Blue Mountain Lake is a 2,910-acre impoundment of the Petit Jean River located in Yell and Logan Counties, Arkansas. Created in 1947 by the U.S. Army Corps of Engineers, this reservoir serves primarily for flood control and features significant annual water level fluctuations. With an average depth of 8.6 feet and a maximum depth of 30 feet near the dam, Blue Mountain Lake offers diverse fishing opportunities throughout the year. The lake's unique geography gives it characteristics of both highland and lowland reservoirs, creating a varied habitat for numerous game fish species. Fishing is typically best during spring and fall, with crappie being the favorite catch among local anglers.
