Located south of Port Townsend this 70 acre lake is encompassed by Anderson Island State Park. It is one of the few lowland lakes in western Washington that yields a lake-reared Rainbow Trout fishery from fry plants as opposed to catchable sized plants. Carry overs from each spring fishery survive to their second season and provide opportunity to catch fish 2 to 3 pounds as well.
However, alge blooms on Anderson Lake have resulted in short spring seasons with closures by May. Each year the Jefferson County Health Department works with WDFW to determine algae levels and whether the lake will open on the last Saturday in April as the stated in the fishing pamphlet.
