Blakely Mountain Dam impounds the waters of the Ouachita River near Hot Springs to create Lake Ouachita, the largest lake (40,100 acres) located entirely within the state of Arkansas. The dam construction was finished in the spring of 1953 and power was first placed on the line in August 1955.
Surrounded by the Ouachita National Forest, the Ouachita is one of Arkansas's most beautiful lakes. The 40-mile-long lake is a favorite of sailors for its vast stretches of open water. Recreational boating is also very popular on Lake Ouachita, which boasts over 100 uninhabited islands and has a wilderness shoreline of some 970 miles.
The lake boasts an unusual feature, the Geo-Float Trail (created by the U.S. Army Corps of Engineers) is a marked route which can be followed by boaters guided by a brochure which details prominent geologic features along the route.
This lake has a lot of small fingers and estuaries which to explore and anchor in. With all of these and the many islands, a trailer sailor could easily spend a week on the lake and never see or anchor in the same place twice.
