[!] ICE EFFECTS ON STREAMFLOW -- During cold weather, ice effects on stage and discharge determinations at some streamgages are likely. Streamgages experiencing ice conditions will have the discharge record temporarily disabled to prevent the display of erroneous discharge values. The discharge record will resume when it is determined that ice conditions are no longer present. Adjustment of data for ice effects can only be done after detailed analysis.
