Lake Ray Hubbard

The Town of Sunnyvale borders the southeastern edge of Lake Ray Hubbard.  This lake lies on the East Fork of the Trinity River, bisected by Interstate Highway 30, just east of Dallas in Collin, Rockwall and Dallas counties. 

Lake Ray Hubbard was built for municipal water supply but also features a lakeside power generating plant.  Much of the north end retains its original standing timber.  Shoreline areas have some vegetation.  The water is fairly turbid, rather fertile, and a maximum of 40 feet deep.
