    dct:description """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 with periods of below-normal 
precipitation but increases in groundwater withdrawals and land-use changes 
have put into question whether recent lake-water-level declines are due solely 
to declines in precipitation. The groundwater-flow model was developed to 
provide a thorough understanding of regional groundwater and surface-water 
exchanges under different groundwater withdrawal and precipitation scenarios.  
This USGS data release contains all of the input and output files for the 
simulations described in the associated U.S. Geological Survey Scientific 
Investigations Report 2016-5139B (https://doi.org/10.3133/sir20165139B).  
This data release also contains input and output data for ancillary soil-water 
balance (SWB) models used to simulate runoff to a subset of lakes and 
areal groundwater recharge.""" ;
