Lake Ouachita is a lake created by the damming of the Ouachita River by Blakely Mountain Dam. The lake is located near Hot Springs, Arkansas. Lake Ouachita is the largest lake completely in Arkansas, as the larger Bull Shoals Lake extends into Missouri. Lake Ouachita has over 690 miles (1,110 km) of shoreline and over 40,000 acres (16,000 ha) of water. It is completely surrounded by the Ouachita National Forest. Lake Ouachita is located near two other lakes, Lake Hamilton and Lake Catherine. These three lakes, DeGray Lake to the near south, and the thermal springs of Hot Springs National Park make Hot Springs a popular tourist getaway.

Lake Ouachita also features one of the largest crystal veins in the world. Lake Ouachita has rare jellyfish (non-stinging) and sponges found in only very few of the cleanest freshwater lakes.

Scuba divers from all over the world enjoy the underwater experience as well as the special spear fishing season. The original purpose of Lake Ouachita was flood control and hydroelectricity.
