Hydropower and Invasive Species

USGS interdisciplinary science directly addresses a variety of threats to hydroelectric dams by addressing damage caused by invasive species such as a variety of mussels that clog hydroelectric facilities and damage aquatic ecosystems. One important benefit of this USGS science is that it can help prevent unnecessary maintenance costs.
