Gainesville Lake is a 6,400-acre reservoir located in west central Alabama, created by the Howell Heflin Lock and Dam on the Tombigbee River. The lake is part of the Tennessee-Tombigbee Waterway and offers opportunities for paddling, fishing, and other water-based recreation.

Access to the lake is available via ten public use areas, with eight providing boat launches suitable for canoes and kayaks. The Vienna Landing, located approximately 1.5 miles from the mouth of the Sipsey River, is one notable access point for paddlers.

Gainesville Lake is known for its largemouth bass and crappie fishing. The best paddling spots are typically found in the lake's sloughs and backwater coves, around standing timber, and near emergent and submersed aquatic plants. These areas not only provide scenic paddling routes but also offer good fishing opportunities.

The lake is surrounded by forests and wetlands, creating a scenic backdrop for paddlers. Wildlife viewing opportunities include various fish species, waterfowl, and potentially alligators in the nearby wetland areas.

Facilities at the recreation areas include picnic areas, shelters, and primitive camping sites. Some areas are wheelchair accessible. The U.S. Army Corps of Engineers manages the lake and its facilities.

Water quality in Gainesville Lake is generally good, supporting a diverse fish population. However, as with many reservoirs, water levels can fluctuate based on dam operations, so paddlers should be aware of changing conditions.

The lake's primary uses include navigation, flood control, and recreation. Paddlers should be cautious of commercial barge traffic on the main channel of the Tennessee-Tombigbee Waterway.

While specific seasonal patterns are not provided, the climate in this region typically allows for year-round paddling, with summers being hot and humid and winters mild.
