Description: This dataset is the national output of dams from the Aquatic Barrier Prioritization Tool (aquaticbarriers.org). This dataset is a compilation of dams from across the country from both living and static sources. Dams are updated from living sources 4X per year into a master feature service which is available for QAQC and social feasibility analysis. This master then is downloaded and run through several scripts in a connectivity analysis (GitHub - astutespruce/sarp-connectivity: Southeast Aquatic Barrier Prioritization Tool) to produce indicators for prioritization at aquaticbarriers.org. This is the output of the latest analysis 3.13.0; 10/17/2024. Data is incomplete while this project is ongoing. New dams are discovered every day. Data and prioritization maintained by the Southeast Aquatic Resources Partnership.
