Building Back Together: Partnering with The Nature Conservancy to Restore Headwater Streams by Removing Dams and Restoring Stream Channels

Dams alter river ecosystems on a global scale; more than 50% of all major river systems are impounded by dams. In Georgia, rivers are dissected by more than 30,000 dams. These dams sever connectivity among rivers segments, fragmenting once contiguous stream ecosystems. This presentation describes a collaborative partnership between scientists at The Nature Conservancy and students/faculty at Columbus State University. The partnership’s goals included 1) removing 2 earthen dams and restoring their stream channels, and 2) evaluating the efficacy of these restoration efforts using biological and chemical indicators. Our results are consistent with the premise that complete ecosystem recovery requires full restoration of a stream’s riparian tree canopy.
