Summit Lake is a 43-acre (170,000 m²) cold water reservoir located in Greenbrier County, West Virginia in the Gauley Ranger District of the Monongahela National Forest. The reservoir is formed by the impoundment of the waters of two forks of Coats Run, a small tributary of the North Fork of the Cherry River. There have been attempts to rename the lake in honor of Carl E. Gainer, a politician from nearby Richwood.
