  Notes:  
  1.  Water Year (WY) 2010 began on October 1, 2009 and will end on September 30, 2010.  
  2.  Values in shaded areas represent current month.  
  3.  PROD = Production;  ANT = Anticipated; ACT = Actual.  
  4.  Actual WY 2010-to-date production of 8,422 AF includes 1,111 AF produced in the LCV (Dec 2009 - May 2010), and injected into the Seaside Basin.
  5.  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.  
  6.  Flashboard removed from Los Padres Dam notch 10/23/09.
