Snow Lake, a glacier-dammed lake in the Kenai Mountains, released on September 16th. The draining of the lake caused the Snow River, Kenai Lake, and the Kenai River to rise significantly. Flow measured on the Snow River was measured to be about 15 times the normal flow expected for September. Snow glacier-dammed lake typically releases every 2 years, usually during the fall.
