River Dams
The study of the Snake River dams gives us a perfect example of how dam improvements can make a difference in the environment, as well as provide valuable knowledge that the rest of the world can apply to other dam projects.
It is interesting to note that civilizations have used dams as early as the Mesopotamian and Egyptian eras BCE. They used dams for flood control as well as to irrigate their crop fields.
According to Lt. Col. Vail, the study done by the U.S. Army Corps of Engineers on the four lower Snake River dams provides valuable data that is very important to take into consideration.
