Coldwater Lake is unique because it is a barrier lake, meaning it was formed directly by the 1980 eruption of Mount St. Helens. The massive debris avalanche from the eruption dammed Coldwater Creek, creating the lake over several months. Its relatively recent and dramatic formation, along with the ongoing ecological recovery, makes it a living laboratory for geological and biological study.
While the lake is beautiful, swimming is generally not recommended due to cold temperatures and potential hazards. However, the lake is popular for non-motorized boating activities such as kayaking, stand-up paddleboarding, and canoeing. Only non-combustion engines are permitted on the lake.
