Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2020.  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 25-A is for Water Year (WY) 2020 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 September 2020 totaled 0.00 inches and brings the cumulative rainfall total for WY 2020 to 17.57 inches, which is 83% of the long-term average through September.  Estimated unimpaired runoff through September totaled 254 acre-feet (AF) and brings the cumulative runoff total for WY 2020 to 46,212 AF, which is 69% of the long-term average through September.  Usable storage for the MRWPRS was 26,730 acre-feet, which is 95% of average through September, 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 8,310 AF of water from the Carmel River in WY 2020.  Through September, using the CDO accounting method, Cal-Am has produced 7,025 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 1,820 AF of water from the Coastal Subareas and 0 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2020.  Through September, Cal-Am has produced 2,218 AF from the Seaside Groundwater Basin.  Through September, 917 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 753 AF have been recovered for customer use, and 218 AF have been diverted under Table 13 water rights.  Cal-Am has produced 9,592 AF for customer use from all sources through September.  Exhibit 25-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.  The 12-month moving average of production for customer service is 9,592 AF, which is below the rationing trigger of 10,130 AF for WY 2020.
