Riffe Lake, historically known as Mossyrock Lake then as Davisson Lake, is a reservoir formed by Mossyrock Dam. It is a popular water for smallmouth bass. The lake stretches more than 13 miles along US-12 east of Mossyrock and has a year-round open fishing season.
Riffe provides good fishing for landlocked coho and Chinook salmon, plus an occasional large brown trout. Rainbow and cutthroat trout are also available. Landlocked salmon rules apply. Other warm water species present include brown bullheads, along with a few bluegill and crappie. There are no Kokanee in Riffe Lake.
Mossyrock Park, near the west end on the south side of the dam, has camping facilities that can be reserved by calling (360) 983-3900. Mossyrock Park boat launch remains useable during most low-water conditions. Boat launches at the east end (Kosmos and Taidnapam Park) are not usable during low-water periods.
Bank access is available on both sides near the dam and at the Taidnapam Park "fishing bridge" near the upper end of the lake. Call the Tacoma Power toll-free fishing hotline at (888) 502-8690 to check reservoir levels.
