Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of May 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 23-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 April 2023 totaled 0.15 inches and brings the cumulative rainfall total for WY 2023 to 34.61 inches, which is 169% of the long-term average through April.  Estimated unimpaired runoff through April totaled 23,390 acre-feet (AF) and brings the cumulative runoff total for WY 2023 to 197.092 AF, which is 314% of the long-term average through April.  Usable storage for the MRWPRS was 32,080 acre-feet, which is 102% of average through April, and equates to 102% 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 April, using the CDO accounting method, Cal-Am has produced 894 AF from the Carmel River (excluding 410 AF of Table 13 and 53 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 April, Cal-Am has produced 812 AF from the Seaside Groundwater Basin.  Through April, 1,250 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 2,675 AF of Pure Water Monterey recovered.  Cal-Am has produced 4,936 AF for customer use from all sources through April.  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.
