Description of Dams and Other Barriers as a Human Activity Affecting Fish Habitat in Southeast Atlantic States

from the National Fish Habitat Partnership's 2015 Through a Fish's Eye Report


Over 10,000 dams impound rivers and streams in the three Southeast Atlantic states. North Carolina has over 5,600 dams and barriers on 17,000 stream miles, many of which are old and obsolete structures. There is an average of one barrier structure every three miles.
