Summary

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 NHDPlusV1. Non-fluvial [...]

Purpose

These metrics were developed for multiple reasons. First, they were developed to improve dam-related measures in support of conducting the 2015 condition assessment of fish habitat in fluvial waterbodies throughout the conterminous United States in support of the National Fish Habitat Partnership (NFHP). Second, these metrics can be used to characterize regional variation in dam influences on stream habitats and fish assemblages. Lastly, these data have broad utility beyond the study of fishes, as habitat alteration by dams is known to affect many additional groups of organisms reliant upon riverine environments, including macroinvertebrates, reptiles, amphibians, birds, mammals, and plants.
