The Colorado River is a river that runs through Texas; it should not be confused with the much longer Colorado River which flows from Colorado into the Gulf of California. The Colorado River originates south of Lubbock, on the Llano Estacado, near Lamesa. It flows generally southeast, out of the Llano Estacado and through several reservoirs including Lake J.B. Thomas, E.V. Spence Reservoir, and Lake O.H. Ivie. The river flows through several more reservoirs before reaching Austin TX, including Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson, commonly referred to as Lake LBJ, and Lake Travis. The Llano River joins the Colorado at Lake LBJ, near Kingsland. The Pedernales River joins the Colorado at Lake Travis near Briarcliff. After passing through Austin, the Colorado River continues flowing southeast until emptying into Matagorda Bay on the Gulf of Mexico, near Matagorda.
