The following constituent values were removed from analysis as
possible outliers, or are below detection limits:
Date        Constituent        Concentration
02/09/1996  Total Phosphorus   3.260

Additional comments:
The period of record for flow at the Plum River at Savanna is not 
sufficient to cover the period of record for the constituent data.
Flow data previous to 10/1994 was estimated using a linear regression
with the Apple River at Hanover, IL (05419000).  
The conversion equation used was:
Discharge of Plum River at Savanna, IL = 1.088 x (flow of Apple River at Hanover, IL)
R2 = 0.7636

Loads for this site were estimated with LOADEST2 version 1.10
