Road Stream Crossing Upgrade Effects, Northeast U.S.

This dataset is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This dataset represents the relative potential to improve local aquatic connectivity by upgrading road-stream crossings. The model incorporates survey data from the North Atlantic Aquatic Connectivity Collaborative (NAACC). To view the current NAACC database go to https://streamcontinuity.org/database.htm. The Road Stream Crossing Upgrade Effects dataset and other datasets that augment or complement aquatic connectivity are...

Dam Metrics Representing Stream Fragmentation and Flow Alteration for the Conterminous United States Linked to the NHDPLUSV1

This CSV file contains 21 dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous USA. Dam metrics fall into four main categories: segment-based, count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using spatially verified large dam locations (n=49,468) primarily from the National Anthropogenic Barrier Dataset (NABD) that were spatially linked to the National Hydrography Dataset Plus version 1 (NHDPlusV1). These dam metrics have been summarized using the unique identifier field native to the NHDPlusV1 (COMID) which can be used to join this table to spatial layers and data tables of the...
