Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of August 1, 2024.  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) 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 July 2024 totaled 0.00 inches and brings the cumulative rainfall total for WY 2024 to 24.17 inches, which is 115% of the long-term average through July.  Estimated unimpaired runoff through May totaled 1,030 acre-feet (AF) and brings the cumulative runoff total for WY 2024 to 82,544 AF, which is 120% of the long-term average through July.  Usable storage for the MRWPRS was 28,220 acre-feet, which is 95% of average through July, and equates to 85% 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 2024.  Through July, using the CDO accounting method, Cal-Am has produced 2,453 AF from the Carmel River (excluding 410 AF of Table 13 and 57 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 2024.  Through July, Cal-Am has produced 1,408 AF from the Seaside Groundwater Basin.  Through July, 1,519 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 410 AF have been diverted under Table 13 water rights, and 2,791 AF of Pure Water Monterey recovered.  Cal-Am has produced 7,208 AF for customer use from all sources through July.  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.
