Rio Grande

Fifth Longest River In the USA

What is a watershed?

A watershed is an area of land that feeds all the water running under it and draining off of it into a body of water. It combines with other watersheds to form a network of rivers and streams that progressively drain into larger water areas.

Rio Grande watershed passes through

Colorado, New Mexico, Texas, and Mexico

The entire Rio Grande/ Rio Bravo watershed covers an area approximately 924,300 square kilometers (335,000 square miles), with approximately half the watershed in the United States and the other half in Mexico.

About

  • It extends from the San Juan Mountains of Colorado to the Gulf of Mexico (1,901 miles) and forms a 1,255 mile segment of the border between the United States and Mexico.
  • The Rio Grande is a major water supply for the border communities of Texas and for Mexico. It is projected that municipal use will increase by one-hundred percent over the next fifty years and industrial use will increase by forty percent
  • Also sometimes referred to as the “Rio Bravo”

Concerns

  • Brackish water (becoming more salty)

  • Water usage expected to double in the area in the next 50 year which affects availability of the water as the populations of both Mexico and America grow.
