Exhibit 26-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of June 1, 2025. This system includes the surface water resources in the Carmel River Basin, the groundwater resources in the Carmel Valley Alluvial Aquifer and the Seaside Groundwater Basin. Exhibit 26-A is for Water Year (WY) 2025 and focuses on three factors: rainfall, runoff, and storage. The rainfall and Streamflow values are based on measurements in the upper Carmel River Basin at Sleepy Hollow Weir.
Water Supply Status: Rainfall through May 2025 totaled 0.11 inches and brings the cumulative rainfall total for WY 2025 to 16.67 inches, which is 80% of the long-term average through May.
Estimated unimpaired runoff through May
totaled 1,620 acre-feet (AF) and brings the cumulative runoff total for
WY 2025 to 32,105 AF, which is 48% of the long-term average through May. Usable storage for the
MRWPRS was 29,380 acre-feet, which
is 94% of average through April, and equates to 89 percent of system capacity.
Production Compliance: Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2016-0016 (CDO), California American Water (Cal-Am) is allowed to produce no more than 3,376 AF of water from the Carmel River in WY 2025. Through April, using the CDO accounting method, Cal-Am has produced 2,062 AF from the Carmel River (excluding 183 AF of Table 13 and 55 AF of Mal Paso.) In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 1,474 AF of water from the Coastal Subareas and 0 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2025. Through May, Cal-Am has produced 980 AF from the Seaside Groundwater Basin. Through May, 716 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 183 AF have been diverted under Table 13 water rights, and 2,238 AF of Pure Water Monterey recovered. Cal-Am has produced 5,639 AF for customer use from all sources through May. Exhibit 26-B shows production by source. Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
