Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 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 23-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 September 2025 totaled 0.00 inches and brings the cumulative rainfall total for WY 2025 to 16.68 inches, which is 79% of the long-term average through August. Estimated unimpaired runoff through September totaled 262 acre-feet (AF) and brings the cumulative runoff total for WY 2025 to 34,178 AF, which is 50% of the long-term average through September. Usable storage for the MRWPRS was 26,440 acre-feet, which is 96% of average through September, and equates to 80% 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 September, using the CDO accounting method, Cal-Am has produced 3,291 AF from the Carmel River (excluding 182 AF of Table 13 and 83 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 September, Cal-Am has produced 1,684 AF from the Seaside Groundwater Basin. Through September, 716 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 182 AF have been diverted under Table 13 water rights, and 3,680 AF of Pure Water Monterey recovered. Cal-Am has produced 9,092 AF for customer use from all sources through September. Exhibit 23-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.
