News - updated January 2010

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.
