Data and Tools

Continuous and discrete surface-water, groundwater, and water-quality data are collected to provide long-term hydrologic records critical to investigating hydrology, modeling climate-change, evaluating natural and anthropogenic changes in the hydrologic regime, and providing information on water availability to water managers.

Water-level contours along the Lower Platte and Lower Elkhorn Rivers, Nebraska, 2016-2017

This data set contains two sets of water-level contours that represent interpreted water-levels for an area between the Platte and Elkhorn Rivers upstream of their confluence. The contours are informed by surface-water and groundwater-level data collected during a synoptic water-level survey completed during a low-groundwater demand period in fall of 2016 and a synoptic water-level survey...

Water-level and digital data for the Elkhorn and Loup River Basins groundwater flow model, Phase Three

This updated study focused on a 30,000-square-mile area of the High Plains aquifer and constructed regional groundwater-flow models to evaluate the effects of groundwater withdrawal on stream base flow in the Elkhorn and Loup River Basins, Nebraska.

Monitoring Data for Willow Creek Lake, Nebraska, 2012-14

Monitoring data were collected from the Willow Creek drainage basin and Willow Creek Lake with a focus on 2012-14. Included are datasets of meteorology; lake measurements of water levels, sediment nutrients, and physical, chemical, and biological data; streamflow and stream chemistry; and calculated nutrient loads to the lake.

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Lake Level

Daily measurements of Willow Creek Lake water storage were provided by the Nebraska Department of Natural Resources for 2012–14. These water levels were used in conjunction with a table (provided by the Lower Elkhorn Natural Resources District) relating lake storage volume to surface area. From these, daily estimates of surface area were derived for the lake.

Niobrara River suspended-sediment and bed-sediment data collected during hydroelectric dam flush near Spencer, Nebr., October through November, 2014

In the fall of 2014 (October-November) the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers collected sediment samples (suspended and bed material) at several sites on the Niobrara River in Nebraska near the Spencer Dam prior to, during, and immediately after a sediment-flushing event. Suspended-sediment samples were analyzed for sediment concentration and p

Depth grids of the flood-inundation maps for the Salamonie River at Portland, Indiana

Digital flood-inundation maps for a 6.5-mile reach of the Salamonie River at Portland, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at https://water.usgs.gov/...

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Profiler

The data set contains vertical profiles of physical (water temperature, specific conductance, pH, dissolved oxygen, and turbidity) and biological measurements (chlorophyll-a and phycocyanin) that were measured hourly and then summarized on a daily basis within Willow Creek Lake during the non-winter seasons.

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Sediment Nutrients

The retention or release of nutrients into the water column from sediment, also known as internal loading, is another source of nutrients to the lake water column. Sediment cores collected from Willow Creek Lake in September 2013 and June 2014 were incubated for 7 days to assess potential for sediment to produce or consume water column phosphorus under aerobic (oxic) and anaerobic (ano

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Meteorology

A meteorological station was deployed on the dam to measure hourly relative humidity, wind speed and direction, and photosynthetically active radiation between August 3, 2012 and October 30, 2014, with air temperature and solar radiation added on April 30, 2013. Additional meteorological data were obtained from the National Climatic Data Center (2015): Precipitation data were obtained from...
