Minnesota
In 1911, USGS personnel began measuring streamflow to aid in operation of reservoirs on the Mississippi River. From that fledgling start, the USGS Upper Midwest Water Science Center now provides data and interpreted science to more than 30 partners in federal, state, county and local governments to help manage and protect Minnesota’s groundwater and surface-water resources.

Transport of nitrogen and phosphorus in the Cedar River Basin, Iowa and Minnesota, 2000–15
Nitrate concentrations in the Cedar River in Iowa and Minnesota have increased from an average of less than 1.0 milligram per liter in the early 1900s to more than 5.0 milligrams per liter in the 2000s and have resulted in periodic water-quality impairment of the river. Spatial differences and temporal changes in nitrogen and phosphorus transport...

Constraining the thermal history of the North American Midcontinent Rift System using carbonate clumped isotopes and organic thermal maturity indices
The Midcontinent Rift System (MRS) is a Late Mesoproterozoic (∼1.1 Ga) sequence of volcanic and sedimentary rocks exposed in the Lake Superior Region of North America. The MRS continues to be the focus of much research due to its economic mineral deposits as well as its archive of Precambrian life and tectonic processes. In order to constrain...
Gallagher, Timothy M.; Sheldon, Nathan D.; Mauk, Jeffrey L.; Petersen, Sierra V.; Gueneli, Nur; Brocks, Jochen J. Mercury and water level fluctuations in lakes of northern Minnesota

However, many northern temperate fisheries are contaminated by mercury. Annual variation in mercury accumulation in fish has previously been linked to water level (WL) fluctuations, opening the possibility of...

Water Quality Across Regional Stream Networks: The Influence of Land Cover and Land Use, Climate, and Biogeochemical Processing on Spatiotemporal Variance
Land cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. As LC/LU and climate continue to change we can expect changes in water quality. This project seeks to understand the drivers of spatial and temporal variability in water quality across scales using new and existing data to...
Ecoflows: Developing Indices of Streamflow Alteration
The Minnesota Pollution Control Agency (MPCA) lists streamflow alteration as a key stressor on aquatic life in many watersheds. However, the MPCA currently does not have the information needed to quantitatively associate metrics from Index of Biological Integrity (IBI) surveys with metrics of streamflow alteration. We are using USGS streamgage data and MPCA IBI data to develop relations...
Chemicals of Concern in the Great Lakes Basin
The Great Lakes are an important freshwater source of drinking water, fisheries, and habitat. Chemicals of concern are introduced to the environment by human activities, but resulting ecological consequences are little understood. With federal and University partners, we are characterizing the presence of contaminants and potential effects to fish in Great Lakes tributaries.
Development of a FluEgg Model for the St. Croix River
The USGS partnered with the Minnesota Department of Natural Resources to collect hydraulic and water chemistry data in the lower St. Croix River for development of a model that predicts the probability of successful egg hatching and survival of juvenile invasive carp over a range of water temperature and streamflow conditions.
Arsenic in Minnesota groundwater—Occurrence and relation to hydrogeologic and geochemical factors
Geologic-sourced arsenic is common in Minnesota groundwater. Drinking-water managers, well owners, and well contractors need to know where and why high arsenic in groundwater is likely to occur in wells in order to take measures to protect public health. The USGS is assessing the spatial distribution of high arsenic groundwater in Minnesota, and identifying factors affecting arsenic...
Assessing Hydrologic Changes in the St. Louis River Basin from Past Land Uses
Resource managers can use assessments of past and future land use to make science-based decisions. This project characterizes how changes in land use can change groundwater and surface-water flows in the St. Louis River Basin, MN. The USGS is constructing a set of groundwater models to simulate groundwater/surface-water interactions and evaluate how water flows have changed.
Measuring Suspended-Sediment Concentrations, Grain Sizes and Bedload using Acoustic Doppler Velocity Meters and Echologgers in the Lower Chippewa River, Wisconsin
Sediment from the Chippewa River deposits in the Mississippi River navigation channel, sometimes disrupting commercial barge traffic and resulting in expensive and ecologically disruptive dredging operations. The USGS is using new applications of hydroacoustic technologies to better understand sediment transport in the Chippewa River and associated effects on commercial navigation.
Continuous Groundwater Monitoring Network - Minnesota
