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

Additional comments:
The period of record for the Zumbro River at Kellogg, MN is not sufficient
to cover the entire period of record for the constituent data.
Flow at the sample site was estimated using a linear regression with the flow of the
Root River at Houston, MN. (05385000) and a land / area conversion factor (see
flow conversion above).  The conversion equation used was: Zumbro River at 
Kellogg (05374900) = 0.7611 x Root River at Houston (05385000)
R2 = 0.7207
