Legislative and Citizen's Commission on Minnesota Resources U.S. Fish & Wildlife Service-Glacial Ridge NWR Red Lake Watershed District The Nature Conservancy in Minnesota


During 2002–2015, this site was operated in cooperation with the U.S. Fish & Wildlife Service, Red Lake River Watershed District, The Nature Conservancy, and the Environment and Natural Resources Trust Fund.

Water levels below land surface are accurate to 0.01 feet. Water levels above North American Vertical Datum of 1988 (sea level) are calculated by subtracting recorded water levels from the land surface elevation, which is accurate to 0.07 feet based on a differential GPS survey. Water-level differences are accurate to within 0.01 feet.

Water temperature is accurate to plus-or-minus 1.0°C, and differences in temperature are accurate to 0.1°C

Water temperatures were recorded at 13.1 feet below land surface during 23 Oct. 2002 to 18 Oct. 2016. Beginning on 18 Oct. 2016, the transducer was repositioned in the well and began recording water temperature data at 12.7 feet below land surface.

Precipitation is accurate to 0.01 inches except during freezing periods (about Dec. through early Apr.). The rain gage is unheated and uncovered. The precipitation data during freezing periods result from melting of snow (accumulated in the rain gage) during warm periods and do NOT represent actual precipitation. Precipitation totals during freezing periods may underestimate actual totals because the rain gage funnel may be full of snow (preventing further accumulation) or because snow in the funnel may sublimate instead of melt.

This station managed by the Mounds View Field Office.
