Exhibit 22-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of April 1, 2007.This system includes the surface water resources in the Carmel River Basin, the ground water resources in the Carmel Valley Alluvial Aquifer, and Seaside Coastal Groundwater Subareas. Exhibit 22-A focuses on four factors: rainfall, runoff, storage, and steelhead.The report is limited to the water year that began October 1, 2006 and will end September 30, 2007 (WY 2007).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 2007 to date has totaled 10.3 inches, which is 54% of the long-term average.Runoff during WY 2007 to date has totaled 9,850 acre-feet (AF), which is 18% of average.Usable storage, which includes surface and ground water, was 31,980 AF or 102% of average at the end of March.This storage equates to 85% of system capacity.In addition, 220 adult steelhead have been counted in the fish ladder at San Clemente Dam in WY 2007 to date.No juvenile steelhead have been rescued from drying reaches of the Carmel River mainstem by District staff in WY 2007.Similarly, no steelhead rescues have been made by Carmel River Steelhead Association (CRSA) volunteers in WY 2007 to date.

Production Compliance:Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, Cal-Am is allowed to produce no more than 11,285 AF of water from the Carmel River in WY 2007.In addition, under the current District water supply budget, Cal-Am is projected to produce up to 1,200 AF of water from the coastal subareas of the Seaside Groundwater Basin during the first six months of Water Year 2007.This limit is consistent with the allocation of 3,504 AF of extractions from the coastal subareas specified for Cal-Am in the Seaside adjudication for WY 2007.For WY 2007 to date, Cal-Am has diverted 6,014 AF from the Carmel River and Seaside basins for customer use.This water production is 148 AF or approximately 2.4% less than the target system production specified for WY 2007 to date.A monthly breakdown of Cal-Amís production from the Carmel River and the coastal subareas of the Seaside Groundwater Basin for WY 2007 to date is included as Exhibit 22-B.Cal-Amís production from the Carmel River Basin is reduced for diversions that were made for injection into the Seaside Basin.During WY 2007 to date, the District has injected 12 AF water into the coastal portion of the Seaside Groundwater Basin.
