Using a combination of tabular and spatial data queries, we identified 129,773 flowlines in the hydrological framework of the National Hydrography Dataset Plus Version 1 (NHDPlusV1) that were created due to breaks in flowlines resulting from flowline intersection with quadrangle map boundaries. We found instances of this occurring in all 18 processing units of the NHDPlusV1 dataset. To aid in managing for this characteristic of the NHDPlus, we developed this EcoReach table (nhdplusv1_ecoreachv2.0.csv) that assigns all flowlines into units that are representative of ecological stream reaches. These "ecological stream reaches" may be defined by: stream origins, stream confluences, lake or reservoir inflows or outflows,...

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...
