Exhibit 25-A shows the
water supply status for the Monterey Peninsula Water Resources System (MPWRS)
as of July 1, 2009. This system includes
the surface water resources in the Carmel
River Basin, the groundwater resources
in the Carmel Valley Alluvial Aquifer and the Seaside Groundwater
Basin. Exhibit 25-A
focuses on four factors: rainfall, runoff, storage, and steelhead. The report is limited to the water year that
began October 1, 2008 and will end September 30, 2009 (WY 2009). 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 2009 to date has totaled 18.1 inches, which is
85% of the long-term average. Runoff
during WY 2009 to date has totaled 45,890 acre-feet (AF), which is 68%
of average. Usable storage, which
includes surface and groundwater, was 30,260 AF or 97% of average at the
end of June. This storage equates to 80%
of system capacity. In addition, 95 adult
steelhead were counted in the fish ladder at San Clemente Dam and 698 juvenile
steelhead have been rescued from drying reaches of the Carmel River
mainstem by District staff in WY 2009 to date.
Production Compliance: Under
State Water Resources Control Board (SWRCB) Order No. WR 95-10, California
American Water (Cal-Am) is allowed to produce 11,285 AF of water from the Carmel River
in WY 2009. In addition, under the
Seaside Basin Decision, Cal-Am is allowed to produce 3,191 AF of water from the
Coastal Subareas and 271 AF from the Laguna Seca Subarea of the Seaside Groundwater Basin
in WY 2009, as modified by the Seaside Basin Watermaster in May 2009. Altogether, Cal-Am is currently
allowed to produce 14,476 AF from Carmel
River and Seaside Coastal sources for
customers in its main Monterey
system and 271 AF from the Laguna Seca Subarea for customers in its Laguna Seca
subsystems, i.e., Ryan Ranch, Hidden Hills, and Bishop Systems. For WY 2009 through June 2009, Cal-Am has
diverted 9,261 AF from the Carmel River and Seaside
basins for customer use. This water
production is 849 AF or approximately 8.4% less than the target
specified for Cal-Am’s production from the MPWRS for WY 2009 to date. A monthly breakdown of Cal-Am’s production
from the Carmel River and the Seaside Groundwater Basin
Subareas for WY 2009 to date is included as Exhibit 25-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 2009, the District injected 182 AF of water from the Carmel River Basin
into the Seaside Groundwater Basin,
based on the District’s meter readings at the Phase 1 ASR site.
