Unified Interior Regions
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.

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...
