Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of January 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) 2016 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 December 2015 totaled 4.17 inches and brings the cumulative rainfall total for WY 2016 to 8.16 inches, which is 120% of the long-term average through December.  Estimated unimpaired runoff during December 2015 totaled 1,186 acre-feet (AF) and brings the cumulative runoff total for WY 2016 to 1,449 AF, which is 21% of the long-term average through December.  Usable storage, which includes surface and groundwater, was 25,440, or 88% of the long-term average through December.  This storage equates to 68% of system capacity.  In addition, 0 adult steelhead were counted in the fish ladder at San Clemente Dam through December.

 

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 ASR recovery or Sand City Desalination).  For WY 2016 through December, Cal-Am has produced 2,177 AF from the Carmel River, Seaside Basin, Sand City Desalination, and ASR recovery, for customer use.  This water production is 598 AF or 21.6 % less than the target specified for Cal-Am’s production from the MPWRS for WY 2016 through December.  A breakdown of Cal-Am’s production for WY 2016 through December 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 December, 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.
