Data

These datasets includes physical and geochemical lab results of sediment samples collected from August 2017 to October 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Three sets of passive suspended-sediment samplers were installed and sampled monthly. Streambank and streambed sediment...

These datasets includes physical and geochemical lab results of sediment samples collected from October 2016 to February 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Passive suspended-sediment samplers were installed at three sites and sampled monthly. Streambank and streambed...

The East River is an agricultural tributary to the Lower Fox River and the Environmental Protection Agency (EPA) Green Bay Area of Concern (AOC) in northeast Wisconsin. This tributary has known excessive phosphorus (P) and suspended sediment loads that contribute to habitat related impairments and downstream algal blooms. As part of the Great Lakes Restoration Initiative (GLRI), the U.S

This dataset was compiled and analyzed to support the goals of quantifying groundwater contributions to Lake Huron and exploring the impacts of groundwater on Lake Huron processes in accordance with the Lake Huron Cooperative Science and Monitoring Initiative 2022 field season. This data release contains three child items that describe 1) the characterization of the Lake Huron Basin into

The monitoring of Lake Saint Clair Metropark beach involved several types of data collection. This data release includes data sets for the counts of avian species (gulls and Canada geese) and data on water fluxes between surface water and groundwater measured during recreational seasons of 2021, 2022, and 2023.

The U.S. Geological Survey Upper Midwest Water Science Center, in cooperation with the U.S. Coast Guard Great Lakes Oil Spill Center of Expertise and the Mashkiiziibii Natural Resources Department, completed bathymetric surveys of the lower Bad River, Kakagon River, Honest John Lake, and the Bad River Slough using multibeam and single beam echosounders from April 29 to May 1, 2025. This...

This U.S. Geological Survey (USGS) data release contains phytoplankton classification and enumeration results from near-surface water samples collected during a nationwide harmful algal bloom (HAB) monitoring effort in partnership with the National Park Service (NPS) Water Resources Division. Samples were collected during the 2021-2024 monitoring seasons from 26 National Parks across the...

The U.S. Geological Survey conducted a study in Milwaukee, Wisconsin, to evaluate the performance of a biofilter designed to treat urban stormwater runoff from a roadway. This data release includes load calculations for total suspended solids, nutrients, major ions, and 12 metals for monitoring that ran from March, 2022 to November, 2024. Loads are reported for both the inlet (USGS site...

As part of the larger Great Lakes Cooperative Science and Monitoring Initiative (CSMI) , the U.S. Geological Survey Mercury, Metals, and Microplastics Research Laboratory (USGS M3RL) completed a binational assessment partnering with the U.S. Environmental Protection Agency (US EPA), Environmental Climate Change Canada (ECCC), Ontario Ministry of Natural Resources and Forestry (ONRF)...

Linear regression models were developed using specific conductance to estimate chloride concentrations at stream and storm sewer sites monitored by the Upper Midwest Water Science Center (UMidWSC) for UMidWSC stakeholders. Methods for model development, application, and maintenance are described in Standard Operating Procedures for Computing Chloride Concentrations and Loads at Sites...

In cooperation with the City of Madison and the Madison Metropolitan Sewerage District (MMSD), the U.S. Geological Survey (USGS) has collected discrete storm sewer samples for analysis of chloride concentrations at a real-time streamflow and water-quality monitoring (specific conductance) station located at Spring Harbor Storm Sewer in Madison, Wisconsin (USGS station 05427965).
