No allocation update is expected in July despite above-average storage; Jones pumping may be limited to one unit by high tides, and directors asked for a formal advocacy update next month. DMC subsidence correction construction is underway and on schedule, while golden mussels spread north with new detections and growing operational costs expected to become recurring budget items.
Produced water reuse deliveries began June 22, with flows currently at 0.3 cfs and long-term expectations of 0.6–0.8 cfs. Golden mussel treatment is ongoing with no mussels detected within district boundaries, and county-wide response costs have surpassed $7.3 million. A TNDLA draft groundwater allocation options analysis was reviewed (no policies set); program rollout discussed as 2028 or later.
Land subsidence was found to be minimal based on InSAR data; Todd Groundwater reported DWR said no changes to subsidence criteria are needed until a 2032 reevaluation. Analysis concluded that temporarily lowering groundwater levels to interim milestones is unlikely to significantly affect groundwater dependent ecosystems near the Stanislaus and Tuolumne Rivers. The county reported it is finalizing a third-party contract for the Non-District East action plan, targeting July 14 board approval.
Zanjero presented a groundwater consumption methodology using OpenET minus effective precipitation and surface water deliveries, with methodology lock-in aimed for August. Effective precipitation proposes a single basin-wide average from four CIMIS stations. The Board unanimously approved Woodard & Curran's scope to respond to DWR comments; funding options are expected to return at a future meeting.
Water deliveries are near full capacity with almost 4,000 acre-feet scheduled for July, and a final 10,400 acre-feet transfer to Lower Tule will occur in July. Golden mussels were discussed; speakers said they have not been detected this far north yet, but staff noted uncertainty. Staff said the district agreed to a Nov. 1 canal shutoff date and expects to be on the new canal when deliveries resume at the end of January.
