Lavon Lake is a freshwater reservoir located in southeast Collin County, Texas, on the East Fork of the Trinity River near Wylie, off State Highway 78.

In addition to flood control and recreation,[2] the lake serves as a water source for hundreds of thousands of North Texas residents.

[3] [4] 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.

This focused management and development for public use, recreational activities, and stewardship of the water and land areas.
