Exhibit 22-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of March 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 22-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 February 2023 totaled 3.55 inches and brings the cumulative rainfall total for WY 2023 to 27.25 inches, which is 176% of the long-term average through February.  Estimated unimpaired runoff through February totaled 13,720 acre-feet (AF) and brings the cumulative runoff total for WY 2023 to 105,232 AF, which is 283% of the long-term average through February.  Usable storage for the MRWPRS was 32,580 acre-feet, which is 102% of average through February, and equates to 98% 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 February, using the CDO accounting method, Cal-Am has produced 796 AF from the Carmel River (excluding 212 AF of Table 13 and 38 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 February, Cal-Am has produced 353 AF from the Seaside Groundwater Basin.  Through February, 605 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 212 AF have been diverted under Table 13 water rights, and 1,875 AF of Pure Water Monterey recovered.  Cal-Am has produced 3,343 AF for customer use from all sources through February.  Exhibit 22-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.
