Lock and Dam No. 4 is one of five navigation lock and dam structures that comprise the J. Bennett Johnson Waterway on the Red River, and one of three that will be developed to add FishSafe™ power generation.
Lock and Dam No. 4 was designed and constructed under the direction of the U.S. Army Corps of Engineers. The principal structures associated with Lock and Dam No. 3 are a 26- by 239-m (84- by 785-ft) navigation lock, a gated spillway containing five tainter gates, and a hinged crest gate 30 m (100 ft) wide. The project will be developed using Natel’s FishSafe™ RHT designs and will generate an estimated total of 20 MW of electricity.
