This site is monitored as part of the USGS National Groundwater and Streamflow Information Program
This site is also monitored as part of the Minnesota Department of Natural Resources' Cooperative Groundwater Monitoring (CGM) Program.
Water level data collected during 26 Oct. 2016 to 20 Sept. 2018 were collected and published by the Minnesota Department of Natural Resources. These data were later archived and published in U.S. Geological Survey's National Water Information System (NWIS) database to lengthen the water level record for the U.S. Geological Survey's Climate-Response Network (CRN) Program.
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 0.1 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 0.1°C, and differences in temperature are accurate to 0.1°C
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.
