Artificial lakes
The East Fork of the Trinity River rises in Grayson County, then flows south for 80 miles through Collin, Rockwall and Dallas County to the confluence with the Main Stem in Kaufman County, southeast of Dallas.
Much of the East Fork Trinity has been dammed by Lake Lavon and Lake Ray Hubbard.
The East Fork flows through heavily wooded bottomland hardwood forests of Elm, Ash, Cottonwood, Willow, Post Oak and Pecan.
Flow in the East Fork is dependent upon dam releases from Lake Lavon and Lake Ray Hubbard or recent heavy rainfall.
