Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of March 1, 2016.  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 23-A is for Water Year (WY) 2015 and focuses on four factors: rainfall, runoff, storage, and steelhead.  The rainfall and Streamflow values are based on measurements in the upper Carmel River Basin at San Clemente Dam. 

 

Water Supply Status:  As shown, rainfall through February 2016 totaled 1.69 inches and brings the cumulative rainfall total for WY 2016 to 16.00 inches, which is 104% of the long-term average through February.  Estimated unimpaired runoff during February 2016 totaled 4,049 acre-feet (AF) and brings the cumulative runoff total for WY 2016 to 15,513 AF, which is 43% of the long-term average through February.  Usable storage, which includes surface and groundwater, was 30,560 or 97% of the long-term average at the beginning of March.  This storage equates to 81% of system capacity. 

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2009-0060, California American Water (Cal-Am) is allowed to produce no more than 9,703 AF of water from the Carmel River in WY 2016.  In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,251AF of water from the Coastal Subareas and 48 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2016.  Altogether, Cal-Am is currently allowed to produce 11,954 AF from Carmel River and Seaside Coastal sources for customers in its main Monterey system and 48 AF from the Laguna Seca Subarea for customers in Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for Sand City Desalination).  For WY 2016 through February, Cal-Am has produced 3,781 AF from the Carmel River (including ASR and Table 13), Seaside Basin, and Sand City Desalination.  This water production is 601 AF or 13.9 % less than the target specified for Cal-Am’s production from the MPWRS for WY 2016 through February.  A breakdown of Cal-Am’s production for WY 2016 through February is included as Exhibit 23-B.  Cal-Am’s production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin; Cal-Am’s “native” Seaside Basin production is reduced for injected water recovery. For WY 2016 through February, 270.0 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use.  Exhibit 23-C shows production breakdown from all sources for all uses.  Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
