The board received updates on the GSP amendment, targeting a public draft by September and public hearings around Nov/Dec with a 10% conservation reduction goal. About 2,500 fallowed vineyard acres are being tracked as temporary water savings with no permanent model changes yet. Modeling indicates minor subsidence in the eastern Cosumnes sub-basin, prompting enhanced monitoring and threshold review.
Satellite data indicated land subsidence east of Herald, and directors discussed it could lead to adjusted groundwater thresholds in the upcoming five-year GSP update. The board reviewed a recharge project operating at about 10% of permitted capacity and discussed grant options. A balanced $503,000 FY 2026–2027 budget was approved.
Board adopted the recharge project MND addendum (pump upgrades could raise diversion capacity from ~8,345 to ~20,500 gpm) and approved an interim amendment removing Sloughhouse RCD from the SASb MOU and updating cost shares. SASb costs drop next FY ($657,050 to $195,000) as managers opted not to do a full GSP update. Cosumnes and OHWD budgets were reviewed; action planned for June.
LAFCO annexation remains pending completion of the MSR, which staff said is waiting on a final accounting report; after annexation, the district expects to pursue a Prop 218 fee study for the expanded district. Recharge season was described as the most productive on record, with Rooney delivering ~150 acre-feet and Tiger estimated at roughly double that before cutoff dates passed.
The South American Subbasin remains in excellent condition with no undesirable results, adding 7,000 acre-feet of storage in the past year while staying well below sustainable yield. The first five-year SGMA periodic evaluation is underway with a draft targeted by the end of June. Recharge at Rooney has resumed after pump work, with operations continuing as long as flows remain adequate.
