Lake Lavon

Because Life is Better at the Lake

Lake Lavon Information

Started in 1948 and completed in 1953, the Lavon Dam was created to impound the upstream East Fork of the Trinity River, some of its tributaries, and the areas immediately surrounding them. The reservoir was primarily designed for preventing seasonal flooding of rich bottomland in northeastern Collin County, and water storage. Its construction also stimulated land development along the shores of the lake and recreational use of the water and adjacent land areas. In 1962, Congressional approval was given to modify the project to increase storage for water supply because of the growing water supply need of the area. Also part of the modification was to add recreation as a purpose for the lake.
