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. According to the U.S. Geological Survey, an estimated 258 million people nationwide, or 86% of the U.S. population, relied on public water supplies for their household use in 2005 (USGS, 2013). The remaining population obtains their water from different sources, such as a domestic self-supply well. However, the spatial distribution of water supply systems has not been compiled. Mapping where these people are located can be done within...

This dataset is the digital hydrologic unit boundary layer for the 8-digit subwatershed boundaries for the conterminous United States. This dataset is intended to be used with the following two tabular dBase files: https://water.usgs.gov/lookup/getspatial?ds573_tillage_lu92e and https://water.usgs.gov/lookup/getspatial?ds573_tillage_lu01. The two tabular datasets contain the Tillage Practices in the Conterminous United States, 1989-2004---Datasets...
