Data

This dataset includes water-quality data and saturated hydraulic conductivity based on field measurements of infiltration at two stormwater filters in Coon Rapids, Minnesota. The two filters include: (1) Woodcrest which consists of side-by-side filter beds, one containing an iron-enhanced sand media and the other containing iron-enhanced sand plus biochar, and (2) Epiphany which consists...

The U.S. Geological Survey, in cooperation with the Minnesota Department of Health, conducted a study to determine the occurrence of unregulated contaminants in source and finished drinking waters throughout Minnesota. Minnesota relies on both groundwater and surface water sources for drinking water, which may be vulnerable to influences such as wastewater discharge and/or agricultural...

In support of the U.S. Army Corps of Engineers Long Term Resource Monitoring Mississippi River program, water quality data were collected in 2024 and 2025 in the Upper Mississippi River Basin. Data were collected in 2024 to document spatial heterogeneity in water quality across seasons and hydrologic conditions with a focus on understanding patterns in chlorophyll. Additional data were...

In support of multiple Great Lakes Restoration Initiative (GLRI) projects focusing on Green Bay and upland sources, surface water quality metrics related to primary producers, nutrients, and conductivity were measured using a boat-mounted, continuous sampling platform. These data are used to document changes in water quality as water flows from Lake Winnebago through the lower Fox River...

This data release contains a model archive, ancillary data, and outputs for an application of the Soil-Water-Balance (SWB) model code (version 2, Westenbroek and others, 2018) to simulate water budget components at a 1-kilometer resolution for the state of Minnesota. The SWB model was calibrated to streamflow and actual evapotranspiration observations in 71 watersheds for 2000 - 2022...

We deployed a sampler to characterize water quality from a household well tapping a shallow fractured dolomite aquifer in northeast Wisconsin. The sampler was deployed from January to May 2017, and monitored temperature, nitrate, chloride, specific conductance, and fluorescent dissolved organic matter on a minute time step; water was directed to sequential microbial filters during three...

Under the Great Lakes Restoration Initiative, the U.S. Geological Survey Mercury Research Lab (USGS MRL) conducted a multiyear assessment of mercury across the Laurentian Great Lakes. Biannual sampling was conducted across all five lakes onboard the U.S. Environmental Protection Agency (US EPA) research vessel Lake Guardian (in years 2010–2014, 2018) at pelagic sampling locations...

This data release contains input data and a model archive for a study that used particle image velocimetry to estimate the phosphorus load transported by floating surface material into Green Lake, Wisconsin from May 19 to October 31 of 2023 and 2024. It contains all raw input data and data processing code to reproduce results in the associated primary publication. Inputs to the model...

This data release provides phytoplankton environmental DNA (eDNA) data from 19 sites in 12 different streams within the Milwaukee Metropolitan Sewerage District Planning Area in and around Milwaukee, WI. These streams include the Milwaukee River, the Kinnickinnic River, the Menomonee River, and more. Phytoplankton composition was determined using eDNA sequencing techniques. Data were...

This data release provides tabulated geomorphic data from surveys for nine reaches along the Bad River and its tributaries the Marengo and Potato Rivers, ranging from 2003 to 2024. Included on this page is a tabulated inventory of all the data files (child items) and additional information associated with each reach. Child items are listed by their corresponding reach number. As data was...

This data release provides phytoplankton environmental DNA (eDNA), cyanotoxin biosynthesis gene abundance, phytoplankton microscopy, and cyanotoxin data collected from Ellsworth Rock Gardens in Kabetogama Lake at Voyageurs National Park (USGS site ID: USGS-482947092584401). These samples were collected three times, about every 12 hours, between September 17 and September 18, 2024...

The National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota is the site of a 1979 high-pressure crude oil pipeline rupture. Approximately 1.7 million liters of crude oil spilled onto the glacial outwash aquifer. After remediation and natural attenuation, an estimated 25% of the oil remains in the subsurface today. Groundwater monitoring at the site...
