  Text Box: Notes: 1. The annual budget period corresponds to the Water Year, which begins on October 1 and ends on September 30 of the following Calendar Year. 2. Total monthly production for "Customer Service" in CAW's Highway 68 systems was calculated by multiplying total annual production (345 AF) times the average percentage of annual production for January, February, and March (4.64%, 4.21%, and 5.61%, respectively). The annual production total was based on the assumption that production from the Laguna Seca Subarea of the Seaside Groundwater Basin would not exceed 345 AF. The average production percentages were based on monthly data for customer service from WY 2000 to 2007. The 345 AF annual production limit is specified in the Seaside Basin Adjudication Decision. 3. It should be noted that, based on recent historical use, actual monthly use will likely exceed the proposed monthly production target. For example, in the January through March 2009 period, CAW produced 24, 25, and 39 AF to meet customer demand in its Highway 68 systems. In this context, the production targets represent the maximum monthly production that should occur so that CAW remains within its Standard Production Allocation for the Laguna Seca Subarea specified in the Seaside Decision. However, because the Seaside Decision allows CAW to combine its production in the Coastal Subareas with its production in the Laguna Seca Subarea in determining compliance, CAW can use production savings in the Coastal Subareas to offset overproduction in the Laguna Seca Subarea. 4. "Other" production sources refer to supplies transferred to Highway 68 customers from CAW's Carmel River sources or water rights acquired from other producers in the Seaside Basin to produce additional water.
