Exhibit 20-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of August 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 20-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 July 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 July.  Estimated unimpaired runoff through July totaled 516 acre-feet (AF) and brings the cumulative runoff total for WY 2025 to 33,522 AF, which is 49% of the long-term average through July.  Usable storage for the MRWPRS was 27,880 acre-feet, which is 94% of average through July, and equates to 84% 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 July, using the CDO accounting method, Cal-Am has produced 2,668 AF from the Carmel River (excluding 182 AF of Table 13 and 76 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 July, Cal-Am has produced 1,203 AF from the Seaside Groundwater Basin.  Through July, 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 3,086 AF of Pure Water Monterey recovered.  Cal-Am has produced 7,362 AF for customer use from all sources through July.  Exhibit 20-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.
