Get hooked on kokanee

We began stocking kokanee in Alder Lake in 1999, although releases of kokanee historically took place at Alder Lake in the 1950s.
We study the fishery to learn how to make it more successful. Tacoma Power's fisheries staff collects information from Alder Lake anglers and performs spawning surveys of Alder Lake tributaries.
Salmon Habitat Enhancement
Before Alder Dam
and LaGrande Dam
were built, a natural barrier that is now beneath LaGrande reservoir prevented fish from migrating upstream. That means it wasn’t necessary to install fish ladders at the dams.
Tacoma Power releases water from LaGrande Dam into the Nisqually River to enhance the fish habitat downstream of the dam.
- Released flows are higher than naturally occurring flows in the summer and fall months.
- The flows create more spawning habitat for Chinook and coho salmon.
- The released water allows fish to distribute more broadly throughout the river, providing more habitats for fish to use.
In addition, Tacoma Power fully funds the operation of the Nisqually Tribe's Clear Creek Hatchery. This hatchery produces approximately four million Chinook smolts and one million coho smolts each year.
These plants result in adult returns to the hatchery of approximately 12,000 adult Chinook and up to 4,000 adult coho annually.
Warm Water Fishery
Alder Lake also provides exceptional angling opportunities for warm water species. Fish for largemouth bass, smallmouth bass, black crappie and yellow perch.
