Exhibit 24-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of November 1, 2017.  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 24-A is for Water Year (WY) 2018 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 October 2017 totaled 0.15 inches and brings the cumulative rainfall total for WY 2018 to 0.15 inches, which is 19% of the long-term average through October.  Estimated unimpaired runoff during October totaled 554 acre-feet (AF) and brings the cumulative runoff total for WY 2018 to 554 AF, which is 19% of the long-term average through October.  Usable storage for the MRWPRS was 29,860 acre-feet, which is 103% of average through October, and equates to 79% 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 2018.  Through October, using the CDO accounting method, Cal-Am has produced 532 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 2018.  Through October, Cal-Am has produced 368 AF from the Seaside Groundwater Basin.  Through October, 0 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use, and 0 AF have been diverted under Table 13 water rights.  Cal-Am has produced 928 AF for customer use from all sources through October.  Exhibit 24-C  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.
