Customizable map tool for aquatic barrier prioritization

This tool allows users to view aquatic barriers (dams, road-stream crossings) by the relative gain in ecological value if they were removed. Users start with a consensus map of anadromous fish priorities, which was developed based on stakeholder input as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC). Beyond the consensus results, interested users can create their own scenarios by filtering input barriers to limit the analysis to a given state or watershed, changing the weights of metrics according to their importance to the analysis objectives (e.g. length of upstream network connected, number of diadromous fish present, etc.) and by modeling the removal of up to 10 barriers.
