Exhibit 30-A shows the
water supply status for the Monterey Peninsula Water Resources System (MPWRS)
as of April 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 30-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 17.2 inches, which is
91% of the long-term average. Runoff
during WY 2009 to date has totaled 37,630 acre-feet (AF), which is 70%
of average. Usable storage, which
includes surface and groundwater, was 30,600 AF or 95% of average at the
end of March. This storage equates to 82%
of system capacity. In addition, 84 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 2009 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 2009, unless modified by the SWRCB.
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 2009, unless modified by the Seaside Basin Watermaster. Altogether, CAW is currently allowed
to produce 14,789 AF from Carmel River and Seaside Coastal sources for customers in its
main Monterey
system and 345 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 March 2009, CAW has
diverted 5,659 AF from the Carmel River and Seaside
basins for customer use. This water
production is 644 AF or approximately 10.2% less than the target
specified for CAW’s production from the MPWRS for WY 2009 to date. A monthly breakdown of CAW’s production from
the Carmel River and the Seaside Groundwater Basin
Subareas for WY 2009 to date is included as Exhibit
30-B. CAW’s production from the Carmel
River Basin is reduced for diversions
that are made for injection into the Seaside
Basin. During WY 2009 to date, the District has
injected 206 AF of water from the Carmel River Basin
into the Seaside Groundwater Basin,
based on CAW meter readings at the Luzern site.
