During cold weather, ice effects on stage and discharge determinations
at some stream-gaging stations are likely. Data values reported on
these pages may be significantly higher or lower than actual
streamflow. Adjustment of data for ice effects can only be done after
detailed analysis. Users are encouraged to contact this office for more
information on specific stream-gaging stations.
