Snowpack is critically low at just 18% of the April 1 average, driven by a warm, dry March that accelerated snowmelt. However, Don Pedro Reservoir is at 92% capacity (elevation 817.02 ft) with MID's share at ~495,666 acre-feet; combined MID storage (Don Pedro + Modesto Reservoir) is 513,734 acre-feet, higher than last year's ~503,000 combined total. The year-end storage forecast has improved significantly from the last report (projected elevation 774 vs. previously projected 763), and staff indicated the forecast may improve further based on updated data from Hetch Hetchy partners. Irrigation season deliveries to date total 15,733 acre-feet with groundwater pumping at 1,116 acre-feet (60% shallow wells, 40% production wells).
