EXHIBIT 10-B
Quarterly Water Supply Strategy and
Budget Report
California-American Water, Water
Distribution System: October – December 2006
September

1. Management
Objectives
The
District desires to maximize the long-term production potential and protect the
environmental quality of the Carmel River and Seaside
Groundwater Basins. In addition, the District desires to maximize
the amount of water that can be diverted from the Carmel
River Basin and injected into the Seaside Groundwater
Basin while complying with the
instream flow requirements recommended by the NMFS to protect the Carmel River
steelhead population. To accomplish
these goals, a water supply strategy and budget for production within the
Cal-Am WDS is reviewed quarterly to determine the optimal strategy for
operations, given the current hydrologic and system conditions.
2. Quarterly
Water Supply Strategy: October - December 2006
On
September 6, 2006, staff from the District, Cal-Am, NMFS, and CDFG discussed
the proposed water supply strategy and related topics for the remainder of
September 2006 and the October-December 2006 period. Currently, flow in the Carmel River
is regulated and maintained by releases from Los Padres Reservoir. Los Padres Reservoir is at 73% capacity
(1,071 AF) and Carmel River flow at the District gaging station at the Don Juan Bridge in Garland
Park is approximately 11
cfs.
Carmel River
Basin Given these conditions,
it was agreed that Cal-Am would divert no surface water from its San Clemente
Reservoir and would divert no more than 31 AF per month from its Russell Wells
Nos. 2 and 4 in the Upper
Carmel Valley. To meet customer demand, Cal-Am would
operate its wells in the Lower
Carmel Valley
in a downstream-to-upstream sequence, as needed.
Seaside Groundwater
Basin It was agreed that Cal-Am would maximize
production from the Seaside
Basin in September and
would then progressively reduce its production during the October –December
2006 period. These levels of production
will help protect aquatic habitat in the Carmel
River Basin and ensure that Cal-Am
complies with the production limit set in the Seaside Groundwater
Basin adjudication
decision. Lastly, it was assumed that no water would be diverted from the Carmel River Basin
and injected into the Seaside
Coastal Basin
during the October – December 2006 period.
