1. Greater Kaweah GSA Overdraft Allocation Under Scrutiny — Sub-Basin Implications for TID Growers The Greater Kaweah GSA recently changed its rules to allow transfer of native safe yield (the 10-inch allocation) anywhere within its boundaries, which TID flagged as a serious concern because it could enable pumping from areas underlain by the Corcoran Clay — a one-way ratchet for subsidence. TID has communicated to Greater Kaweah that the district expects — not merely supports — elimination of overdraft allocation. Greater Kaweah's stakeholder committee is now discussing a proposal to phase out overdraft allocation by 2027, replacing it with purchased surface water or groundwater credits. The outcome will directly affect groundwater sustainability and pumping conditions across the Kaweah Sub-basin.
