  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 Seaside Coastal monthly production of 294 AF represents ASR recovery water from the 1,111 AF that were injected in WY 2010.
  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 on 9/20/10.
