The upper Colorado River system is the habitat of several endangered fish: Kendall Warm Springs dace, Colorado squawfish, humpback chub, and bonytail chub. The single most important factor contributing to the decline of these species has been the construction and operation of dams and reservoirs, which have effected flow, temperature, chemistry, biota, and migration routes. Water depletion amounting to about 25% of the total has also had similar effects, particularly by eliminating the backwater nursery areas. A predicted decrease in agricultural use and increase in energy development use would decrease the amount of used irrigation water percolating back into the groundwater and streams. In addition, water allocated...

The water resources in Tennessee are likely to be stressed in the future by factors such as population increase, urban and suburban development, climate change, and other competing demands. Water-resource managers and policy makers will need accurate water-use data for regional water-supply planning including infrastructure investment, conservation, and cost-recovery strategies. Quantifying public-supply and self-supplied industrial water use and relating the use to effects on -water resources and natural hydrologic systems; is important for the public and policy makers. This dataset includes public-supply water-use and self-supplied industrial water-use information for the State of Tennessee in 2010. Public supply...
Groundwater is an often overlooked freshwater resource compared to surface water, but groundwater is used widely across the United States, especially during periods of drought. If groundwater models can successfully simulate past conditions, they may be used to evaluate potential future pumping scenarios or climate conditions, thus providing a valuable planning tool for water-resource managers. Quantifying the groundwater-use component for a groundwater model is a vital but often challenging endeavor. This dataset includes groundwater withdrawal rates modeled for the Ozark Plateaus aquifer system (Ozark system) from 1900 to 2010 by groundwater model cell (2.6 square kilometers) for five water-use divisions: agriculture...
The aridland shrub species, Artemisia tridentata (big sagebrush) and Chrysothamnus nauseosus (rubber rabbitbrush), are distributed widely in the Intermountain region of western North America. Earlier research indicated that A. tridentata can utilize upper soil water from transient summer rain events while C. nauseosus apparently cannot, although both species have similar rooting depths. Thus, we hypothesized that C. nauseosus relies more on deep water than A. tridentata, while A. tridentata can take advantage of soil moisture in upper soil layers. We examined this hypothesis by growing A. tridentata and C. nauseosus in two-layer pots in which soil water content in the upper and lower layers was controlled independently....

Values represent groundwater withdrawals from the Floridan aquifer system for 2000 in the southeastern United States. Withdrawals were computed by multiplying the gross groundwater withdrawals for each county by a coefficient representing the proportion of total groundwater withdrawals coming from each aquifer. Coefficients for each county and water-use category were back-calculated from data published in Marella and Berndt, 2005, Water withdrawals and trends from the Floridan aquifer system in the southeastern United States, 1950–2000: U.S. Geological Survey Circular 1278, 20 p. and also from unpublished data from the U.S. Geological Survey South Atlantic Water Science Center (Georgia District).
ABSTRACT: In many of the limited water resource areas of the western United States most water supplies have been put to beneficial uses. Energy, a fast expanding high-priority water use, is making challenging demands for these limited supplies. Can water supplies be stretched, supplemented, or redirected so that present uses can be maintained and energy water needs satisfied? The Bureau of Reclamation is investigating innovative methods of water management, reregulation, and use to meet these demands. Related programs under study include potentials for: development of additional hydroelectric power, installation of low-head turbines in western water courses, utilization of pumped storage and underground storage,...

This dataset presents offstream water use estimates from 2010 which are aggregated to the 12-digit (subwatershed) hydrologic unit level for the Delaware River Basin. The data support USGS Scientific Investigations Report 2015-5142.
Climate change policy involving a price on carbon would change the mix of power plants and the amount of water they withdraw and consume to generate electricity. We analyze what these changes could entail for electricity generation in the United States under four climate policy scenarios that involve different costs for emitting CO2 and different technology options for reducing emissions out to the year 2030. The potential impacts of the scenarios on the U.S. electric system are modeled using a modified version of the U.S. National Energy Modeling System and water-use factors for thermoelectric power plants derived from electric utility data compiled by the U.S. Energy Information Administration. Under all the climate-policy...

The dataset accompanies Figures 2–4 of Matchett and Fleskes (2018) and therein the subject data are referenced as "Table A1". Data summarize peak abundance (km2) of Central Valley waterbird habitats (i.e., wetland and flooded cropland types) that are available between August and April (of the following year) for each of 17 projected scenarios by planning basin, scenario, and habitat. Area of each habitat for each scenario-basin combination is provided for the month when the most area of the respective habitat is typically flooded and available for waterbird use (i.e., January for all wetlands and winter-flooded rice and corn, and September for other winter-flooded crops in Tulare Basin). The dataset also includes...
Concentrations of atmospheric CO2 and other radiatively active trace gases have risen since the Industrial Revolution. Such atmospheric modifications can alter the global climate and hydrologic cycle, in turn affecting water resources. The clear physical and biological sensitivities of water resources to climate, the indication that climate change may be occurring, and the substantial social and economic dependencies on water resources have instigated considerable research activity in the area of potential water resource impacts. We discuss how the literature on climate change and water resources responds to three basic research needs: (1) a need for water managers to clearly describe the climatic and hydrologic...

This product is a series of six national 1-kilometer (km) raster datasets, for five year intervals between 1985 and 2010, representing USGS Water Use "Total Fresh Water Withdrawals", allocated to areas of land use representing anthropogenic use. Pixels representing anthropogenic uses (urban, agriculture, and mining land uses) are derived from the NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product (Falcone, 2015), a series of decadal national raster datasets for the period 1974-2012. The raster datasets created here are intended as a source of information for estimating water use for watersheds, at the scale of HUC12 watersheds and coarser. Units are millions of gallons per day (mgd) per square km.

This product consists of 29 datasets of tabular data and associated metadata for watershed characteristics of 1,530 study sites of the Surface Water Trends (SWT) project of the U.S. Geological Survey’s (USGS) National Water Quality Program (NWQP). The project is conducting national studies of trends in water quality of streams and rivers for periods ranging from 10 to 40 years, between 1972 and 2012. The data here include both static and time-series characteristics. Static data include primarily physical characteristics which have changed little over this period, such as geology, soils, and topography. Time-series data represent characteristics which may or may not have changed over time, such as land use, agricultural...

The baseline map of the Butte Basin, the representative basin from the Central Valley, was generated first by delineating the extent of the landscape to be modeled, in agreement with the basin boundaries identified by the Central Valley Joint Venture.The Butte Basin (CV) encompasses a region approximately 44km x 64 km, and the map used contains 10,698 individual habitat patches and 179,964 acres of possible foreageable area. Patch habitat types were identified by a combination of USDA CropScape data (to identify agricultural habitat patches including rice and corn) and other local mapping data made available through collaboration with USGS. Habitat flood schedules were generated using the Water Evaluation and Planning...
