Advantages of construction of dams
- Recreation
Dams provide prime recreational facilities throughout the United States. Boating, skiing, camping, picnic areas, and boat launch facilities are all supported by dams.
- Flood Control
In addition to helping farmers, dams help prevent the loss of life and property caused by flooding. Flood control dams impound floodwaters and then either release them under control to the river below the dam or store or divert the water for other uses. For centuries, people have built dams to help control devastating floods.
- Water Storage
Dams create reservoirs throughout the United States that supply water for many uses, including industrial, municipal, and agricultural.
- Irrigation
Ten percent of American cropland is irrigated using water stored behind dams. Thousands of jobs are tied to producing crops grown with irrigated water.

Because the water stored behind a dam in a reservoir is fresh, we can use it as a source of drinking water for nearby towns and cities.
