Facilities
Gerber Dam/Reservoir
Gerber Dam and Reservoir, on Miller Creek 14 miles east of Bonanza, Oregon, provides storage for irrigation and reduces flow into the reclaimed portions of Tule Lake and the restricted Tule Lake Sumps in the Tulelake National Wildlife Refuge. The dam, a concrete arch structure, has a height of 84.5 feet and a crest length of 460 feet. Reservoir capacity is 94,300 acre-feet.
Clear Lake Dam/Reservoir
Clear Lake Dam and Reservoir on the Lost River in California, about 19 miles southeast of Malin, Oregon, provide storage for irrigation and reduce flow into the reclaimed portion of Tule Lake and the restricted Tule Lake Sumps in Tulelake National Wildlife Refuge. The dam is a roller compacted concrete structure with a height of 42 feet and a crest length of 840 feet. The reservoir has a capacity of 527,000 acre-feet.
Anderson Rose Dam
Anderson-Rose Diversion Dam (formerly Lower Lost River Diversion Dam), on Lost River about 3 miles southeast of Merrill, Oregon, diverts water to serve the lands reclaimed from the bed of Tule Lake. The dam is a reinforced concrete slab and buttress structure with a height of 23 feet and a crest length of 324 feet.
Lost River Diversion Dam and Wilson Dam/Reservoir
Lost River Diversion Dam (Also known as Wilson Dam or Horseshoe Dam) is on Lost River about 4 miles below Olene, Oregon. The dam diverts excess water to the Klamath River through the Lost River Diversion Channel and restrains downstream flow in Lost River to control or restrict flooding of the reclaimed portions of the Tule Lake bed and to regulate the flow into the restricted sumps of the Tulelake National Wildlife Refuge. It is a horseshoe shaped multiple-arch concrete structure with earth embankment wings. The structural height is 42 feet and crest length is 675 feet.
Link River Dam
Link River Dam on Link River at the head of Klamath River and just west of Klamath Falls, Oregon, regulates flow from Upper Klamath Lake Reservoir. This reservoir is a principal source of water for the project. The dam is a reinforced concrete slab structure with a height of 22 feet and a crest length of 435 feet. The reservoir has a capacity of 873,000 acre-feet and is operated by the Pacific Power and Light Company, subject to Klamath Project rights.
A Canal Fish Screen
This $11.5 MM facility was a fast track project with the majority of the structural work taking place during the winter months in Klamath Falls, Oregon. Work included the design and construction of a cofferdam that isolated the work area from Klamath Lake, design and construction of temporary dewatering system connected to permanent power with a diesel powered backup system, demolition of the existing headgate structure and excavation of 50,000 cy. It also included placement of 6,000 cy of structural concrete in three months, the installation, startup, and testing of trash racks and a bracket green trash rake.
This job also included the supply and installation of bulkheads and embeds, structural steel and grating for “V” screen, primary and secondary fish screen panels and baffles, primary and secondary screen cleaners, and large electrically actuated gates, including a custom ramp gate. The construction of the pumping plant included two 20” fish pumps, supply and installation of 2,000 LF of fish pipe, construction of a fish evaluation facility, and installation of a power distribution system including a diesel standby generator. This project was completed on-time by the spring deadline to provide irrigation to more than 200,000 acres of farmland.
Malone Diversion Dam
Malone Diversion Dam, on Lost River about 11 miles downstream from Clear Lake Dam, diverts water to serve lands in Langell Valley. This dam, an earth embankment with a concrete gate structure, has a height of 32 feet and a crest length of 515 feet.
Klamath Straits Drain
Work on increasing this drain`s capacity from 300 to 600 cubic feet per second was completed in 1981. The drain conveys drainage water from Lower Klamath National Wildlife Refuge and from irrigated land which has been reclaimed from Lower Klamath Lake. The drain extends from the State Line Road approximately 20 miles north-westerly to Klamath River. The drain removes the excess winter flows and the drainage from the lower closed basin to the Klamath River.
Miller Diverson Dam
Miller Diversion Dam, on Miller Creek 8 miles below Gerber Dam, diverts water to serve lands in Langell Valley. The dam is a concrete weir, removable crest, and earth embankment wing structure with a height of 10 feet and a crest length of 290 feet.
Tule Lake Tunnel
Tule Lake Tunnel, a concrete-lined structure 6,600 feet in length with a capacity of 250 cubic feet per second, conveys drainage water from Tule Lake restricted sumps to Lower Klamath Lake.
`A` Canal Tunnel
This 3,300-foot tunnel, a part of the `A` Canal, has a capacity of 1,150 cubic feet per second and conveys irrigation water from Upper Klamath Lake to serve approximately 63,000 acres.
