The Anoka Conservation District is part of the Minnesota Department of Natural Resource's effort to track groundwater levels. The MN DNR maintains a network of groundwater observation wells across the state. These deep groundwater wells are not as sensitive to precipitation as other hydrologic systems such as wetlands and streams, but rather, respond to longer term trends. The ACD is contracted to take monthly water level readings at 14 wells in Anoka County during March - December. The MN DNR incorporates these data into a statewide database that aids in groundwater mapping.
The data are reported by the MN DNR on their web site. To see the locations of the monitoring sites, use the mapping utility and check the "monitor sites" box.
