Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of November 1, 2011. 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 focuses on four factors: rainfall, runoff, storage, and steelhead. The report is limited to the water year that began October 1, 2011 and ended September 30, 2012 (WY 2012). The rainfall and streamflow values are based on measurements 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 October 2011 totaled 1.71 inches and brings the cumulative rainfall total for WY 2012 to 1.71 inches, which is 223% of the long-term average through October of 0.77 inches. Estimated unimpaired runoff during October 2011 totaled 891 acre-feet (AF) and brings the cumulative runoff total for WY 2012 to 891 AF, which is 221% of the long-term average through October of 403 AF. Usable storage, which includes surface and groundwater, was 29,390 AF, or 108% of the long-term average through October of 27,290 AF. This storage equates to 78% of system capacity. In addition, 0 adult steelhead were counted in the fish ladder at San Clemente Dam for WY 2012 through October.

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 Groundwater Basin in WY 2012. Altogether, Cal-Am is currently allowed to produce 12,977 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 its Laguna Seca subsystems, i.e., Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for ASR recovery or Sand City desalination plant production). For WY 2012 through October, Cal-Am has produced 1,026 AF from the Carmel River, Seaside Basins, Sand City Desalination, and ASR recovery, for customer use. This water production is 151 AF or 12.9% less than the target specified for Cal-Am’s production from the MPWRS for WY 2012 through October. A monthly breakdown of Cal-Am’s production from the Carmel River and the Seaside Groundwater Basin Subareas for WY 2012 through October 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” production from the Seaside Basin is reduced for the recovery of injected water. For WY 2012 through October, 0 AF of groundwater have been diverted from the Carmel River aquifer for injection into the Seaside Groundwater Basin; 373 AF have been recovered for customer use.
