Data

This data release includes mercury concentrations and mercury stable isotope measurements measured in sediments and biological tissues collected from the Saint Louis River located in Minnesota. Sediments and biota were collected by the U.S. Geological Survey, U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, and federal contractors (Battelle) from 2017-2021. Collection...

From September 2019 to October 2020 a stream sediment budget and sediment fingerprinting integrated study was conducted to quantify upland and stream corridor sources of suspended sediment and sediment-bound phosphorus using the Sediment Source Assessment Tool (SedSAT) methods with a suite of trace elements. Upland source samples were collected at 45 randomly selected sites in the...

This date release was produced as part of the Milwaukee Area Watercourse Corridor Study in partnership with the Milwaukee Metropolitan Sewerage District (MMSD) to monitor and assess stream water quality within studies of aquatic communities, geomorphology and habitat, water and sediment, and streamflow. This dataset contains two vector datasets of stream geomorphic characteristics, pre...

This model archive makes available the U.S. Geological Survey Soil-Water-Balance (SWB) model created in support of a groundwater flow model of the former Badger Army Ammunition Plant in Sauk County, Wisconsin. The SWB model provides initial estimates of potential recharge to the groundwater system in the study area, which are used in a calibrated 3-dimensional MODFLOW (modular finite...

In the Great Lakes basin, there are numerous organizations undertaking scientific monitoring and research efforts with the goal of identifying threats and evaluating management strategies that will protect and restore the Great Lakes ecosystem. Coordination among all these stakeholders is a challenge, and having a centralized location where researchers and managers can identify relevant...

This model archive summary (MAS) documents the suspended-sediment concentration (SSC) model developed to compute 15-minute SSC from turbidity readings. This is the first model developed for the Blue Earth River at Highway 169 at Mankato, Minnesota (Station ID 05321195).

This model archive makes available a calibrated, transient MODFLODW-NWT model and a MODPATH7 particle-tracking model used to simulate the groundwater flow system at the former Badger Army Ammunition Plant, in Sauk County, Wisconsin, during 1984–2020. The development of the MODFLODW-NWT and MODPATH7 models are described in the associated U.S. Geological Survey Scientific Investigations...

This data release contains water level data and analytical results from slug tests performed at 12 wells at Badger Army Ammunition Plant (BAAP), Sauk County, Wisconsin. Water-level data, representing the displacement and recovery of groundwater levels with time in wells during slug tests, are provided in comma delimited files. Analytical results are provided in AQUTESOLV files (*.aqt...

Corrected and aggregated temperature data from the subsurface of three permeable pavement types [permeable interlocking concrete pavers (PICP), pervious concrete (PC), and porous asphalt (PA)] collected in Madison, Wisconsin between November 1 and April 30 (cold-weather periods), 2014-2021 are in this data release. Temperature data was corrected through removal of intermittent erroneous...

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...

The Kalamazoo River Area of Concern (AOC) in Michigan has multiple dams in various stages of removal. Following dam removal, river restoration activities will occur in impacted reaches. Hydrogeomorphic data from relatively undisturbed and hydraulically stable river reaches are commonly used to inform the design parameters of river restoration projects. Reference reaches should be...

Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and...
