Evaluation of Fish Facilities and Passage at Foster and Green Peter Dams on the South Santiam River Drainage in Oregon
Abstract
The U. S. Army Corps of Engineers completed construction of the Green Peter-Foster project in the spring of 1969. Green Peter Dam began impounding water in October 1966 and Foster Dam began in December 1966. Prior to impoundment, the Oregon Game Commission using Corps funds, chemically treated the reservoir areas and the tributary streams above both dams to control undesirable species of fish. Spring chinook and winter steelhead are indigenous to the South Santiam system above Lebanon, Oregon. Coho, sockeye, and summer steelhead were introduced in 1961, 1967, and 1969, respectively. Provisions at the project for evaluating anadromous fish runs consist of adult handling and counting facilities at both dams and a special downstream-migrant collection and counting facility at Green Peter Dam. No provisions were made for counting or handling downstream migrants at Foster Dam. Juvenile fish must pass through the spillway or turbines at that dam. Subsequent to construction of Green Peter and Foster dams, Pacific Power and Light Company agreed to deactivate their turbines on the unscreened Lebanon Canal during the November-June downstream migration period of hatchery and wild anadromous salmonids. From July 1967 through October 1971, the Fish Commission of Oregon conducted an evaluation study designed to determine the efficiency of the fish passage facilities. 1he study was financed by the Corps and supervised by a steering committee composed of one member each from the Corps of Engineers, Fish Commission of Oregon, Oregon Game Commission, Bureau of Sport l:isheries and Wildlife, and the National Marine Fisheries Service.
