About the lake
Haven Lake in Mason County, Washington, is a 69.5-acre lowland lake sitting at about 370 feet elevation with depths up to 31 feet. Known for its heavy spring rainbow trout stocking, it also holds coho salmon, pumpkinseed sunfish, largemouth bass, and the occasional pickerel or carp. Access is via a single gravel boat ramp—ideal for small boats—with basic parking and ADA-accessible restrooms but no developed shoreline fishing areas.
