Exhibit 26-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of August 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 26-A is for Water Year (WY) 2023 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 2023 totaled 0.00 inches and brings the cumulative rainfall total for WY 2023 to 35.19 inches, which is 167% of the long-term average through July. Estimated unimpaired runoff through June totaled 1,530 acre-feet (AF) and brings the cumulative runoff total for WY 2023 to 107,792 AF, which is 303% of the long-term average through July. Usable storage for the MPWRS was 29,860 acre-feet, which is 100% of average through June, and equates to 90% 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 July, using the CDO accounting method, Cal-Am has produced 1,855 AF from the Carmel River (excluding 511 AF of Table 13 and 78 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 July, Cal-Am has produced 1,812 AF from the Seaside Groundwater Basin. Through July, 1,855 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 284 AF have been recovered for customer use, 511 AF have been diverted under Table 13 water rights, and 2,707 AF of Pure Water Monterey recovered. Cal-Am has produced 7,400 AF for customer use from all sources through July. 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.
