  Text Box: Notes: 1. The budget reflects "critically-dry" inflow conditions and assumes that the monthly inflows at the San Clemente Dam site during the January-March 2008 period will approximate the 87.5% exceedence frequency flows, based on the 1902-2007 simulated period of record. 2. The annual budget period corresponds to the Water Year, which begins on October 1 and ends on September 30 of the following Calendar Year. 3. Total monthly production for "Customer Service" in CAW's main system was calculated by multiplying total annual production (14,789 AF) times the average percentage of annual production for January, February, and March (6.36%, 5.86%, and 6.76%, respectively). The annual production total was based on the assumption that production from the Coastal Subareas of the Seaside Groundwater Basin would not exceed 3,504 AF and production from Carmel River sources would not exceed 11,285 AF in WY 2008. The average production percentages were based on monthly production data for customer service from 1986 to 2006. 4. Anticipated production for "Seaside Injection" is based on an average diversion rate of approximately 1,000 gallons per minute (gpm) or 4.4 AF per day from CAW's sources in the Carmel River Basin. "Total" monthly CAW "use" includes water for customer service and water for injection into the Seaside Groundwater Basin. 5. No surface water diversions from San Clemente Reservoir are assumed for this period based on concerns regarding water quality (elevated turbidity) and lowered water levels required by the Division of Dam Safety as part of the San Clemente Reservoir Drawdown Project. 6. Because of the uncertainty associated with predicting rainfall and runoff for the January-March 2008 period, the projected production values may change. Specifically, if runoff amounts in the Carmel River are greater than expected under the assumed critically-dry conditions, then production from the Seaside Basin in January and February will be curtailed and production from sources in the Carmel River Basin will be increased to meet customer demand, consistent with SWRCB Order 98-04.
