Exhibit 27-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of December 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 27-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 0.72 inches, which is 25% of the long-term average. Runoff during WY 2008 to date has totaled 517 acre-feet (AF), which is 28% of average. Usable storage, which includes surface and groundwater, was 24,950 AF or 91% of average at the end of November. This storage equates to 67% of system capacity. In addition, no 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 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 2,286 AF from the Carmel River and Seaside basins for customer
use. This water production is 108 AF
or approximately 4.5% less than the target system production specified
for WY 2008 to date. A monthly breakdown
