Lake Merwin

Lake Merwin is a reservoir in Washington surrounded by forested shores and fed by multiple tributaries. The water body serves purposes ranging from hydroelectric power generation to recreational boating and fishing activities.

The reservoir was created by dam construction in the mid-20th century to harness the region's hydroelectric potential. This project transformed the landscape and created a new recreational area for the surrounding communities.

The reservoir is accessible from multiple points along its shore, with some areas offering public boat launches and docks. Water conditions and temperatures vary by season, so checking conditions beforehand helps plan your visit.

The reservoir supports a diverse fish population including rainbow and cutthroat trout, making it a destination for fishing enthusiasts. The surrounding landscape has become an important habitat for wildlife, particularly waterfowl and other species.
