Exhibit
18-A
shows the water supply status for the Monterey Peninsula Water Resources System
(MPWRS) as of October 1, 2003. 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 Ground Water Subareas. Exhibit
18-A focuses on four factors: rainfall, runoff, storage, and steelhead.
The
report is limited to the water year that began October 1, 2002 and ended
September 30, 2003 (WY 2003). 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 2003 totaled 24.3
inches, which is 114% of the long-term average. Runoff during WY 2003 totaled 56,020 acre-feet, which is
81% of average. Usable storage, which
includes surface and ground water, was 28,460 acre-feet or 102% of
average at the end of WY 2003. This
storage equates to 76% of system capacity.
In
addition, 483 adult steelhead were counted in the fish ladder at San
Clemente Dam in WY 2003, which is 91% of the long-term average. In addition, 55,287 juvenile steelhead
were rescued from drying reaches of the Carmel River mainstem and its
tributaries during WY 2003. Of this total, 39,553 juveniles were rescued
by District staff from the mainstem and 15,734 juveniles were rescued by
members of the Carmel River Steelhead Association (CRSA) from the mainstem and
tributaries in WY 2003.
Production
Compliance: Under State Water Resources Control Board
(SWRCB) Order No. WR 95-10, Cal-Am is allowed to produce no more than 11,285
acre-feet of water from the Carmel River in WY 2003. In addition, under current District water supply budgets, Cal-Am
is allowed to produce a maximum of 4,000 acre-feet of water from the Seaside Basin
coastal subareas in WY 2003. Combined,
Cal-Am is limited to 15,285 acre-feet of production in WY 2003.
For WY
2003, Cal-Am diverted 14,638 acre-feet from the Carmel River and Seaside basins
for customer use. This water production
is 647 acre-feet or approximately 4.2% less than the target system production
for WY 2003. A monthly breakdown of
Cal-Am’s production from the Carmel River and Seaside Basin Coastal subareas
for WY 2003 is included as Exhibit 18-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 2003, the District
injected 168 acre-feet of water into the Seaside Ground Water Basin.
