Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of July 1, 2021.  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) 2021 and focuses on four 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 June 2021 totaled 0.00 inches and brings the cumulative rainfall total for WY 2021 to 10.85 inches, which is 52% of the long-term average through June.  Estimated unimpaired runoff through June totaled 313 acre-feet (AF) and brings the cumulative runoff total for WY 2021 to 16,134 AF, which is 24% of the long-term average through June.  Usable storage for the MRWPRS was 26,770 acre-feet, which is 89% of average through June, and equates to 81% 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 7,310 AF of water from the Carmel River in WY 2021.  Through June, using the CDO accounting method, Cal-Am has produced 3,443 AF from the Carmel River (including ASR capped at 600 AF, Table 13, and 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 2021.  Through June, Cal-Am has produced 1,080 AF from the Seaside Groundwater Basin.  Through June, 66 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 17 AF have been diverted under Table 13 water rights, and 2,330 AF of Pure Water Monterey recovered.  Cal-Am has produced 6,873 AF for customer use from all sources through June.  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.
