Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of February 1, 2009. This system includes the surface water resources in the Carmel River Basin, the ground water 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 6.3 inches, which is 56% of the long-term average. Runoff during WY 2009 to date has totaled 3,210 acre-feet (AF), which is 16% of average. Usable storage, which includes surface and groundwater, was 26,670 AF or 88% of average at the end of October. This storage equates to 71% 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 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 January 2009, CAW has diverted 4,083 AF from the
Carmel River and Seaside basins for customer use. This water production is 330 AF or
approximately 7.5% less than the target specified for CAW’s production
from the MPWRS for WY 2009 to date. A
