Description: This dataset represents dam and road stream crossings in the northeastern United States (ME, NH, VT, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, DC). This data was complied as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC) for the 2016 version of the Northeast Aquatic Connectivity anlaysis (http://maps.freshwaternetwork.org/northeast). The road-stream crossing data in this dataset compiled by the NAACC (https://streamcontinuity.org/) and its contributors. Dam data was compiled for the original Northeast Aquatic Connectivity study (http://rcngrants.org/content/northeast-aquatic-connectivity) and revised based on input from the Northeast Aquatic Connectivity project workgroup, updates from state dam databases, and removals from American River's dam removal database (https://www.americanrivers.org/threats-solutions/restoring-damaged-rivers/dam-removal-map). Both road-stream crossings and dams were spatially linked to flowlines in the USGS National Hydrography Plus (NHD-Plus) v2 1:100,000 stream dataset. These barriers form the primary input dataset for the 2016 version of the Northeast Aquatic Connectvitiy analysis. (http://maps.freshwaternetwork.org/northeast). To this barrier dataset, 38 ecologically-relevant metrics were calculated and used in the barrier prioritization.
