A three-dimensional, steady-state groundwater-flow model representing 2003-13 mean hydrologic conditions was developed and calibrated to assess groundwater and lake-water exchanges and the effects of groundwater withdrawals and precipitation on water levels in lakes in the northeast Twin Cities Metropolitan Area, Minnesota. The USGS groundwater-flow model program MODFLOW-NWT version 1.0.8 was used to simulate groundwater flow in the approximately 1,000-square-mile area of the northeast Twin Cities Metropolitan Area and western Wisconsin. Water levels were below normal for several lakes in the northeast Twin Cities Metropolitan Area during 2003 through 2013. Previous periods of low lake-water levels generally correlate...
This groundwater-flow model archive contains heuristic model simulations evaluating the sustainability of groundwater withdrawals from public-water-supply wells on buried glacial aquifers. A total of 40 steady-state simulations and three transient simulations were run. The steady-state simulations were developed to assess the extent and connections between buried sand aquifers by varying three hydraulic or dimensional properties of the buried aquifer or overlying tills over a range of values observed in field sites near the cities of Akeley, Cromwell, Litchfield, and Olivia, Minnesota.
