Digital flood-inundation map libraries for two reaches that comprise 14.8 miles of the Little and Big Papillion Creeks in Omaha, Nebraska were created by the U.S. Geological Survey (USGS) in cooperation with the Papio-Missouri River Natural Resource District. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov...

This dataset describes irrigation water use in Kansas in 2016. Volumes of water used, irrigated area, and irrigation application depths are provided for three sets of subareas: (1) Irrigation water use analysis regions that include Groundwater Management Districts (GMDs) with the areas outside of GMDs divided into eastern, central, and western Kansas; (2) Regional Planning Areas (RPAs)...

Coastal communities are uniquely vulnerable to sea-level rise and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in subsequent years. The U.S. Geological Survey has developed the Sediment...

This U.S. Geological Survey (USGS) Data Release includes phytoplankton data collected from four reservoirs in Kansas, during August 2020 through August 2022. All data are reported as raw calculated values and are not rounded to USGS significant figures. The dataset includes all routine and quality assurance/quality control samples collected at twenty-five locations within Marion...

The EPA National Coastal Condition Assessment (NCCA) is a nation-wide survey of coastal and estuarine water quality. During the 2015 EPA NCCA, samples were collected for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by liquid chromatography triple quadrupole mass...

Note: this data release has been superseded by version 3.0, available here: https://doi.org/10.5066/P1BCA8QV. The National Water Quality Network (NWQN) for Rivers and Streams includes 105 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program. This data release provides streamflow, nutrient, and sediment data collected and...

The U.S. Environmental Protection Agency (EPA) National Coastal Condition Assessment (NCCA) is a nationwide survey of coastal and estuarine water quality. During the 2015 EPA NCCA, samples were collected at 732 sites for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by...

This U.S. Geological Survey (USGS) Data Release provides derivative statistics of water used by Kansas public-supply systems in 2016. Gallons per capita per day (gpcd) was calculated using self-reported information in the “Part B: Monthly Water Use Summary” and “Part C: Population, Service Connections, and Water Rates” sections of the Kansas Department of Agriculture, Division of Water...

The High Plains aquifer underlies 111.8 million acres (about 175,000 square miles) in parts of eight States: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Water-level declines began in parts of the High Plains aquifer soon after the beginning of substantial irrigation with groundwater in the aquifer area (about 1950). This data release contains the...

The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand by delivering routine assessments of water supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface...

The Mississippi Alluvial Plain (MAP) is one of the most important agricultural regions in the United States and underlies about 32,000 square miles of Missouri, Kentucky, Tennessee, Mississippi, Louisiana, and Arkansas. The MAP region supports a multibillion-dollar agricultural industry. The MAP is part of the Mississippi Embayment with several water-bearing units that make up the...

The Western Interior Plains aquifer system is located in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming and covers an area of more than 220,800 square miles. The thickness of the aquifer system ranges from 500 feet in eastern Colorado (HA 730-D) to as much as 10,000 feet in western Oklahoma (PP_1414B). This aquifer system...
