Exhibit 22-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2013.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 22-A is for Water Year (WY) 2013 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 September 2013 totaled 0.13 inches and brings the cumulative rainfall total for WY 2013 to 14.60 inches, which is 69% of the long-term average through September.Estimated unimpaired runoff during September 2013 totaled 0 acre-feet (AF) and brings the cumulative runoff total for WY 2013 to 27,303 AF, which is 40% of the long-term average through September.Usable storage, which includes surface and groundwater, was 25,970 AF, or 92% of the long-term average through September.This storage equates to 69% of system capacity.In addition, 249 adult steelhead were counted in the fish ladder at San Clemente Dam and 42,805 Juvenile fish were rescued through September.


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 10,187 AF of water from the Carmel River in WY 2013.In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,887 AF (2,669 AF of native water and 219 AF of pre-permanent ASR injected water) of water from the Coastal Subareas and 147 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2013. Altogether, Cal-Am is currently allowed to produce 13,221 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 2013 through September, Cal-Am has produced 11,622 AF from the Carmel River, Seaside Basin, Sand City Desalination, and ASR recovery, for customer use.This water production is 1,381 AF or 10.6% less than the target specified for Cal-Amís production from the MPWRS for WY 2013 through September. A breakdown of Cal-Amís production for WY 2013 through September is included as Exhibit 22-B.Cal-Amís production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin; Cal-Amís ďnativeĒ Seaside Basin production is reduced for injected water recovery. For WY 2013 through September, 295 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 644 AF have been recovered for customer use.Exhibit 22-C shows production breakdown from all sources for all uses.Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
