Exhibit 20-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 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 20-A focuses on four factors: rainfall, runoff, storage, and steelhead. The report is limited to the water year that began October 1, 2008 and ended 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 totaled 18.14 inches, which is 85% of the long-term average. Runoff during WY 2009 totaled 47,500 acre-feet (AF), which is 69% of average. Usable storage, which includes surface and groundwater, was 27,180 AF or 97% of average at the end of WY 2009. This storage equates to 77% of system capacity. In addition, 95 adult steelhead were counted in the fish ladder at San Clemente Dam and 13,477 juvenile steelhead were rescued from drying reaches of the Carmel River mainstem by District staff in WY 2009.

Production Compliance: Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, California American Water (Cal-Am) was allowed to produce 11,285 AF of water from the Carmel River in WY 2009. In addition, under the Seaside Basin Decision, Cal-Am was 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, Cal-Am diverted 13,425 AF from the Carmel River and Seaside basins for customer use. This water production is 1,322 AF or approximately 9.0% less than the target specified for Cal-Am’s production from the MPWRS for WY 2009. A monthly breakdown of Cal-Am’s production from the Carmel River and the Seaside Groundwater Basin Subareas for WY 2009 is included as Exhibit 20-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 into the Seaside Groundwater Basin, based on the District’s meter readings at the Phase 1 ASR site, and recovered 182 AF for customer use.
