The objective of this inventory and tool is to build a community of practice among resource managers and enable them to identify high priority aquatic connectivity restoration projects. The prioritization tool allows users to explore and download barrier inventory information at different scales. The project tracks dams (including diversions, weirs, low head dams), assessed road stream crossings, and waterfalls. They do not track beaver dams or other non-structural barriers at this time. This inventory is compiled from multiple sources at multiple scales. The objective of this inventory is to highlight the efforts of states and local partners by compiling information and readily updating it from living sources of truth on a regular basis. Within the tool, a user can prioritize dams, assessed road stream crossings, or both barrier types together. A priority barrier to remove would be one that reconnects high quality habitat. For this reason, we calculate and use four metrics for each barrier:Miles restored by the potential removal of the structurePercent natural land cover within the floodplain of the structure's upstream networkThe percent of the upstream network that is altered by canals and ditchingThe complexity of the upstream network (number of stream size classes)These four metrics can be combined into three scenarios: network length, watershed condition, andcombined network length and watershed condition</DIV></DIV></DIV> North Atlantic Aquatic Connectivity Collaborative database: http://streamcontinuity.org.
