Minor Porter Log HomeLLELA was created in the early 1990's when the U.S. Army Corps of Engineers founded a consortium to manage nearly 2,000 acres below Lewisville Dam. Today the LLELA consortium includes the Corps, the University of North Texas, the City of Lewisville, the Lewisville Independent School District, the University of Texas at Arlington, and Texas A&M University. Our mission is to preserve and restore our native ecosystems and to provide and promote environmental education and scientific research.

LLELA Nature Preserve contains a variety of habitats, including prairies, bottomland hardwood forests, wetlands, and cross timbers forest. With such a diversity of habitats, there is a profusion of wildlife here. Mammals such as bobcats, white-tailed deer, and mink can be found, along with birds such as wild turkeys, painted buntings, and dozens of waterfowl species. LLELA is dotted with sloughs, wetlands, creeks, and dry channels, the landscape features originally wrought by the Elm Fork of the Trinity River and its tributaries during flood events. These remain filled by rainwater and flooding, providing areas where one can find wood ducks and other waterfowl, as well as many turtles, wading birds, and amphibians.
