  Notes:  
  1.  Water Year (WY) 2011 began October 1, 2010 and will end on September 30, 2011.  
  2.  Values in shaded areas represent current month.  
  3.  PROD = Production;  ANT = Anticipated; ACT = Actual.  
  4.  Actual WY 2011-to-date production of 8,615 AF includes 1,117 AF produced in the LCV in Dec 2010 - May 2011, and injected into the Seaside Basin.  
  5.  Anticipated reservoir activity values not available (N/A) for comparison with actual values.  
  6.  Usable reservoir storage volumes are based on capacities as follows:  
            San Clemente Reservoir (CAW, 2003):  137 AF (elev. 525') - 71 AF (min. pool @ elev. 515') = 66 AF  
            Los Padres Reservoir (CSUMB, 2008):  1,731 AF (flashboard out @ elev. 1038.90') - 105 AF (min. pool @ elev. 980') = 1,626 AF.  
                                                                           1,774 AF (flashboard in @ elev. 1039.78') - 105 AF (min. pool @ elev. 980') = 1,669 AF.  
  7.  Flashboard removed from Los Padres Dam notch on 9/20/10.
