Island Lake is open year-round for fishing. The lake is stocked in April and May with catchable-size (10"�-12"�) and some larger jumbo and triploid rainbow trout. Fingerling (4-5"�) rainbow trout stocked last fall will have fed in the lake and grown larger and also contribute quality fish to the fishery. The daily trout limit is 5 fish; no more than 2 over 14"� may be retained. The lake also provides fair fishing for largemouth and smallmouth bass and good fishing for yellow perch.
There is a state access with boat ramp and one toilet. See Washington State Parks website for ADA accessibility information.
