2.5.2 Groundwater flow conceptual model representing
summer conditions
A second MODFLOW model has been developed for the winter months
(December-January-February) using conditions from winter (DJF) of
2015-2016. It uses a constant head North-South boundary of 4 mTAW and
the East-West boundary is a general head boundary which follows the mean
lake stage during this period. The pumping rate is set at 7,000
m3day-1 and the inflow rate to the
lake is 4,310 m3day-1. The mean
observed lake stage is 6.97 mTAW and pond bed leakance is 0.30
day-1.
