Even though dams can be a benefit to society, they can also cause a lot for harm to the rivers. Dams degraded river ecosystems, depleted fisheries, and diminished the recreational use of nearly all of the nation’s rivers. Many of the dams are unsafe, old or no longer serve their intended purposes.

Dams are used to generate hydropower by releasing the water to move the turbine that generates the power. Hydropower is a big industry in the United State it is responsible for most of the United States renewable energy resources. Dams are made for the water storage in areas where water is not easily accessible. The storing of water allows communities to have a reserve water supply in case of a drought or water shortage.
