Exhibit 28-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of May 1, 2003.  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 Ground Water 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, 2002 and will end on September 30, 2003 (WY 2003).  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 2003 through April totaled 23.1 inches, which is 112% of the long-term average.  Runoff during WY 2003 through April totaled 45,220 acre-feet, which is 72% of average.  Usable storage, which includes surface and ground water, was 32,720 acre-feet or 101% of average at the end of April 2003.  This storage equates to 87% of system capacity. 

 

In addition, 480 adult steelhead have been counted in the fish ladder at San Clemente Dam in WY 2003, which is 91% of the long-term average.  In addition, 108 juvenile steelhead have been rescued from drying reaches of the Carmel River mainstem by District staff during WY 2003. 

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, Cal-Am is allowed to produce no more than 11,285 acre-feet of water from the Carmel River in WY 2003.  In addition, under current District water supply budgets, Cal-Am is allowed to produce a maximum of 4,000 acre-feet of water from the Seaside Basin coastal subareas in WY 2003.  Combined, Cal-Am is limited to 15,285 acre-feet of production in WY 2003. 

 

For WY 2003 through April, Cal-Am has diverted 7,104 acre-feet from the Carmel River and Seaside basins for customer use.  This water production is 480 acre-feet or approximately 6.3% less than the target system production for WY 2003 to date.  A monthly breakdown of Cal-Am’s production from the Carmel River and Seaside Basin Coastal subareas for WY 2003 is included as Exhibit 28-B.  Cal-Am’s production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin.  During WY 2003 through April, the District has injected 119 acre-feet of water into the Seaside Ground Water Basin.
