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
