Exhibit 22-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of November 1, 2006.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 Ground Water 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 on 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 has totaled 0.16 inches, which is 22% of the long-term average.Runoff during WY 2007 has totaled 500 acre-feet (AF), which is 137% of average.Usable storage, which includes surface and ground water, was 28,460 AF or 105% of average at the end of October.This storage equates to 76% of system capacity.In addition, zero adult steelhead have been counted in the fish ladder at San Clemente Dam and zero juvenile steelhead have been rescued from drying reaches of the Carmel River mainstem by District staff in Water Year 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 current District water supply budgets, Cal-Am is projected to produce a maximum of 1,200 AF of water from the coastal subareas of the Seaside Groundwater Basin during the first quarter of Water Year 2007.Cal-Amís projected production from the coastal subareas of the Seaside Basin is consistent with the 3,504 AF limit set for Cal-Am in the Seaside Basin adjudication decision for Calendar Year (CY) 2006.†††

 

For WY 2007 to date, Cal-Am has diverted 1,266 acre-feet from the Carmel River and Seaside basins for customer use.This water production is 57 AF or approximately 4.3% less than the target system production specified for WY 2007.A monthly breakdown of Cal-Amís production from the Carmel River and the coastal subareas of the Seaside Ground Water Basin for WY 2007 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 zero AF of water into the Seaside Groundwater Basin.
