During cold weather, ice effects on stage, groundwater levels, precipitation and water quality parameters at some stream-gaging stations and wells are likely. Data values reported on these pages may be significantly higher or lower than actual values. 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 or wells.
