1. Basin is Drying Out Fast — Zero Rain in March and Groundwater Levels Declining After receiving only 9.74 inches of precipitation in Water Year 2025 (47% of the long-term average), Kear reported the basin has seen zero rainfall through March 2026 to date. Groundwater storage decreased by approximately 5,495 acre-feet over WY2025, and current groundwater levels have started declining from a peak of 48.44 ft to water on March 7. Surface flows in tributary creeks like Thatcher and Stewart Canyon are dry or nearly dry, and San Antonio Creek outflow has dropped to just over 9 cfs. The basin remains at roughly 96% storage capacity (76,800 AF), but the trend is clearly downward heading into summer.
