This product was updated. The newest version can be found here: https://www.sciencebase.gov/catalog/item/546a1950e4b04d4b7dbde8f1. Using a combination of tabular and spatial data queries, we identified 121,207 flowlines in the hydrological framework of the 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_ecoreach.csv) that assigns all flowlines into units that are representative of ecological stream reaches. Using similar techniques as described in...

Using a combination of tabular and spatial data queries, we identified 124,233 flowlines in the NHDPlusV2 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 NHDplusV2 dataset. To aid in managing for this characteristic of the NHDPlus, this EcoReach table (nhdplusv2_ecoreach.csv) assigns all flowlines into units that are representative of ecological stream reaches. Using techniques described in this metadata a similar table was developed for the NHDPlusV1...

This geodatabase contains landscape factors representing human disturbances summarized to local and network catchments of river reaches throughout the conterminous U.S. They include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. In this data set, these variables are linked to the catchments...

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...
