where are the headwaters of the colorado river in texas
Colorado River (Texas) The Colorado River originates south of Lubbock, on the Llano Estacado, near Lamesa. It flows generally southeast, out of the Llano Estacado and through the Texas Hill Country, 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, 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. The Texas waterway is not connected to, nor part of, the longer and more well-known Colorado River that originates in Colorado, flows through Utah and Nevada, created the Grand Canyon and Lake Mead, and marks the entire length of the state line separating Arizona and California.
Rio Grande The Rio Grande rises in the western part of the Rio Grande National Forest in the U.S. state of Colorado. The river is formed by the joining of several streams at the base of Canby Mountain in the San Juan Mountains, just east of the Continental Divide. From there, it flows through the San Luis Valley, then south into the Middle Rio Grande Valley in New Mexico, passing through the Rio Grande Gorge near Taos, then toward Española, and picking up additional water from the San Juan-Chama Diversion Project from the Rio Chama. It then continues on a southerly route through the desert cities of Albuquerque and Las Cruces to El Paso, Texas, and Ciudad Juárez, Chihuahua. In the Albuquerque area, the river flows past a number of historic Pueblo villages, including Sandia Pueblo and Isleta Pueblo. Below El Paso, it serves as part of the border between the United States and Mexico.
