No allocation at this time - The groundwater agency has not yet adopted groundwater pumping allocations; the draft program proposes overlying allocations of 0.45 af/ac for all non-urban lands and example totals by management area, but these remain draft until formal adoption expected in 2026. - The draft program includes response triggers that allow the GSA to activate management-area action plans and impose enforceable allocations beginning in 2027 if groundwater levels decline or pumping exceeds the example targets. Districted Areas (MID + OID) – Overlying allocation: 0.45 af/ac – Developed supply (district-controlled, not per-acre): MID 90,900 AF; OID 31,600 AF.
