Exhibit 23-A shows the
water supply status for the Monterey Peninsula Water Resources System (MPWRS)
as of March 1, 2012. 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 23-B
is for Water Year (WY) 2012 and focuses
on four factors: rainfall, runoff, storage, and steelhead. The rainfall and streamflow
values are based on measurements in the upper Carmel River Basin
at San Clemente Dam.
Water Supply Status: As
shown, rainfall during February 2012
totaled 0.9 inches
and brings the cumulative rainfall
total for WY 2012 to 7.48 inches, which is 48% of the long-term average through February. Estimated
unimpaired runoff during February 2012
totaled 1,637 acre-feet (AF) and brings the cumulative runoff total for
WY 2012 to 7,394 AF, which is 20% of
the long-term average through February. Usable storage, which includes surface and
groundwater, was 30,290 AF,
or 97% of the long-term average through
February. This storage equates to 80% of system capacity. In
addition, 33 adult steelhead were counted
in the fish ladder at San Clemente Dam for WY 2012 through February.
Production Compliance: Under
State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2009-0060,
California American Water (Cal-Am) is allowed to produce no more than 10,308 AF
of water from the Carmel
River in WY 2012. In addition, under the Seaside Basin
Decision, Cal-Am is allowed to produce 2,669 AF of water from the Coastal
Subareas and 147 AF from the Laguna Seca Subarea of the Seaside Basin
in WY 2012. In December 2011, the
Seaside Watermaster determined that 32 AF of Cal-Am’s
native groundwater allocation was not produced by Cal-Am in WY 2011. This amount
was added to Cal-Am’s WY 2012 allotment (2,669 AF +
32 AF = 2,701 AF). Altogether, Cal-Am is
currently allowed to produce 13,009 AF from Carmel
River and Seaside Coastal sources for
customers in its main Monterey
system and 147 AF from the Laguna Seca Subarea for customers in Ryan Ranch,
Hidden Hills, and Bishop Systems (not adjusted for ASR recovery or Sand City Desalination). For WY 2012 through February, Cal-Am has produced 4,539
AF from the Carmel River, Seaside
Basins, Sand City
Desalination, and ASR recovery, for customer use. This water production is 32 AF or 0.7%
less than the target specified for Cal-Am’s production from the
MPWRS for WY 2012 through February. A breakdown of Cal-Am’s
production for WY 2012 through February
is included as Exhibit 23-B. Cal-Am’s production
from the Carmel River
Basin is reduced for diversions that are made for injection
into the Seaside Basin;
Cal-Am’s “native” Seaside Basin
production is reduced for injected water recovery. For WY 2012 through February, 0 AF of Carmel River Basin groundwater
have been diverted for Seaside Basin injection; 1,117 AF have been recovered for customer use. Exhibit 23-C
shows production breakdown from all
sources for all uses.
