ON STREAMFLOW -- During cold weather, stage and discharge values may be
affected by ice at some streamgages. Streamgages experiencing ice
conditions will have the discharge record temporarily disabled to
prevent the display of erroneous discharge values. Display of discharge
record will resume when it is determined that ice conditions are no
longer present. Adjustment of data affected by ice can only be done
after detailed analysis.
