Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of April 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 March 2025 totaled 3.95 inches and brings the cumulative rainfall total for WY 2025 to 15.98 inches, which is 85% of the long-term average through March.  Estimated unimpaired runoff through March totaled 8,090 acre-feet (AF) and brings the cumulative runoff total for WY 2025 to 26,225 AF, which is 49% of the long-term average through March.  Usable storage for the MRWPRS was 30,220 acre-feet, which is 95% of average through March, 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 2025.  Through March, using the CDO accounting method, Cal-Am has produced 1,264 AF from the Carmel River (excluding 163 AF of Table 13 and 46 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 March, Cal-Am has produced 757 AF from the Seaside Groundwater Basin.  Through March, 637 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 163 AF have been diverted under Table 13 water rights, and 1,797 AF of Pure Water Monterey recovered.  Cal-Am has produced 4,123 AF for customer use from all sources through March.  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.
