4/18/2019 KSB Basin Setting Status • KSB Managers and GSA TAC recently completed review of December 1, 2019 Draft Basin Setting • Approved Amended Task Order KSB-05.2018 – Basin Setting at February Meeting • GEI Team has incorporate KSB Managers comments addressing these issues: 1. Decrease Kaweah River and CVP Water deliveries 2. Decrease Mountain Front Recharge in EKGSA and portions of GKGSA 3. Recalculate percolation or precipitation and applied water during period 1981-1999 using different methodology 4. Improve boundary flux estimates using numerical groundwater model 5. Document the specific yield method for calculating change in groundwater basin storage Revised Water Budgets Each of these three water budgets periods have been refined with the recent Basin Setting Update • Historic Period – 1981 to 2017 • Current Period – 1997 to 2017 • Projected Future – 2017 to 2070 2
