Exhibit 18-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 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 18-A focuses on four factors: rainfall, runoff, storage, and steelhead.
The report is limited to the water year that began October 1, 2002 and ended 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 totaled 24.3 inches, which is 114% of the long-term average.† Runoff during WY 2003 totaled 56,020 acre-feet, which is 81% of average.† Usable storage, which includes surface and ground water, was 28,460 acre-feet or 102% of average at the end of WY 2003.† This storage equates to 76% of system capacity.†
In addition, 483 adult steelhead were counted in the fish ladder at San Clemente Dam in WY 2003, which is 91% of the long-term average.† In addition, 55,287 juvenile steelhead were rescued from drying reaches of the Carmel River mainstem and its tributaries during WY 2003. Of this total, 39,553 juveniles were rescued by District staff from the mainstem and 15,734 juveniles were rescued by members of the Carmel River Steelhead Association (CRSA) from the mainstem and tributaries in 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, Cal-Am diverted 14,638 acre-feet from the Carmel River and Seaside basins for customer use.† This water production is 647 acre-feet or approximately 4.2% less than the target system production for WY 2003.† A monthly breakdown of Cal-Amís production from the Carmel River and Seaside Basin Coastal subareas for WY 2003 is included as Exhibit 18-B.† Cal-Amís production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin.† During WY 2003, the District injected 168 acre-feet of water into the Seaside Ground Water Basin.
