Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of December 1, 2023. 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 25-A is for Water Year (WY) 2024 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 November 2023 totaled 1.57 inches and brings
the cumulative rainfall total for WY 2024 to 1.72 inches, which is 61%
of the long-term average through November. Estimated unimpaired runoff through November totaled 531 acre-feet (AF)
and brings the cumulative runoff total for WY 2024 to 979 AF, which is 55% of the long-term average through November. Usable storage for the MRWPRS was 29,990 acre-feet, which is 108% of average through November, and equates to 91% 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 2023. Through September, using the CDO accounting method, Cal-Am has produced 2,417 AF from the Carmel River (excluding 511 AF of Table 13 and 92 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 2023. Through September, Cal-Am has produced 1,571 AF from the Seaside Groundwater Basin. Through September, 1,656 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 806 AF have been recovered for customer use, 511 AF have been diverted under Table 13 water rights, and 3,548 AF of Pure Water Monterey recovered. Cal-Am has produced 9,118 AF for customer use from all sources through September. Exhibit 25-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.
