Current data is updated each workday, normally by 11:00am CT.
All data is provisional and may be revised at a later date.
The level of Shoal Lake is being provided when available due to the ongoing configuration of the new gauge site.
Rapid River is currently under backwater conditions from a beaver dam downstream and because of this the USGS is suppressing the flow data. No flow will be available in our reports until conditions change.
See Notes below regarding data sources and file format.

    Notes
  •  
    		•  The data in these reports and graphs is from a variety of sources, including the following: Water Survey Canada (water level and flow gauges in Ontario and Manitoba), Meteorological Service of Canada (precipitation and temperature data); Ontario Ministry of Natural Resources and Forestry (precipitation data); United States Geological Survey (water levels and flows in Minnesota); US Army Corps of Engineers (water levels in Minnesota); H2O Power LP (water level and flow data from dams in Ontario), PCA (water level and flow data from dam in International Falls), Manitoba Hydro (water level and flow data from dams in Manitoba) and Ontario Power Generation (water level and flow data from dams in Ontario); volunteers (precipitation data in Ontario and Minnesota). Inflow for the major lakes is computed by the LWCB, as are all statistics.
