Brackish Groundwater Assessment
All water naturally contains dissolved solids that, if present in sufficient concentration, can make a water resource "brackish", or distastefully salty. The amount of fresh or potable groundwater in storage has declined for many areas in the U.S., leading to concerns about the future availability of water. Using brackish groundwater could supplement or, in some places, replace the use of...
National Brackish Groundwater Assessment: Pilot Saline Studies
Three pilot studies were conducted (2010-2012) to assess saline groundwater resources at regional scales. The goals of the pilot studies were to determine the availability of data for assessing the distribution and character of saline groundwater and test and develop methodologies for assessing the resource.
Integrated Water Availability Assessments (IWAAs)
The USGS Integrated Water Availability Assessments (IWAAs) are a multi-extent, stakeholder driven, near real-time census and prediction of water availability for both human and ecological uses at regional and national extents.
Integrated Water Availability Assessments: Upper Colorado River Basin
Integrated Water Availability Assessments examine water supply, use, and availability. Snow from the Upper Colorado River Basin contributes 92% of the natural streamflow to the entire Colorado River Basin. The UCOL IWAAs will improve our understanding of the water budget, status and trends in water quality and ecological conditions, and ecosystem response to changes in climate and human water use.
National Water Census
The National Water Census will deliver routinely updated water availability information in the United States.
Water Use
Through the National Water Census, USGS will provide national information on withdrawal, conveyance, consumptive use, and return flow by water-use category at spatial and temporal resolutions important for risk-informed water management decisions. Water-use data provide a foundation for water managers to analyze trends over time, plan more strategically, identify, and ultimately quantify...
Focus Area Studies
Focus Area Studies were stakeholder-driven assessments of water availability in river basins with known or potential conflict. They contributed toward ongoing assessments of water availability in large watersheds, provided opportunities to test and improve approaches to water availability assessment, and informed the National Water Census with local information. These studies focused on key water...
Regional Groundwater Availability Studies
Regional groundwater availability studies enable information about groundwater to be integrated and consistent, so that this resource can be analyzed and understood on an aquifer–wide scale. These studies provide decision–makers with a better understanding of the status and trends in the Nation's groundwater availability.
Apalachicola-Chattahoochee-Flint River Basin Focus Area Study
As one of several National Focus Area Studies within the USGS National Water Census (NWC) the USGS completed a 3-year study of water availability and use in the Apalachicola-Chattahoochee-Flint (ACF) River Basin.
Delaware River Basin Focus Area Study
As one of several National Focus Area Studies within the USGS National Water Census (NWC), the USGS completed a 3-year study of water availability and use in the Delaware River Basin.
Apalachicola-Chattahoochee-Flint River Basin Focus Area Study: Drought Impacts on Streams and Groundwater
During 2011 drought conditions in the ACF basin provided an opportunity to document streamflow and groundwater levels under these extreme conditions. Over 350 water levels were measured in wells and streamflow was measured at 212 streams or springs.
Apalachicola-Chattahoochee-Flint River Basin Focus Area Study: Water Use
Water use estimates and water returns for the ACF Basin were estimated and compiled by category and location during 2010. Categories included public supply, self-suppled domestic, self-supplied commercial, industrial, mining, agricultural (crop irrigation, livestock, and aquaculture), and thermoelectric-power generation. Methods for estimating irrigation water use were compared and evaluated...
