Flow conversion: 
     Occasional missing flow values (fewer than 10 total) were 
     substituted with values from the USGS gaging station at Clinton, IA
     (05420500).  A linear regression equation was calculated to substitute
     flows for these two sites.  The equation used follows:
     flow at Lock and Dam #12 = 1.0109 x Flow at Clinton Iowa (05420500)
     R2 = 0.9939

The following constituent values were removed from analysis as
possible outliers, or are below detection limits: none
