This online database (https://www.streamcontinuity.org/cdb2/naacc_search_crossing.cfm) serves as a common repository for road-stream crossing assessment data assembled by the North Atlantic Aquatic Connectivity Collaborative (NAACC). Both a network of partners and a source of shared resources, the NAACC offers a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities. The NAACC offers training in standard protocols for conducting assessments, online tools for prioritizing upgrades based on ecological benefits, and this database...

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.The link address...
