Exhibit 28-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2007.  This system includes the surface water resources in the Carmel River Basin, the ground water resources in the Carmel Valley Alluvial Aquifer, and Seaside Coastal Groundwater Subareas.  Exhibit 28-A focuses on four factors: rainfall, runoff, storage, and steelhead.  The report is limited to the water year that began October 1, 2006 and ended on September 30, 2007 (WY 2007).  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 2007 totaled 11.8 inches, which is 55% of the long-term average.  Runoff during WY 2007 totaled 12,540 acre-feet (AF), which is 18% of average.  Usable storage, which includes surface and ground water, was 25,450 AF or 90% of average at the end of September.  This storage equates to 68% of system capacity.  In addition, 222 adult steelhead were counted in the fish ladder at San Clemente Dam in WY 2007 through April 3, 2007.  Approximately 12,030 juvenile steelhead were rescued from drying reaches of the Carmel River mainstem by District staff in WY 2007. 


Production Compliance:  Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, California American Water (CAW) is allowed to produce no more than 11,285 AF of water from the Carmel River in WY 2007.  Similarly, under the Seaside Basin Adjudication Decision, CAW is allowed to produce no more than 3,504 AF of water from the Coastal Subareas of the Seaside Groundwater Basin in WY 2007.  For WY 2007, CAW diverted 14,068 AF from the Carmel River System and Coastal Subareas of the Seaside Basin for customer use.  This water production is 721 AF or approximately 4.9% less than the target system production specified for WY 2007.  A monthly breakdown of CAW’s production from the Carmel River and the Coastal Subareas of the Seaside Groundwater Basin for WY 2007 is included as Exhibit 28-B. CAW’s production from the Carmel River Basin is reduced for diversions that were made for injection into the Seaside Basin.  During WY 2007, the District injected 12 AF water into the coastal portion of the Seaside Groundwater Basin.
