Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of January 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 25-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 December 2020 totaled 0.94 inches and brings the cumulative rainfall total for WY 2021 to 1.48 inches, which is 22% of the long-term average through December.  Estimated unimpaired runoff through December totaled 652 acre-feet (AF) and brings the cumulative runoff total for WY 2021 to 1,656 AF, which is 24% of the long-term average through December.  Usable storage for the MRWPRS was 28,920 acre-feet, which is 100% of average through December, and equates to 87% 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 December, using the CDO accounting method, Cal-Am has produced 852 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 December, Cal-Am has produced 760 AF from the Seaside Groundwater Basin.  Through December, 0 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 0 AF have been diverted under Table 13 water rights, and 700 AF of Pure Water Monterey recovered.  Cal-Am has produced 2,329 AF for customer use from all sources through November.  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.
