Flood Risk Management
In 1927, the Lower Mississippi Valley was literally swamped by one of the worst floods on record, and the Vicksburg District of the U.S. Army Corps of Engineers was caught in the middle. Much of the land along the Mississippi and its tributaries was protected by levees, and only by levees. Following the 1927 Flood, it was realized that, while levees were indispensable, to depend on them for flood protection was suicidal. With the Flood Control Act of 1928, the district became involved in a comprehensive flood control program, which eventually included Arkabutla, Sardis, Enid, and Grenada lakes.
Construction of Enid Dam started February 1, 1947, and the lake was placed in operation in December 1952. The total cost of the project, including lands, highway and utility relocation, was approximately $15,000,000. When filled to the spillway crest, the lake extends up the Yocona River Valley a distance of over 18 miles, with a surface area of approximately 28,000 acres and 220 miles of shoreline. In 2002, Enid Lake celebrated its 50th Anniversary.
Enid Lake is operated on a Rule Curve for filling and lowering the lake. Daily Pool Stages are taken and are published on the District web page.
