Preliminary Acoustic Water Level Data (A1)
 
       Station   --   Unique seven character identifier for the station          
       D         --   A one character identifier for the data collection platform (DCP) at a
                      station                                                                        
       SE        --   A two character identifer for the data sensor                      
       Date Time --   Date and time the data were collected by the DCP           
       WL        --   Water level height                                                                                 
       Sigma     --   Standard deviation of 1 second samples used to compute the water level
          	      height                                                     
       O         --   Count of number of samples that fall outside a 3-sigma band about the mean                                                        
       F         --   A flag that when set to 1 indicates that the flat tolerance limit was exceeded                                                       
       R         --   A flag that when set to 1 indicates that the rate of change tolerance limit was
		      exceeded                                     
       T         --   A flag that when set to 1 indicates that the                       
                      temperature difference tolerance limit was exceeded                       
       L         --   A flag that when set to 1 indicates that either the maximum or minimum expected
		      water level height limit was exceeded
