Falcone, J.A., Baker, N.T., and Price, C.V., 2017, Watershed boundaries for study sites of the U.S. Geological Survey Surface Water Trends project: U.S. Geological Survey data release,


This product contains 1,297 watershed boundaries for water quality study sites of the U.S. Geological Survey (USGS) National Water Quality Program (NWQP) Surface Water Trends project. These include sites where water quality information was collected by both USGS and non-USGS agencies. The data consist of 1,285 boundaries in the conterminous United States, and 12 in Puerto Rico. Twenty-seven percent of boundaries were assembled from other efforts within the USGS which are using the same sites, and 73 percent of boundaries were created new for this project. The data are posted as a single shapefile with separate polygons for each boundary.

The purpose of this dataset is to provide watershed boundaries for the USGS Surface Water Trends project of the National Water Quality Program (NWQP). They are intended as supportive data for study sites described in Oelsner and others (2017). The goal was to acquire already-published or already-verified boundaries from other programs within the USGS, and to have all boundaries agree with, as completely as possible, the boundaries of the Watershed Boundary Dataset (WBD) (U.S. Department of Agriculture, 2013).
