Warming may create substantial water supply shortages in the Colorado River basin Warming may create substantial water supply shortages in the Colorado River basin
The high demand for water, the recent multiyear drought (1999-2007), and projections of global warming have raised questions about the long-term sustainability of water supply in the southwestern United States. In this study, the potential effects of specific levels of atmospheric warming on water-year streamflow in the Colorado River basin are evaluated using a water-balance model, and...

Pesticides in the Nation's Streams and Ground Water, 1992–2001 Pesticides in the Nation's Streams and Ground Water, 1992–2001
This report is one of a series of publications, The Quality of Our Nation's Waters, that describe major findings of the NAWQA Program on water-quality issues of regional and national concern. This report presents evaluations of pesticides in streams and ground water based on findings for the first decadal cycle of NAWQA. 'Pesticides in the Nation's Streams and Ground Water, 1992-2001'...

Development and application of a regression equation for estimating the occurrence of atrazine in shallow ground water beneath agricultural areas of the United States Development and application of a regression equation for estimating the occurrence of atrazine in shallow ground water beneath agricultural areas of the United States
Results from 52 ground-water studies throughout the United States were used to examine relations between the occurrence of atrazine in shallow ground water in agricultural settings and explanatory variables that describe the natural setting, agricultural-management practices, and the type and amount of development in each area. The explanatory variables that were found to be correlated...

USGS Streamgages Linked to the Medium Resolution NHD USGS Streamgages Linked to the Medium Resolution NHD
The locations of approximately 23,000 current and historical U.S. Geological Survey (USGS) streamgages in the United States and Puerto Rico (with the exception of Alaska) have been snapped to the medium resolution National Hydrography Dataset (NHD). The NHD contains geospatial information about mapped surface-water features, such as streams, lakes, and reservoirs, etc., creating a...
