Exhibit 21-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of December 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 21-B focuses on four factors: rainfall, runoff, storage, and steelhead. The report is limited to the water year that began October 1, 2011 and ends 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 November 2011 totaled 1.59 inches and brings the cumulative rainfall total for WY 2012 to 3.30 inches, which is 115% of the long-term average through November of 2.87 inches. Estimated unimpaired runoff during November 2011 totaled 1,190 acre-feet (AF) and brings the cumulative runoff total for WY 2012 to 2,081 AF, which is 112% of the long-term average through November of 1,863 AF. Usable storage, which includes surface and groundwater, was 29,870 AF, or 109% of the long-term average through November of 27,410 AF. This storage equates to 79% of system capacity. In addition, 0 adult steelhead were counted in the fish ladder at San Clemente Dam for WY 2012 through November.

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. In December 2011, the Seaside Watermaster determined that 32 AF of native groundwater was not produced by Cal-Am in WY 2011. This ammount 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 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 November, Cal-Am has produced 1,900 AF from the Carmel River, Seaside Basins, Sand City Desalination, and ASR recovery, for customer use. This water production is 229 AF or 10.9% less than the target specified for Cal-Am’s production from the MPWRS for WY 2012 through November. A monthly breakdown of Cal-Am’s production from the Carmel River and the Seaside Groundwater Basin Subareas for WY 2012 through November is included as Exhibit 21-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 November, 0 AF of groundwater have been diverted from the Carmel River aquifer for injection into the Seaside Groundwater Basin; 728 AF have been recovered for customer use.
