thumbnail Hydrologic Datasets to Aid Water Management in the Upper Klamath Basin, Oregon –USGS, in cooperation the Klamath Tribes and in collaboration with Klamath Basin Rangeland Trust, Klamath Watershed Partnership, Sustainable Northwest, The Nature Conservancy, Upper Klamath Water Users Association, and U.S. Fish and Wildlife Service, has developed hydrologic datasets for the upper Klamath Basin of south-central Oregon that can help water managers identify and prioritize water uses that could be voluntarily set aside and reallocated to yield an additional 30,000 acre feet of water to Upper Klamath Lake. The datasets can be used by water managers to display the geographical distribution of evapotranspiration, sub-irrigation, water rights, streamflow statistics, and irrigation return flow in the upper basin—crucial information for understanding potential impacts of any changes in allocation. Used together, the datasets can help managers determine the relative benefits of retiring water uses and/or redirecting specific water rights to address water-resource issues specified in the Klamath Basin Restoration Agreement.

thumbnail Online Screening Tool for New Water Withdrawals in Michigan –The State of Michigan ratified the Great Lakes-St. Lawrence River Basin Water Resources Compact on July 9, 2008, and under the Compact, agreed to develop implementation legislation to prevent adverse resource impacts of water withdrawals on the ecosystems and watersheds within the Basin. Through cooperative science projects, USGS, in cooperation with the State of Michigan and Michigan State University, provides science to support to the state in the development of an innovative water-withdrawal assessment process and on-line screening tool for new or increased water withdrawals (On-line screening tool). This process combines ungaged-flow estimation, a statewide ecological flow classification of streams, estimation of streamflow depletion by wells, and ecological-response curves describing the potential impact of water withdrawals on characteristic fish populations within a legislative and management framework.


thumbnail Projected Water Use and Groundwater Scenarios through 2060 in Parts of Nevada and California –USGS, in cooperation with the Carson Water Subconservancy District, assessed potential effects of changes in water use with a numerical groundwater flow model of Carson Valley, Douglas County, Nevada, and Alpine County, California. Rapid growth and development within Carson Valley in Douglas County, Nevada, and Alpine County, California has caused concern over the continued availability of groundwater, and whether the increased municipal demand could either impact the availability of water or result in decreased flow in the Carson River. The groundwater-flow model was used in five 55-year predictive simulations to evaluate the long-term effects of different water-use scenarios on water-budget components, groundwater levels, and streamflow in the Carson River. The predictive simulations represented water years 2006 through 2060. (Full report)


thumbnail New Louisiana Water Use Report Available –New statistics on the use of water in Louisiana are presented in a recent report by the USGS, done in cooperation with the Louisiana Department of Transportation and Development. In 2010, approximately 8,500 million gallons of water per day (Mgal/d) were withdrawn from ground and surface-water sources in Louisiana. The full report, as well as previous reports and water-use data done on a five-year basis since 1960, is available online. (Technical announcement)


thumbnail Groundwater Storage and Recharge Ponds Successful in Stockton, California –USGS, in cooperation with the City of Stockton, assessed the feasibility of recharging underlying aquifers by infiltrating water through recharge ponds into the aquifer system. Stockton relies on groundwater for about 20 percent of its public supply, but water withdrawals have exceeded the amount of water naturally entering the aquifer system, resulting in declining groundwater levels. Using surface water and stormflow to recharge groundwater by infiltration through ponds can have beneficial effects on water quality. These benefits, including the removal of organic carbon and the decrease of microbiological contamination, allow for the recharge of aquifers using water with potentially impaired water quality, enabling groundwater managers to consider previously unusable sources for water supply.

thumbnail Irrigation use data for the Middle and Lower Chattahoochee and Flint River Basins, Georgia –USGS, in cooperation with the Georgia Soil and Water Conservation Commission (Commission), released a report on the Georgia Agricultural Water Conservation and Metering Program. Since receiving jurisdiction from the State Legislature in June 2003 to implement the metering program, the Commission by year-end 2010 installed more than 10,000 annually read water meters and nearly 200 daily reporting, satellite-transmitted, telemetry sites on irrigation systems located primarily in southern Georgia. Geostatistical models facilitated estimation of irrigation water use for unmetered systems and demonstrated usefulness in redesigning the telemetry network.


thumbnail Consumptive water use in irrigated agricultural settings in Central Colorado –Water management and determination of consumptive water use in irrigated agricultural settings depend on understanding factors such as surface-water diversions, groundwater withdrawals, evapotranspiration, tail-water runoff, and deep-percolation return flow of water beneath irrigated fields. To improve understanding of deep-percolation return flow beneath irrigated fields, USGS, in cooperation with the Central Colorado Water Conservancy District, conducted a study to estimate deep-percolation return flow at two irrigated sites in the Central Colorado Water Conservancy District during the 2008 and 2009 irrigation seasons.


thumbnail Water-use conservation scenarios in the Mississippi Delta in northwestern Mississippi –USGS, in cooperation with the Yazoo Mississippi Delta Joint Water Management District, developed conservation scenarios for the alluvial aquifer underlying the Delta region in northwestern Mississippi to assess where the implementation of water-conservation efforts would have the greatest effect on future water availability. The Mississippi River alluvial plain in northwestern Mississippi (referred to as the Delta), once a floodplain to the Mississippi River covered with hardwoods and marshland, is now a highly productive agricultural region of large economic importance to Mississippi. Water for irrigation is supplied primarily by the Mississippi River Valley alluvial aquifer, and although the alluvial aquifer has a large reserve, there is evidence that the current rate of water use from the alluvial aquifer is not sustainable.

thumbnail Water use in the Apalachicola- Chattahoochee-Flint River Basins, Alabama, Georgia, and Florida –USGS, in cooperation with the Florida Department of Environmental Protection, summarized water withdrawals, wastewater discharge, and water consumption in the 20,500 square mile basins. Total withdrawals were tracked for 35 years, from 1970 through 2005. (USGS report)


thumbnail Regional and local withdrawals in a fractured-bedrock groundwater system in Northern Wake County, North Carolina –USGS, in cooperation with the Wake County Department of Environmental Services, released a study on the effects of dewatering a fractured-bedrock aquifer on privately owned wells and monitoring wells in a localized area of east-central North Carolina, which were intermittently dry. Although the study itself was localized in nature, the resulting water-resources data and information produced from the study will help enable resource managers to make sound water-supply and water-use decisions in similar crystalline-rock aquifer setting in parts of the Piedmont and Blue Ridge Physiographic Provinces.


thumbnail Statewide estimates on withdrawals and return flows in Vermont and New Hampshire –USGS, in cooperation with New Hampshire Department of Environmental Services and the Vermont Geological Survey, projected 2020 water use for each state. Data, available online, were collected and evaluated at the census-block level and have been aggregated by county, town (MCD), and 12-digit hydrologic unit (watershed). 


thumbnail Allocated and projected effects of groundwater withdrawals in Gloucester and Northeastern Salem Counties, New Jersey – USGS, in cooperation with the New Jersey Department of Environmental Protection, released a report that demonstrates simulated effects of allocated and projected (2025) withdrawals from the Potomac-Raritan-Magothy Aquifer system, a principal source for water supplies in Gloucester and Northeastern Salem Counties, New Jersey. Groundwater levels have declined in response to pumping. With increased population growth and development expected in Gloucester County and parts of Salem County over the next 2 decades (2005-2025), withdrawals from these aquifers also are expected to increase. Increased withdrawals also have threatened saline intrusion and the potability of groundwater supplies derived from the Potomac-Raritan-Magothy aquifer system in the study area. Particle tracking was used to define groundwater flow paths, and a budget analysis of the withdrawal zones was conducted to assess the movement of saline water and the likelihood of continued saltwater intrusion.
