Bureau of Reclamation Year: 1958, 2008, 2006 INTRODUCTION AND GENERAL Genex*al 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 Comity, 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 3&>^00, 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 warmest month is 630 F. The coldest month has raez.n 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 U,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. In 1958 the project provided irrigation service to 21^,500 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. DTERODUCTIOH AND GBNKRAL (Continued) General Description of the Project (Cont.) Upper Klamath Lake on the Klamath River is the principal storage reservoir, having an active capacity of 52^,800 acre-feet. It is controlled by Link River Dam constructed, maintained, and operated 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 Creel; 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*b3OO 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 darn and main canals for the Langell Valley Division; and drainage outlets for the Lower Klamath and Tule Lake Divisions?
