Exhibit 43-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of June 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 43-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 May 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 May.  Estimated unimpaired runoff through May totaled 779 acre-feet (AF) and brings the cumulative runoff total for WY 2021 to 15,821 AF, which is 24% of the long-term average through May.  Usable storage for the MRWPRS was 27,890 acre-feet, which is 90% of average through May, and equates to 84% 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 May, using the CDO accounting method, Cal-Am has produced 3,033 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 May, Cal-Am has produced 1,018 AF from the Seaside Groundwater Basin.  Through May, 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 1,906 AF of Pure Water Monterey recovered.  Cal-Am has produced 5,954 AF for customer use from all sources through May.  Exhibit 43-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.
