Seattle Public Utilities provides funding and other support for the operation of the Cedar River Sockeye Hatchery. The hatchery is located near the Landsburg Dam on the Cedar River. SPU and the Washington Department of Fish and Wildlife (WDFW) have a cooperative agreement to operate the hatchery. Sockeye fry produced at the hatchery contribute to sockeye returns to the Cedar River and have made more frequent fisheries possible in Lake Washington.
To protect drinking water quality, sockeye are not allowed to pass the Landsburg Dam. As mitigation, the hatchery produces fry to replace those that could have been produced above the dam. Hatchery fry supplement production from sockeye spawning in the Cedar River below the dam.
The state-of-the-art hatchery has the capacity to hold over 4,000 adult sockeye for broodstock and can produce up to 34 million sockeye fry. Broodstock collection occurs at river mile 1.7, in the Cedar River.
The hatchery has features that help produce fry as similar as possible to fry produced in the river.
