DeGray Dam Visitor Center


In 1950, Congress authorized the U.S. Army Corps of Engineers to construct the multipurpose DeGray Lake Project. Construction began in 1963 and was completed in 1972 at a cost of $63.8 million. The main dam is of earthfill construction, rising 243 feet above the stream bed. About 6,831,000 cubic yards of material were used to build the embankment. On the downstream side of the dam, a 40,000 kw conventional hydraulic turbine and a 28,000 reversible turbine generate electricity for use in parts of Arkansas, Texas, and Oklahoma. The Visitor Center contains 2- and 3-D displays illustrating the dam's construction and operation.

Fun Fact:In addition to seeing the DeGray Dam, many visitors come here for the pleasure of sport fishing. One of the popular places to fish is in the lower lake created by the dam's continuous outflow. The water temperature is controlled through the use of baffle gates and bulkheads, which can be positioned to release water from three different elevations.
