Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. A digital hydrologic network was developed to support SPAtially Referenced Regression on Watershed attributes (SPARROW) models within selected regions of the United States. These regions correspond with the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program Major River Basin (MRB) study units 2, 3, 4, 5, and 7 (Preston and others, 2009). MRB2, covers the South Atlantic-Gulf and Tennessee River basins. MRB3, covers the Great Lakes, [...]

Purpose

The purpose of this dataset was to provide a framework to spatially reference and summarize explanatory information supporting nutrient SPARROW models in selected regions of the conterminous United States. The digital hydrologic network also is used to map spatial distributions of nutrient predictions provided by SPARROW. In addition, the topology of this hydrologically connected network allows for the simulation of water movement, providing the ability to accumulate flow and route constituents throughout the river network. Although developed and modified specifically for SPARROW modeling applications, the dataset is suitable for other large-scale watershed studies and applications.
