Exhibit 20-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of March 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 20-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 February 2024 totaled 6.47 inches and brings the cumulative rainfall total for WY 2024 to 15.94 inches, which is 103% of the long-term average through February.  Estimated unimpaired runoff through January totaled 3,190 acre-feet (AF) and brings the cumulative runoff total for WY 2024 to 20,760 AF, which is 71% of the long-term average through February.  Usable storage for the MRWPRS was 29,760 acre-feet, which is 94% of average through February, 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 2024.  Through February, using the CDO accounting method, Cal-Am has produced 1,081 AF from the Carmel River (excluding 117 AF of Table 13 and 30 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 February, Cal-Am has produced 631 AF from the Seaside Groundwater Basin.  Through February, 478 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 117 AF have been diverted under Table 13 water rights, and 1,622 AF of Pure Water Monterey recovered.  Cal-Am has produced 3,512 AF for customer use from all sources through February.  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.
