Klamath Project

The Klamath Project was developed by the United States Bureau of Reclamation to supply farmers with irrigation water and farmland in the Klamath Basin.

The two main sources supply water for the project are Upper Klamath Lake and the Klamath River. The main bodies of water in the Klamath Project are Clear Lake Reservoir, Klamath River, Link River, Lost River, Lower Klamath Lake, Tule Lake, and Upper Klamath Lake. The project fills these reservoirs from the spring runoff, peaking generally in March and April, and keeps the runoff from flooding the historical marshes that are a large portion of the present farmland. There are also many minor streams in the area.

225,000 acres (91,000 ha) of rangeland have been transformed into active farmland through the Klamath Project. 80,000 acres (32,000 ha) of this transformed land were under Lower Klamath Lake, a shallow marsh straddling the Oregon-California border between the California towns of Dorris and Tulelake. Tule Lake was also reduced in size by diverting water from Lost River to the Klamath River.

Farmers in the project raise barley, alfalfa hay, and other hay, oats, potatoes, and wheat.

The Klamath Basin is on the Pacific Flyway and the Klamath Basin National Wildlife Refuges Complex is visited by migratory game birds every year.
