Exhibit 23-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of May 1, 2012. 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 is for Water Year (WY) 2012 and focuses on four factors: rainfall, runoff, storage, and steelhead. The rainfall and streamflow values are based on measurements in the upper Carmel River Basin at San Clemente Dam.

Water Supply Status: As shown, rainfall during April 2012 totaled 2.41 inches and brings the cumulative rainfall total for WY 2012 to 13.83 inches, which is 67% of the long-term average through April. Estimated unimpaired runoff during April 2012 totaled 5,469 acre-feet (AF) and brings the cumulative runoff total for WY 2012 to 16,703 AF, which is 27% of the long-term average through April. Usable storage, which includes surface and groundwater, was 30,910 AF, or 96% of the long-term average through April. This storage equates to 82% of system capacity. In addition, 470 adult steelhead were counted in the fish ladder at San Clemente Dam for WY 2012 through April.

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 Basin in WY 2012. In December 2011, the Seaside Watermaster determined that 32 AF of Cal-Am’s native groundwater allocation was not produced by Cal-Am in WY 2011. This amount 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 Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for ASR recovery or Sand City Desalination). For WY 2012 through April, Cal-Am has produced 6,244 AF from the Carmel River, Seaside Basins, Sand City Desalination, and ASR recovery, for customer use. This water production is 214 AF or 3.3% less than the target specified for Cal-Am’s production from the MPWRS for WY 2012 through April. A breakdown of Cal-Am’s production for WY 2012 through April 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” Seaside Basin production is reduced for injected water recovery. For WY 2012 through April, 132 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 1,117 AF have been recovered for customer use. Exhibit 23-C shows production breakdown from all sources for all uses.
