CRP Photo Gallery - The Upper Rio Grande SubBasin

The upper Rio Grande sub-basin extends from the Texas-New Mexico state line downstream to the International Amistad Dam, a length of 650 miles (1,045 km). The water in the upper portion of this segment is used for agriculture and as a drinking water supply. Water in the river downstream of El Paso and Juarez is primarily composed of agricultural return fl ows, wastewater effl uent, and raw or partially treated sewage, and is therefore high in salts and bacteria. Further downstream, two major tributaries (the Rio Conchos from Mexico and the Pecos River in Texas) join the Rio Grande, increasing water quality and quantity. Between those tributaries is the wild and scenic Big Bend region. The upper Rio Grande sub-basin ends at Amistad International Dam.
