Summary

This USGS data release includes a comma separated value (CSV) file that contains 19 reach-based dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous United States. Dam metrics fall into three main categories: count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using spatially verified large dam locations (n=49,140) primarily from the National Anthropogenic Barrier Dataset (NABD) 2012 that were spatially linked to the National Hydrography Dataset Plus version 2.1 (NHDPlusV2.1). These dam metrics have been summarized using the unique identifier field native to the NHDPlusV2.1 (COMID) which can be used to [...]

Purpose

These metrics were developed for multiple reasons. They were initially developed on the NHDPlusV1 (https://doi.org/10.5066/F7FN14C5) 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). This effort used the same process to support ongoing efforts on the NHDPlusV2.1 spatial framework. These metrics can also be used to characterize regional variation in dam influences on stream habitats and fish assemblages. They also 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. Last, these data support distribution modeling of fluvial fishes.
