The Rio Grande and Colorado Rivers; What is the eventual final discharge volume of these rivers? Wh

Mostly due to dams, the discharge is lower at the very end for these rivers. Other factors include other forms of human interference like farm irrigation.

Diversion of water from CO river has caused fighting between CA, UT, NV, AZ, NM and Mexico. Boulder dam and Glen Canyon Dam – Block fish passage/spawning – Trap nutrient-rich silt – Alter water temperatures Farm irrigation has caused salts from naturally alkaline soils to leach into river Millions of acres of farmland are “salt-poisoned” due to irrigation using increasingly salty water. What’s left for Mexico> CO River delta in Mexico (once lush, agriculturally productive) no longer receives the natural flow of silt and nutrient-rich water. The salinity of the CO River was so high during the 1960s that Mexico-U.S. agreed to build a desalination plant to restore the salinity of the CO to useable levels.
