Exhibit 15-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of November 1, 2012.  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 15-B is for Water Year (WY) 2013 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 during October 2012 totaled 0.64 inches and brings the cumulative rainfall total for WY 2013 to 0.64 inches, which is 82% of the long-term average through October.  Estimated unimpaired runoff during October 2012 totaled 177 acre-feet (AF) and brings the cumulative runoff total for WY 2013 to 177 AF, which is 43% of the long-term average through October.  Usable storage, which includes surface and groundwater, was 27,820 AF, or 101% of the long-term average through October.  This storage equates to 74% of system capacity.  In addition, 0 adult steelhead were counted in the fish ladder at San Clemente Dam for WY 2013 through October.

 

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 10,187 AF of water from the Carmel River in WY 2013.  In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,669 AF of water from the Coastal Subareas and 147 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2013.  Altogether, Cal-Am is currently allowed to produce 13,003 AF from Carmel River and Seaside Coastal sources for customers in its main Monterey system and 147 AF from the Laguna Seca Subarea for customers in Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for ASR recovery or Sand City Desalination).  For WY 2013 through October, Cal-Am has produced 1,170 AF from the Carmel River, Seaside Basins, Sand City Desalination, and ASR recovery, for customer use.  This water production is 3 AF or 0.03% more than the target specified for Cal-Am’s production from the MPWRS for WY 2013 through October.  A breakdown of Cal-Am’s production for WY 2013 through October is included as Exhibit 15-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 2013 through October, 0 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use.  Exhibit 15-C  shows production breakdown from all sources for all uses.

 

Due to the timing of finalized data transmittal, some of the numbers in this report may be revised in the future.
