The Rio Grande (known in Mexico as the Río Bravo) is a river that flows from Colorado in the United States to the Gulf of Mexico. Along the way it forms part of the border with Mexico. Its total length was 1,896 miles (3,051 km) in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is the fourth or fifth longest river in North America.

Silvery Minnow
The Rio grande Silvery Minnow is a small, silvery animal with fins and scales. It has small eyes. He rarely gets longer than 3.5 inches. It hatches from a floating egg. It eats algae and tiny plant pieces it finds floating in the water and on the river bottom. Sometimes it eats old insect skins. It usually travels in large groups called “schools.” He prefers slow-moving waters where the river meanders and braids. He releases his eggs when the river flow increases during the early spring to summer. He is considered an endangered species that lives in the Rio Grande.

New Mexico Water Rights
The United States and Mexico share the water of the river under a series of agreements administered by the International Boundary and Water commission. The most notable of these treaties was signed in 1906 and 1944. The IBWC today also allocates river waters between the two nations, and provides for flood control and water sanitation.
Use of that water belonging to the United States is regulated by the Rio Grande Compact, an interstate pact between Colorado, New Mexico, and Texas. The water of the Rio Grande is over-appropriated: that is, there are more users for the water than there is water in the river. Because of both drought and overuse, the section from El Paso downstream through Ojinaga was recently tagged "The Forgotten River" by those wishing to bring attention to the river's deteriorated condition.[15]
There are a number of dams on the Rio Grande, including Cochiti Dam, Elephant Butte Dam, Caballo Dam, Amistad Dam, Falcon Dam, Anzalduas Dam, and Retamal Dam. In southern New Mexico and the upper portion of the Texas border segment, the river's discharge dwindles. Diversions, mainly for agricultural irrigation, have increased the natural decrease in flow such that by the time the river reaches Presidio, Texas, there is little or no water. Below Presidio the Rio Conchos restores the flow of water.
