Data

This U.S. Geological Survey (USGS) Data Release provides microcystin, chlorophyll, and cell-count data for assessing the effect of salinity tolerance on cyanobacteria associated with a harmful algal bloom in Lake Okeechobee, Florida. All data are reported as raw measured values and are not rounded to USGS significant figures. Water and algal bloom material were collected from Lake...

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...

The U.S. Geological Survey, in cooperation with the Lewis and Clark, Lower Elkhorn, Lower Loup, Lower Platte North, Lower Niobrara, Middle Niobrara, Upper Elkhorn, and the Upper Loup Natural Resources Districts, designed a study to refine the spatial and temporal discretization of a previously modeled area. This updated study focused on a 30,000-square-mile area of the High Plains...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from John Redmond Reservoir in Coffey County, Kansas, on October 7, 2014, August 13, 2015, and April 25, 2016. All data are reported as raw measured values and are not rounded to USGS significant figures. Continuous water-quality monitors were used to measure water temperature, specific...

The U.S. Geological Survey (USGS), in collaboration with the Platte River Recovery and Implementation Program, collected capacitively coupled (CC) resistivity data and six direct push sediment cores to identify the coarsest alluvial deposits underlying the Morse properties in central Nebraska to supplement the subsurface geologic information, for the purposes of proper siting of...

Deltaic sand deposits at the head of Lewis and Clark Lake, Nebraska-South Dakota were investigated for suitability for use as a proppant feedstock resource in unconventional oil or gas production. The physical characteristics of the deposits are described in four supplemental data sets in varied file formats. First, for the direct-push cores collected at four sandbar complexes in the...

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 June 2016. 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 the...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from Milford Lake, Kansas, on July 27 and August 31, 2015. All data are reported as raw measured values and are not rounded to USGS significant figures. Continuous water-quality monitors were used to measure water temperature, specific conductance, turbidity, pH, chlorophyll, phycocyanin...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Milford Lake, Kansas, during July 27 and August 31, 2015. This data release was produced in compliance with the federal open-data requirements as a way to make scientific products associated with USGS research efforts and publications available to the public. The dataset includes all samples...

This U.S. Geological Survey (USGS) Data Release provides continuously-measured water-quality data collected from two sites on Milford Lake, Kansas, during July 26-27 and August 30-31, 2015. All data are reported as raw measured values and are not rounded to USGS significant figures. Water-quality monitors were used to measure water temperature, specific conductance, turbidity, pH...

This U.S. Geological Survey (USGS) Data Release provides continuously measured water-quality data collected from four Indian Creek sites in Johnson County, Kansas during July 22-25, 2014 and August 21-27, 2015. Water-quality monitors were used to measure water temperature, dissolved oxygen, pH, specific conductance, turbidity, chlorophyll, phycocyanin, and nitrate at fifteen-minute...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from Indian Creek in Johnson County, Kansas, on May 23, 2013, July 23, 2014, July 30, 2015, and August 26, 2015. Continuous water-quality monitors were used to measure water temperature, specific conductance, pH, turbidity, dissolved oxygen, chlorophyll, phycocyanin, nitrate, and fluorescent...
