Aquatic Organism Passage and the Rehabilitation of High Hazard Potential Dams

This fact sheet provides dam owners with a decision framework for evaluating aquatic organism passage when considering the rehabilitation or removal of high hazard potential dams. It explains the ecological impacts of dams on aquatic connectivity and outlines a flowchart to guide project planning, including coordination with conservation agencies and prioritization based on species and habitat needs. The document emphasizes the mutual benefits of dam removal for both safety and environmental restoration, particularly in geographic priority areas for aquatic species conservation.
