Exhibit 27-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of April 1, 2022.  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 27-A is for Water Year (WY) 2022 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 March 2022 totaled 1.69 inches and brings the cumulative rainfall total for WY 2022 to 11.65 inches, which is 62% of the long-term average through March.  Estimated unimpaired runoff through March totaled 1,427 acre-feet (AF) and brings the cumulative runoff total for WY 2022 to 20,198 AF, which is 38% of the long-term average through March.  Usable storage for the MRWPRS was 28,230 acre-feet, which is 91% of average through March, and equates to 85% 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 4,110 AF of water from the Carmel River in WY 2022.  Through March, using the CDO accounting method, Cal-Am has produced 2,113 AF from the Carmel River (including ASR capped at 600 AF in, Table 13, and Mal Paso in Calendar Year 2022.)  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 2022.  Through March, Cal-Am has produced 294 AF from the Seaside Groundwater Basin.  Through March, 71 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, 68 AF have been diverted under Table 13 water rights, and 1,859 AF of Pure Water Monterey recovered.  Cal-Am has produced 4,265 AF for customer use from all sources through March.  Exhibit 27-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.
