    dct:description """A regional groundwater flow model (https://pubs.usgs.gov/sir/2009/5244/) was updated to reflect 2017 
pumping conditions in the Tri-County Region covering most of Clinton, Eaton, and Ingham Counties, 
Michigan. This model was developed to simulate the regional hydrologic system in Tri-County area 
and continues to be used for planning and protection of area water supplies. Revised contributing area 
delineations in response to recent pumping conditions were needed for local wellhead protection area 
programs. The model was calibrated to water level observations for 2017 from well driller logs, average 
water levels for 2012-17 from active USGS observation wells, and estimated baseflow for 2012-16 from 
USGS streamgaging station measurements. The model was used to delineate 10- and 40-year 
contributing areas to selected wells in Lansing and East Lansing, Michigan. This USGS data release 
contains all of the input and output files for the MODFLOW and MODPATH simulations described in 
the associated model documentation report (https://doi.org/10.3133/ofr20181133).""" ;
