Historical Context

Congress authorized construction and development of the Klamath Project (Project) in 1905. The Project was designed to convert a large proportion of the lakes and marshes of the Upper Klamath Basin to irrigated agricultural lands. To accomplish this, the BOR negotiated with California and Oregon to cede the land underlying Lower Klamath and Tule Lakes to the federal government and received approval from Congress to destroy the navigability of Lower Klamath and Tule Lakes by draining them. One hundred eighty five miles of main canals, 680 miles of lateral canals, and 728 miles of drain ditches with depths ranging from a few feet to 10 feet were subsequently constructed, effectively re-plumbing the Klamath Basin and by 1957, diverting 500,000 acre-feet of water to irrigated agriculture. Today the Project irrigates about 200,000 acres of land and provides water (when available) to about 86,000 acres of National Wildlife Refuge lands.
