Dam Relicensing

Dams block the upstream and downstream movement of fish. Here, sturgeon congregate at the base of a dam that is preventing them from swimming upstream to spawn.

The Federal Energy Regulatory Commission authorizes the initial construction of non-Federal hydropower projects (i.e., dam construction) and reconsiders licenses every 30 to 50 years. The U.S. Fish and Wildlife Service conducts environmental reviews during relicensing.

 

Although hydropower projects can be an important source of renewable energy, they also dramatically change the nature of rivers. Some of the impacts that result from dam construction and maintenance include changing the natural seasonal pattern of river flows, creating reservoirs, blocking fish passage, fragmenting river systems, and increasing streambank erosion.

 

Our environmental reviews result in license conditions that address those impacts and improve fish and wildlife habitat.
