Exhibit 13-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of July 1, 2023.  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 13-A is for Water Year (WY) 2023 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 June 2023 totaled 0.17 inches and brings the cumulative rainfall total for WY 2023 to 35.19 inches, which is 168% of the long-term average through June.  Estimated unimpaired runoff through June totaled 2,130 acre-feet (AF) and brings the cumulative runoff total for WY 2023 to 206,262 AF, which is 304% of the long-term average through June.  Usable storage for the MRWPRS was 30,180 acre-feet, which is 101% of average through June, and equates to 91% 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 3,376 AF of water from the Carmel River in WY 2023.  Through June, using the CDO accounting method, Cal-Am has produced 1,411 AF from the Carmel River (excluding 511 AF of Table 13 and 65 AF of 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 2023.  Through June, Cal-Am has produced 1,414 AF from the Seaside Groundwater Basin.  Through June, 1,656 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 206 AF have been recovered for customer use, 511 AF have been diverted under Table 13 water rights, and 2,675 AF of Pure Water Monterey recovered.  Cal-Am has produced 6,506 AF for customer use from all sources through June.  Exhibit 13-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.
