Minnesota Water Science Center Activity on Twitter
The USGS Minnesota Water Science Center continuously monitors surface water, ground water, and water quality parameters across the state. Monitoring sites are operated in cooperation with various local, State, or Federal agencies.
Minnesota provides real-time water-stage, streamflow and precipitation data at 149 sites across the state.
33 ground-water wells are monitored by the USGS in Minnesota. These wells record data on hourly intervals.
Water-quality conditions are continuously monitored by the USGS at 11 sites across the state of Minnesota

Floods of June 2012 in Northeastern Minnesota
This report documents the magnitude and extent of flooding in northeastern Minnesota following heavy rainfall during June 19-20, 2012. Widespread flash and river flooding caused evacuations of residents, and damages to residences, businesses, and infrastructure. Peak-of-record streamflows were recorded at 13 of 35 U.S. Geological Survey streamgages in the nine counties in northeastern Minnesota with disaster declarations due to the flooding. Flood-peak streamflows in June 2012 had annual exceedance probabilities estimated to be less than 0.002 (0.2 percent; recurrence interval greater than 500 years) for five streamgages, and between 0.002 and 0.01 (1 percent; recurrence interval greater than 100 years) for four streamgages. High-water marks were collected to represent the flood-peak water-surface profile within the most severely affected communities of Barnum (Moose Horn River), Carlton (Otter Creek), Duluth Heights neighborhood of Duluth (Miller Creek), Fond du Lac neighborhood of Duluth (St. Louis River), Moose Lake (Moose Horn River and Moosehead Lake), and Thomson (Thomson Reservoir outflow near the St. Louis River). Flood-peak inundation maps were constructed in a geographic information system by combining high-water-mark data with high-resolution digital elevation model data. The flood maps and profiles show the extent and depth of flooding through the communities and can be used for flood response and recovery efforts by local, county, State, and Federal agencies.
Data via GoogleMaps
New Maps Deliver Current Streamflow Conditions
We added a Google-Map based Web page to deliver map-based current surface-water resources conditions in Minnesota.
The maps utilize zoom and pan to allow you to focus in on the water-monitoring sites that interest you. The maps show current streamflow as compared to historical records. By hovering your mouse over a site, a popup box shows the most recent stage and streamflow.
News from the MNWSC
White Bear Lake Project in the News
The White Bear Press has released an article describing the start of the second phase of the White Bear Lake Project, expanding the study to other northeast Twin Cities Metropolitan Area lakes. A team of scientists conducted seismic surveys in White Bear and five other northeast Twin Cities Metropolitan Area lakes in mid-November to look for changes in the geology of lake bottom sediments that may indicate areas of potential seepage into lower aquifers.
Report Published: Evaluation of internal loading and water level changes: implications for phosphorus, algal production, and nuisance blooms in Kabetogama Lake, Voyageurs National Park, Minnesota
The U.S. Geological Survey, Minnesota Water Science Center is pleased to announce a new publication, "Evaluation of internal loading and water level changes: implications for phosphorus, algal production, and nuisance blooms in Kabetogama Lake, Voyageurs National Park, Minnesota" by Victoria Christensen and Richard Kiesling (USGS) and Ryan Maki (National Park Service). The publication in the Journal of Lake and Reservoir Management highlights how dam operations have the potential to affect water quality in reservoirs. Dam operations at Kabetogama Lake were modified in 2000 to restore a more natural water regime and improve water quality. The U.S. Geological Survey and National Park Service evaluated nutrient, algae, and nuisance bloom data in relation to changes in Kabetogama Lake water levels. Water and sediment data were collected at Voyageurs National Park during 2008-2009 to assess internal phosphorus loading, that is phosphorus released from the bottom sediments, and determine whether this is a factor affecting phosphorus concentrations and algal productivity. Stratification in certain areas, higher bottom water and sediment nutrient concentrations than in other parts of the lake, and phosphorus release rates estimated from sediment core incubations indicated that Lost Bay on the northern side of Kabetogama Lake is one of several areas that may be contributing to internal loading. Internal loading of phosphorus is a concern because increased phosphorus may cause excessive algal growth including potentially toxic cyanobacteria. Comparison of the results of this study to previous studies indicates that chlorophyll a concentrations have decreased, whereas total phosphorus concentrations have not changed significantly since 2000.

Report Published: Mercury in wetlands at the Glacial Ridge National Wildlife Refuge, northwestern Minnesota, 2007-9
A new report on mercury in wetlands at the Glacial Ridge National Wildlife Refuge was published on June 3. The largest wetland and prairie restoration in United States history recently was completed at the Refuge. More than 3000 acres of wetlands were restored, more than 100 miles of ditches were filled, and nearly 18,000 acres of land was reseeded with native prairie plants. Microbial conversion of inorganic mercury to the bioaccumulative methylmercury form is a particularly active process in wetlands, making wetlands important methylmercury "hotspots" on the landscape. Concentrations of methylmercury in the Glacial Ridge NWR wetlands are among some of the highest in the published literature, suggesting seasonal wetlands of northwestern Minnesota are "hotspots" for mercury methylation, and may be a potential concern for wildlife.
Theatened Gage Notice For Minnesota
Due to sequestration a 5.2 percent decrease in funding for the U.S. Geological Survey's National Streamflow Information Program resulted in the discontinuation of three streamgages in Minnesota, including:
Funding for the latter two streamgages has been picked up by the Minnesota Department of Natural Resources through Sept. 30, 2013.
Low water in lakes, wells, aquifers surrounding Twin Cities could be big problem
The Pioneer Press has released an article discussing recent findings from the White Bear Lake study as well as broader implications for the state.
Minnesota draining its supplies of water
A recent StarTribune article discusses concerns and solutions to declining water levels that have become a new normal throughout Minnesota.
Minnesotans pay a price for crop fertilizer at the faucet
As crops spread, some land can no longer cleanse nitrates from groundwater. The Minnesota Department of Agriculture is now devising a range of solutions.
Four new water level gauges target Cannon River flooding
To make more accurate flood forecasts and give people more warning of high water, four new water level gauges are being installed for $70,000.
Low-flying aircraft will track potential mineral and water resources in Iowa and Minnesota
U.S. Geological Survey scientists plan to conduct the first comprehensive, high-resolution airborne survey to study the rock layers under a region of Northeastern Iowa and Southeastern Minnesota. When the data analysis is complete, resulting state-of-the-art, 3-D subsurface maps will help USGS researchers improve an assessment of mineral and water resources of the region.
