Groundwater

The water supply for the city of Wichita, south-central Kansas, currently comes from the Equus Beds aquifer and Cheney Reservoir. Because these sources are not expected to meet projected city water needs into the 21st century (Warren and others, 1995), artificial recharge of the Equus Beds aquifer was investigated as one alternative to meet future water-supply demands. An additional potential...

The Prairie Band Potawatomi Nation (PBPN) in Jackson County, Kansas lies within the Big Soldier and Little Soldier Creek basins. The PBPN needs surface and groundwater quality and quantity data for water management purposes and for developing and implementing a water quality program to protect the water of the reservation for the benefit of current and future generations. In January 2020, The U.S...

Streams in the Loup River basin have a close hydrologic connection between groundwater and surface water. Groundwater springs are important hydrologic features that sustain the flow of the South Loup River. This study assesses the ability of these springs to maintain consistent flow of the South Loup River over periods of prolonged drought.

Nitrate, age tracer, and continuous groundwater-level data within the BGMA were interpreted in conjunction with AEM data as a case demonstration of the Nebraska Geocloud. The Nebraska Geocloud was initiated to protect taxpayer investments in AEM data collection and realize maximum benefit of these data by creating a publicly available, online digital database for long-term data storage. The Lower...

In 1991, Congress established the National Water-Quality Assessment (NAWQA) to address where, when, why, and how the Nation's water quality has changed, or is likely to change in the future, in response to human activities and natural factors. Since then, NAWQA has been a leading source of scientific data and knowledge used by national, regional, state, and local agencies to develop science-based...

Recent droughts in Nebraska (2000–06; 2012–13) have amplified concerns about the long-term sustainability of groundwater and surface-water resources as well as concerns about the effect of groundwater irrigation on streamflow and water supplies needed to meet wildlife, recreational, and municipal needs. The Lower Platte River Basin-wide Management Plan is currently being developed jointly by the...

Water availability is a function of many factors, including the quantity and quality of water and the laws, regulations, economics, and environmental factors that control its use. The focus of the High Plains Groundwater Availability Study is on improving fundamental knowledge of the water balance of the basin, including the flows, storage, and water use by humans and the environment. An improved...

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. In response to a directive from Congress, the U.S. Geological Survey (USGS), in cooperation with local, state, and federal entities, has collected water-level data from wells screened in the High Plains...

In the Elkhorn River and Loup River Basins, Natural Resources Districts (Upper Elkhorn, Lower Elkhorn, Upper Loup, Lower Loup, Middle Niobrara, Lower Niobrara, Lewis and Clark, and Lower Platte North) are collecting data and developing tools to assist with water resource planning. Critical planning issues in the Elkhorn River and Loup River basins are focused on the availability of the groundwater...

The USGS Nebraska Water Science Center has been collecting groundwater quality samples in cooperation with the Papio-Missouri River Natural Resources District (NRD) since 1992 in support of the NRD's groundwater management plan. The basic geochemistry and age of the groundwater was established. Well waters are sampled yearly throughout the NRD to monitor the resource and assess concentrations of...

Eight unsaturated-zone research sites were installed in the Central Platte Natural Resources District as part of the High Plains Unsaturated-Zone Research Network. These 8 sites were installed to determine recharge and chemical transport rates in the unsaturated zone beneath important land-use settings and climate gradients across the Central Platte Natural Resources District.

Since 1991, the USGS Nebraska Water Science Center has collected water samples from six monitoring wells in the Platte River alluvial aquifer near Ashland. Analytes include major and trace metals, nutrients, dissolved organic carbon, pesticides and their degradates, and arsenic species. The samples are analyzed by the USGS National Water Quality Laboratory. The USGS also collects additional...
