Denison Dam
History
Completed in 1943 primarily as a flood control project, it was at the time the "largest rolled-earth fill dam in the world". Only five times has the lake reached the dam's spillway at a height of 640 feet (200 m) above sea level: 1957, 1990, 2007, and twice in 2015. It takes its name from Denison, Texas, just downriver from the damface.
Denison Dam contains a total of 18.8 million cubic yards (14,000,000 m³) of rolled-earth fill. It produces roughly 250,000 megawatt hours of electricity per year, while Lake Texoma provides nearly 125,000 acre-feet (154,000,000 m) of water storage for local communities under five permanent contracts.
In addition to two federally managed wildlife-refuge areas, Denison Dam has made possible 47 recreational areas managed by the U.S. Army Corps of Engineers, two state parks -- one in Oklahoma and one in Texas -- as well as 80,000 acres (32,000 ha) of open public land used for hunting.
[...] General Lucius D. Clay was the principal manager of the project.
Oklahoma State Highway 91 and, to a lesser extent, Texas State Highway 91 cross over the dam.
