Groundwater-Quality Monitoring near Ashland, Nebraska
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...
Bathymetric and Topographic Survey of the Platte River and associated chutes near the Nebraska Army National Guard Camp Ashland Training Site, 2019-2020
These data are the survey results from a five-mile section of the Platte River at, and upstream of the Nebraska Army National Guard Camp Ashland Training Site including the side channel chutes on the east bank. All survey data were collected along planned transect lines that were spaced 492.125 US survey feet apart beginning near the mouth of the Elkhorn River and ending near the U.S. Highway 6 br
Selected anthropogenic contaminants in groundwater, Papio-Missouri River Natural Resources District, eastern Nebraska, 1992–2020
A study in cooperation with the Papio-Missouri River Natural Resources District was completed in 2019 to determine the concentration of contaminants of emerging concern (CEC) in groundwater in the Papio-Missouri River Natural Resources District, eastern Nebraska. Each well was sampled twice (in June and October or November) in 2019, totaling 34 samples. Samples were analyzed for 132 CECs, which in

Hydrographic surveys at seven chutes and three backwaters on the Missouri River in Nebraska, Iowa, and Missouri, 2011-13
The U.S. Geological Survey cooperated with the U.S. Army Corps of Engineers (USACE), Omaha District, to complete hydrographic surveys of seven chutes and three backwaters on the Missouri River yearly during 2011–13. These chutes and backwaters were constructed by the USACE to increase the amount of available shallow water habitat (SWH) to support threatened and endangered species, as required by t
