated area with populations of six or seven hundred each. In Klamath Basin are some 1,800 farms and approximately as many farm families. LUMBERING Approximately 30 mills and box factories are in operation, this district being the largest manufacturing center of box shook in the United States. The Klamath district contains the heaviest stand of yellow pine left in the United States. Throughout the spring, summer, and fall all lumber com-panies maintain large pay rolls both in the plants and in the lumber camps. Lumber contributes greatly to the heavy traffic originating at K! amath Falls, making this city the second largest shipping point in Oregon. The majority of the mills and box factories are located in or near Klamath Falls. T R A N S P O R T A T I O N Two main- line railways, the Southern Pacific and Great Northern, enter Klamath Falls and traverse the project throughout its longest dimension. Hard- surfaced highways radiate from Klamath Falls in all directions, connecting with Portland, Sun Francisco, and Salt Lake. These high-ways supplemented by county market roads penetrate all sections of the project, with the result that few farms are more than a mile from a hard- surfaced outlet. CLIMATE The Klamath Basin has a remarkably pleasant and healthful climate. Winters are not cold, and summers are not hot. Precipitation, which amounts to about 12): inches a year on the average, falls mainly from November to April. Late and early frosts are to be expected, and occasionally light frosts occur even in the summer months. me on the Main division of the project A G R I C U L T U R E The principal crops grown are potatoes, alfalfa, small grains, and vegetables. The yield of small grains in the Tule Lake area is unusually high. Oats frequently make 100 bushels per acre; barley runs from 60 to 80; and any good wheat field will thresh out more than 40 bushels per acre. Potatoes, when conditions are right, are par excelience the big money crop. A good yield of tubers is considered to be around 150 sacks of U. S. No. 1' s per acre, and every year a few fields are reported with yields of double that amount. The price for potatoes is unstable, depending on the market demand, and ranges from about 50 cents to $ 1.50 a sack. The quality of Klamath potatoes on the Sun Francisco market is recognized as the best, and the price usually ranges from 10 to 20 cents a sack higher than is paid for Washington and Idaho production. Flock of 6,000 turkeys being fattened for market L I V E S T O C K Cattle. On account of its geographical location, sur-rounded as it is with immense areas of sagebrush plateaus and forest ranges, the Klamath project is, and probably always will be, essentially a stock country. Its cheap forage, abundant water and mild winters offer ideal con-ditions for the wintering of range stock and the fattening of mature animals for market. Favorable feeding- in- transit rates for both grass and feed lot cattle have resulted in the fattening, locally, of thousands of range and outside cattle. The beef industry alone returns approximately $ 900,000 annually. There are several killing and manu-facturing plants located in Klamath Falls. Sheep. Approxinately 150,000 ewes are maintained in the Klamafh Basin with an average annual output of about three- quarters of a million dollars.

There are now about 8,000 milk cows in the district. Klamath Falls, with its large industrial popu-lation, furnishes a good market for milk, butter, and cheese. Two local cooperative cheese manufacturing plants and four privately owned creameries operate in the district. The value of the dairy industry is approximately $ 600,000 annually. Local dairy prices for butterfat are maintained at l> e to 2 cents above the State average cwing to the favored position of the project-- half- way between Portland and Sun Francisco. This district offers many opportunities for increased dairying production, as costs are compara-tively low and climatic conditions are favorable.
