Due to a gage relocation, the flood stage level has recently changed(9/4/2008). The relocated gage is now on the left bank (upstream side) near the Rising Sun Bridge. The gage was previously 1/2 mile downstream below Mill Dam. Historical data associated with the new gage, such as crests and low water levels, will be listed as they occur. Here are the top four crests associated with the old location...15.49 ft on 06/23/1972...15.43 ft on 09/17/1999...13.89 ft on 08/19/1955...13.83 ft on 09/13/1971. Here are the top four low water records associated with the old location...2.31 ft on 09/13/1995...2.38 ft on 08/19/1963...2.49 ft on 10/31/1963...2.57 ft on 08/31/1965. During winter months, cold and ice may result in inaccurate real-time stream stage and streamflow data. Adjustments or deletions of this data can only be done after detailed analysis.
