The Sheboygan River Area of Concern (AOC) in Sheboygan County, Wisconsin, contains the lower 22 kilometers of the Sheboygan River, including the Wildwood Islands complex, and it is the focus of remediation and restoration efforts by federal, state, and local governmental entities. Local hydrogeomorphic data is often used to aid in remediation and restoration project design. This dataset

The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bangor, Maine. The intention of this boresight is to provide an extensive array of high-accuracy ground control points for the

This dataset consists of trace organic contaminant concentrations and bacteria counts in wastewater effluents, and observed responses in fish exposed to effluents. The study was conducted from April to September 2022 at a facility located in Hutchinson, Minnesota. Nine pairs of primary-treated, activated sludge secondary treated, and membrane bioreactor secondary treated wastewater were

Private wells (n = 138) were sampled by large- and small-volume sampling methods in Grant, Iowa, and Lafayette Counties, Wisconsin, USA in 2019 and 2020. Well water samples were analyzed for microorganisms by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Gene targets for viruses, bacteria, and protozoa were analyzed, including...

Identifying how close species are to their current upper thermal limits estimates species sensitivity to climate change (or the species ability to persist in place without changing). Process-based models like the NicheMapR mechanistic niche model (Kearney et al. 2019; https://doi.org/10.1111/ecog.04680) use a mass-balance approach to translate microclimate estimates into individual...

This dataset describes mercury (Hg) concentrations and methylation rate potentials that were measured in Lake Mendota, Wisconsin, US in 2020 and 2021. This work is a collaboration between the University of Wisconsin, University of California-Davis, and the U.S. Geological Survey. Samples were collected to examine the linkages between Hg methylation, biogeochemical conditions, and...

This data release describes water service areas (WSA) for community water systems (CWS) within the conterminous United States, representing areas of active service between 2010 and 2020. A WSA is defined by a delineated polygon that contains all customers served by a water system. WSAs are represented by an ArcGIS shapefile. The U.S. Safe Drinking Water Act defines a CWS as a type of...

This data release contains 2 shapefiles which include 626 unique shorelines and 3 foredune toes spanning 2016 to 2023 along Minnesota Point, a 9-kilometer long bay-mouth bar at the western end of Lake Superior. Each shoreline represents the intersection line between land and water at a unique time associated with the capture of a satellite image, and these shorelines are used to examine...

A combined soil water balance, groundwater flow and stream temperature model was developed to simulate stream temperature under historical and future conditions. Soil-Water-Balance code was used to estimate net infiltration past the root zone and surface runoff, which were applied to a transient, three-dimensional MODFLOW 6 model to simulate the water budget for Beaver Creek and the...

Atmospheric mercury (Hg) deposition, which has been declining in North America since 1985, is the preeminent delivery pathway to the Great Lakes, making them sentinels for tracking shifts in atmospheric deposition. Lake productivity is changing as a result of reductions in phosphorus inputs and habitat shifts in productivity due to invasive mussels. This has altered Hg cycling and...

This data release contains supporting materials for a study testing the applicability of an image-derived water-level method at three U.S. Geological Survey (USGS) streamgage sites around Lake Redstone in Wisconsin (site numbers 05404140, 05404150, and 05404147) during Water Year 2020 (Johnson, et al., 2025). Two types of reference objects were tested in this study: white polyvinyl...

Phytoplankton samples were collected from Lake Pepin (a natural, riverine lake on the Upper Mississippi River) from 2012-2014. The dataset includes phytoplankton community data (i.e., genus, species, biovolume, etc.), as well as zooplankton, rotifer, cladoceran and water quality data.
