Exhibit 34-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of April 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 34-A focuses on four factors: rainfall, runoff, storage, and steelhead. The report is limited to the water year that began October 1, 2007 and will end 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 to date has totaled 19.4 inches, which is 102% of the long-term average. Runoff during WY 2008 to date has totaled 43,070 acre-feet (AF), which is 80% of average. Usable storage, which includes surface and groundwater, was 30,920 AF or 95% of average at the end of March. This storage equates to 82% of system capacity. In addition, 403 adult steelhead have been counted in the fish ladder at San Clemente Dam and no juvenile steelhead have been rescued from drying reaches of the Carmel River mainstem by District staff in WY 2008 to date.
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
the Carmel River in WY 2008. In
addition, under the Seaside Basin Decision, CAW is allowed to produce 3,504 AF
of water from the Coastal Subareas and 345 AF from the Laguna Seca Subarea of
the Seaside Groundwater Basin in WY 2008.
Altogether, CAW is allowed to produce 14,789 AF from Carmel River and
Seaside Coastal sources for customers in its main system. For WY 2008 to date, CAW has diverted 5,836
AF from the Carmel River and Seaside basins for customer use. This water production is 326 AF or
approximately 5.3% less than the target system production specified for
WY 2008 to date. A monthly breakdown of
CAW’s production from the
