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.

Bureau of Reclamation Year: 1957, 2008, 2006 INTRODUCTION AND GENERAL General Description of the Project Location. The Klamath Project is in the Upper Klamath River Basin, east of the Cascade Range. 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. It is controlled by Link River Dam constructed, maintained, and operated INTRODUCTION AND GENERAL (Continued) General Description of the Project (Cont.) by The California Oregon Power Company under an agreement with the project whereby irrigation requirements and rights are protected. The Main, Lower Klamath, and Tule Lake Divisions are served from this source, Gerber Reservoir on Miller Creek and Clear Lake Reservoir on Lost River provide flood control for the Tule Lake Division and an irrigation supply for the Langell Valley Division. Their active storage capacities are 9*^300 acre-feet and 513*300 acre-feet, respectively. Federally-financed project works also include the diversion, distribution, and drainage systems for the Main and Tule Lake Divisions; the diversion dam and main canals for the Langell Valley Division; and drainage outlets for the Lower Klamath and Tule Lake Divisions.
