Douglas Dam is a hydroelectric dam on the French Broad River in Sevier County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in record time in the early 1940s to meet emergency energy demands at the height of World War II. Douglas Dam is a straight reinforced concrete gravity-type dam 1705 feet (520 m) long and 202 feet (62 m) high, impounding the 28,420-acre (11,500 ha) Douglas Lake. The dam was named for Douglas Bluff, a cliff overlooking the dam site prior to construction.

One of the purposes for the Douglas Dam and Douglas Lake are for recreational boating, swimming, and fishing. Significant amounts of freshwater fish are caught in Douglas Lake as part of the food supply for human beings. Douglas Lake has an average of 500 miles (800 km) of shoreline, and it has an average surface area of nearly 30,000 acres (120 square kilometers), with both measurements varying according to the seasonally-changing water level of Douglas Lake.

Douglas Lake is the recreational destination for up to two million visitors per year. Primary uses of the lake and its shores are fishing, boating, water skiing, swimming, camping, hiking, and wildlife observing. In addition to a number of private campgrounds in this area, TVA provides the Douglas Dam Headwater Campground and the Douglas Dam Tailwater Campground for public use. The Tennessee Wildlife Resources Agency stocks Douglas Lake tens of thousands of sauger and crappie fish each year to thrive and then provide recreational and food fishing.
