About the Aquatic Reserve

Lake Kapowsin is a 512-acre low elevation lake in eastern Pierce County and is the Washington Department of Natural Resources' first freshwater aquatic reserve. The lush vegetated shorelines of Lake Kapowsin and plentiful natural habitat make Lake Kapowsin a popular hunting, fishing and boating destination. In addition, the lake has a unique origin story and geologic legacy.

Species and Habitats

Lake Kapowsin was created 500 years ago when the Electron Mudflow rushed down the Puyallup Valley from Mt. Rainier and dammed Kapowsin Creek flooding the valley floor and drowning the native forest. Tree stumps from this ancient forest remain in the lake today and provide valuable habitat for fish, birds, amphibians and invertebrates. 
 
Extensive shrub and emergent wetlands at the north and south ends of the lake and fringing wetlands along the shoreline provide habitat for many small mammals and amphibians.
 
The lake supports a range of native and stocked sport fish, including coho salmon, steelhead, cutthroat salmon, rainbow trout, largemouth bass, yellow perch, rock bass, black crappie, bluegill, pumpkinseed sunfish, walleye, and bullhead catfish.
