Wheeler Lake is located in the northern part of the state of Alabama in the United States, between Rogersville and Huntsville. Created by Wheeler Dam along the Tennessee River, it stretches 60 mi from Wheeler Dam to Guntersville Dam. It is Alabama's second largest lake at 68,300 acre, and only a few hundred acres smaller than the largest lake in Alabama, Guntersville Lake, which is 69,100 acre and is separated by the Guntersville dam from the lake. Decatur operates the busiest port along the Tennessee River on this lake, Port of Decatur. Wheeler Lake is a major recreation and tourist center, attracting about four million visits a year. Along with camping, boating, and fishing, visitors enjoy the Wheeler National Wildlife Refuge several miles upstream from the dam. The lake and dam are named for General Joseph "Joe" Wheeler.
