Aquatic Organism Passage and the Rehabilitation of High Hazard Potential Dams

Dams can pose an impediment to up and downstream migration for aquatic organisms and result in population declines. An aquatic connectivity decision framework can help dam owners decide between repairing or removing a high hazard potential dam, while also potentially leveraging additional resources for such activities. This fact sheet provides an example flowchart and other information to aid dam owners in project planning.
