DNR/MPCA Cooperative Stream Gaging

We need your help! Please help us make the new CSG website better by completing a short survey.


-- CSG Project Team

This water data resource site provides access to near real-time and historical streamflow and water quality data. Select a gage and follow the link in the "CSG Site View" window to obtain detailed information.

  • Use map tools to navigate and select a gage on the Map View tab. LakeFinder information is also available in Map View by selecting a lake.
  • View data in a tabular format on the Table View tab.
  • Customize gages shown in the display using tools on the Filters tab.

Map navigation/selection: Use map navigation tools to zoom in, zoom out, pan, and identify gages. Select a gage you are interested in by clicking on the point and following the link in the CSG Site View window. The Filters tab may be used to determine which sites are mapped. Base map appearance may be altered using the Legends tab.


About the map: Real-time stations are shown on the map reflecting streamflow conditions as a percentile ranking for the current day of the year. These statistics are only computed for stations with at least 10 years of record. Sites may be unranked because they have fewer than 10 years of record or they report parameters other than streamflow.
