Description:

The main objective of this project was to develop a dataset of large, anthropogenic barriers that are spatially linked to the National Hydrography Dataset Plus Version 1 (NHDPlusV1) for the conterminous U.S. and the high resolution National Hydrography Dataset (NHD) for Alaska (1:63,000 scale) and Hawaii (1:24,000 scale) to facilitate GIS analyses based on the NHDPlusV1/NHD and NID datasets. To meet this objective, Michigan State University conducted a spatial linkage of the point dataset of the 2009 National Inventory of Dams (NID) created by the U.S. Army Corps of Engineers (USACE) to the NHDPlusV1/NHD. The pool of dam data included were modified based on 1) dam removals that occurred after development of the 2009 NID and 2) the identification of duplicate dam records along state boundaries (cases where more than one state reported the same dam). The US Geological Survey (USGS) Aquatic GAP Program supported this work.
Dams spatially linked to the NHDPlus/NHD offer an advantage to datasets of dams not linked to the NHDPlusV1/NHD because dams represented by points are located on flowlines representing stream and reservoir waterbodies. These qualities will allow managers and researchers to perform analyses and make more informed decisions when stream connectivity is considered in management plans and/or research projects. This will be the first spatially accurate dataset of its size and extent to be available for wide-spread use.
