Suspended-sediment and sand concentrations, streamflow, acoustic data, linear regression models, and loads for the Lower Minnesota River, 2012-2019 Suspended-sediment and sand concentrations, streamflow, acoustic data, linear regression models, and loads for the Lower Minnesota River, 2012-2019
A series of linear regression models were developed and calibrated for two Lower Minnesota River sites. The linear regression models were either calibrated using acoustic or streamflow data to estimate suspended-sediment or sand concentration data. Data were collected during calendar years 2012 through 2019. The estimates of suspended-sediment and concentrations from the linear...
Lake Erie Aquatic Vegetation data Lake Erie Aquatic Vegetation data
Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic...
2018 Emiquon and Spunky Bottoms Preserves, 4-Band Mosaics 2018 Emiquon and Spunky Bottoms Preserves, 4-Band Mosaics
This mosaic was created using high-resolution aerial imagery collected on September 14, 2018 with a Phase One iXU-R 180 aerial camera co-mounted with a Phase One iXU-RS 160 Achromatic camera. The raw image files from the two cameras are combined to create 4-band imagery. The mission was flown at approximately 1,2000 meters above ground level resulting in a ground sample distance of 0.15...
Object-Based Image Analysis Detection of Aquatic Vegetation, Lake Erie, 2018 Object-Based Image Analysis Detection of Aquatic Vegetation, Lake Erie, 2018
The USGS developed the second in a series of informative spatial distribution datasets of submersed aquatic vegetation (SAV) in Lake Erie. The second dataset was developed by object-based image analysis of high-resolution imagery (US waters less than 6 meters deep) collected during peak biomass in 2018 to allow assessments of changes in SAV distribution. Assessing SAV abundance may...
2001 Upper Mississippi River Pool 8 Rake Study Data Set. 2001 Upper Mississippi River Pool 8 Rake Study Data Set.
The Yin et al. 2000 rake method is used by researchers in the Upper Mississippi River Restoration Program to estimate the distribution of submersed aquatic vegetation on the Upper Mississippi River System. Biomass data were collected in 2001 to assess if the Yin et al. 2000 method could be used to estimate biomass based on the rake density ratings. Sediment samples also were collected to...
fishStan fishStan
fishStan is an R package (R Core Team 2020) providing a collection of hierarchical Bayesian models written in the Stan language as called through RStan (Stan Development Team 2020). The package is a USGS software software release. The purpose of the package is to document these models for use in USGS projects and allow easy discrimination. The package assumes the user is familiar with R...
Heuristic MODFLOW models used to evaluate the effects of pumping groundwater from confined aquifers overlain by till confining units Heuristic MODFLOW models used to evaluate the effects of pumping groundwater from confined aquifers overlain by till confining units
This groundwater-flow model archive contains heuristic model simulations evaluating the sustainability of groundwater withdrawals from public-water-supply wells on buried glacial aquifers. A total of 40 steady-state simulations and three transient simulations were run. The steady-state simulations were developed to assess the extent and connections between buried sand aquifers by varying...
Mercury concentrations and isotopic compositions in biota and sediments from the Hannibal Pool of the Ohio River Mercury concentrations and isotopic compositions in biota and sediments from the Hannibal Pool of the Ohio River
The Hannibal Pool of the Ohio River is heavily industrialized and receives direct effluent discharges from coal power plants, chlor-alkali plants, and sewage treatment facilities. Mercury (Hg) is a contaminant of concern due to the risk of bioaccumulation at wildlife refuges also located within this region. Mercury concentrations and isotopes compositions were measured to assess the...

Bottom sediment chemical data at rivermouths and harbors along western Lake Michigan, USA, 2016 Bottom sediment chemical data at rivermouths and harbors along western Lake Michigan, USA, 2016
Streambed sediment samples were collected in October 2016 from streams tributary to Wisconsin?s western Lake Michigan shoreline. Streams included two Areas of Concern (AOCs), two non-AOC comparisons, and two additional non-AOC study areas. Within the Milwaukee Estuary AOC, samples were collected from the Milwaukee River (three subsites), the Menomonee River (two subsites), the...
Arsenic, manganese, and pH groundwater quality data, selected well construction characteristics, and aquifer assignments for wells in the conterminous U.S. Arsenic, manganese, and pH groundwater quality data, selected well construction characteristics, and aquifer assignments for wells in the conterminous U.S.
This data release contains groundwater-quality data for three parameters of interest (arsenic, manganese, and pH) and well information for sample sites for aquifers in the conterminous U.S. Water-quality data and well information were derived from a dataset compiled from three sources: the U.S. Geological Survey (USGS) National Water Information System (NWIS), the U.S. Environmental...
