Data Releases

This U.S. Geological Survey (USGS) data release includes Escherichia coli (E. coli) data and also continuous hydrologic and physical parameters at USGS streamgage sites on the Little Blue River and its tributaries in Independence, MO, during the 2010-2016 recreation seasons. The U.S. Geological Survey, in coordination with the City of Independence, collected the data for use in regression models t

To document current marsh conditions, imagery was acquired at 350 feet using unmanned aerial systems (UAS) for 6 separate study locations. Three Sites are healthy marsh and three sites are degraded marshes. For each study site, ground control markers were established and surveyed in using Real Time Kinematic (RTK) survey equipment. The imagery collected will be processed to produce a mosaics for e

This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed), dissolved

The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS). Aerial images of Pools 3-13 Upper Mississippi River System and Pools, Alton-Marseilles, Illinois River were collected in color infrared (CIR) in August of 2010 at 8/pixel and 16/pixel respectively using a mapping-grade Appl

This U.S. Geological Survey Data Release provides data collected from Nolin Lake Kentucky, during 2016 to 2017. Two types of data are reported: zooplankton and phytoplankton data are raw calculated values not rounded to USGS significant figures and continuous water-quality data collected with a multi-parameter sonde. The zooplankton, phytoplankton, and water-quality data describe a swarm of the in

These data were used for an analysis as part of a long-term project monitoring the biological communities, habitat, and water quality of the Fountain Creek Basin. Biology, habitat, and water quality data have been collected at 10 sites starting in 2003. These data include annual samples of aquatic invertebrate communities, fish communities, water quality, and quantitative riverine habitat collecte

Natural river channels continually evolve and change shape over time. As a result, channel evolution or migration can cause problems for bridge structures that are fixed in the flood plain. A once-stable bridge structure that was uninfluenced by a rivers shape could be encroached upon by a migrating river channel. The potential effect of the actively meandering Wabash River on the Interstate 64 (I

The U.S. Geological Survey, in cooperation with the Minnesota Pollution Control Agency, conducted a study to determine the occurrence of micropollutants in: (1) shallow groundwater near large subsurface treatment systems and rapid infiltration basins and (2) shallow groundwater and soil from an agricultural field that land applies domestic wastewater. Water samples were analyzed with enzyme linked

This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also

Between 2005 and 2010, 61 adult female elk were trapped using a baited corral trap on Fossil Butte National Monument during winter. An additional 12 female elk were darted from a helicopter during the winter of 2007 near Cokeville, WY, located approximately 20 km northwest of the Monument. We affixed all elk with GPS collars programmed to collect location data every 5 hours. In total we collected
