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...

These data sets were derived from surveys at the Missouri River and Papillion Creek Water Resource Recovery Facility outfalls on the Missouri River. Each site had three transects, one at the outfall, one 45.7 meters upstream of the outfall and one 45.7 meters downstream of the outfall. Velocity and depth data were collected using an acoustic Doppler current profiler at each transect...

This groundwater flow model used a previously developed three-dimensional groundwater flow model (https://doi.org/10.3133/sir20165153) was used to assess future groundwater availability in the Northern High Plains aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. In this groundwater flow model, a modified version of a previously published soil-water-balance (SWB) model...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Milford Lake and the Republican River, Kansas, during May 2016 through June 2020. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the federal open-data requirements as a way to make scientific products

This U.S. Geological Survey (USGS) data release provides zooplankton data collected from Cheney Reservoir, Kansas, during October 2008 through July 2021. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Cheney Reservoir, Kansas, during June 2001 through September 2020. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS...

This U.S. Geological Survey (USGS) Data Release provides selected discretely measured water-quality data collected from 27 monitoring sites in Johnson County, Kansas, during January 2015 through November 2018. Water-quality samples were analyzed for nutrients, Escherichia coli bacteria, total suspended solids, suspended-sediment concentration, and chlorophyll as part of a study to assess...

This data set is a raster that represents the groundwater-level surface within the Bazile Groundwater Management Area (BGMA) in spring of 2017. This raster was created for use within the Geoscene3D program which combines airborne electromagnetic geophysical data along with supporting information for visualization and geological modeling. A water-level surface was created as input to a...

Cyanobacteria are common in inland water bodies. Many strains are known to produce potent toxins (cyanotoxins) which can impact human and animal health in sufficient concentrations. Lake Elsinore and Canyon Lake are two impaired lakes in California with frequent cyanobacteria blooms that are not monitored for toxin production. These data document the liquid chromatography triple...

Cyanobacteria are primary producers present in many water bodies, certain types of which may produce potent toxins (known as cyanotoxins). They are known to impact human and animal health when exposed through recreational activities, consumption, and inhalation. In an effort to understand the presence of toxin-producing cyanobacteria in California water bodies, cyanobacteria samples were...

Comprehensive list of carcasses detected at Haul Trail in Bayou Sauvage National Wildlife Refuge (Orleans Parish, LA) and relevant findings for specimens subject to postmortem examination at the USGS National Wildlife Health Center (Madison, WI).

This U.S. Geological Survey (USGS) Data Release provides time-lapse color photography collected from three sites at Milford Lake, Kansas, during June through November 2017 and June through November 2018. Photographic images are displayed using a .mp4 common multimedia format. Time-lapse cameras were used to visually capture cyanobacterial accumulations and movement throughout Milford...
