Water Availability and Water Use
Water Availability and Water Use
How much water is available and how water resources are used are critical questions for managers of Nebraska's water resources. USGS scientists use models to simulate how water use may affect water resources, study the interaction between groundwater and surface water, and monitor water levels throughout the state.

Assessing drought resilience of the South Loup River using age tracer, streamflow, and continuous water-quality data
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.
Groundwater/surface-water interaction near the confluence of the Elkhorn and Lower Platte Rivers
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...
High Plains Groundwater Availability Study
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...
High Plains Water-Level Monitoring Study
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...
Groundwater Quality and Age of Secondary Bedrock Aquifers, Eastern Nebraska
In eastern Nebraska, secondary aquifer systems are increasingly being considered to supplement growing municipal, domestic, and agricultural water demands. Within the Eastern Nebraska Water Resources Assessment (ENWRA) area, airborne geophysical surveys have mapped the thickness and extent of these aquifers over much of eastern Nebraska; however little is known about the age and quality of water...
Water Movement Through the Unsaturated Zone of the High Plains Aquifer in the Central Platte Natural Resources District, Nebraska
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.
