Exhibit 26-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2008.  This system includes the surface water resources in the Carmel River Basin, the ground water resources in the Carmel Valley Alluvial Aquifer and the Coastal Subareas of the Seaside Groundwater Basin.  Exhibit 26-A focuses on four factors: rainfall, runoff, storage, and steelhead.  The report is limited to the water year that began October 1, 2007 and ended September 30, 2008 (WY 2008).  The rainfall and streamflow values are based on measurements recorded in the upper Carmel River Basin at San Clemente Dam.  This site was selected because of its location above storage facilities and the availability of long-term rainfall and runoff records.


Water Supply Status:  As shown, rainfall during WY 2008 totaled 19.6 inches, which is 92% of the long-term average.  Runoff during WY 2008 totaled 49,020 acre-feet (AF), which is 71% of average.  Usable storage, which includes surface and groundwater, was 25,690 AF or 91% of average at the end of September.  This storage equates to 68% of system capacity.  In addition, 412 adult steelhead were counted in the fish ladder at San Clemente Dam and approximately 83,380 juvenile steelhead were rescued from drying reaches of the Carmel River mainstem by District staff in WY 2008. 


Production Compliance:  Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, California American Water (CAW) is allowed to produce 11,285 AF of water from Carmel River sources in WY 2008.  Under a separate Memorandum of Understanding (MOU) with the National Marine Fisheries Service and the California Department of Fish and Game, this amount is reduced each year by the amount of water that is actually recovered from the Seaside Basin as part of the  Phase 1 Aquifer Storage and Recovery (ASR) Project and delivered to CAW’s customers during the low-flow period.  For example, in WY 2008, CAW recovered 60 AF of stored ASR water from the Seaside Basin during the July through September period for customer service.  As a result, CAW’s annual production limit under Order 95-10 and the NMFS/CDFG MOU in WY 2008 was 11,225 AF.    


Under the Seaside Basin Decision, CAW is allowed to produce 3,504 AF of water from the Coastal Subareas of the Seaside Groundwater Basin in WY 2008.  Altogether, CAW was allowed to produce 14,729 AF from Carmel River and Seaside Coastal sources for customers in its main system.  For WY 2008, CAW diverted 13,929 AF from the Carmel River and Seaside basins for customer use under its Order 95-10 rights.  This water production is 800 AF or approximately 5.4% less than the target system production specified for customers in the main system in WY 2008. 


A monthly breakdown of CAW’s production from the Carmel River and the Coastal Subareas of the Seaside Groundwater Basin for WY 2008 is included as Exhibit 26-B. CAW’s production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin.  These diversions are authorized under a water right that is jointly held by CAW and the District and are separate from the rights that were recognized for CAW in Order 95-10.  During WY 2008, CAW diverted 60 AF that was provided to the District for injection into the Coastal Subareas of the Seaside Groundwater Basin.
