Lake Lewisville is a large reservoir located in North Texas that was created in the 1950s by the construction of the Lewisville Dam on the Elm Fork of the Trinity River. The lake is a popular destination for boating, fishing, and other recreational activities, and it also serves as a vital source of water for the surrounding communities.

In the early years of the lake's existence, little attention was paid to conservation efforts, and the U.S. Army Corps of Engineers, which manages the lake, focused primarily on flood control and hydropower generation. However, as the population of the region grew and the demand for water increased, the Corps began to place a greater emphasis on water conservation.
