(09/08/2011) -- Remnants of Tropical Storm Lee cause record flooding in the Susquehanna River Basin

Remnants from Tropical Storm Lee caused record breaking flooding in the Susquehanna River basin and moderate flooding in Central New York. In some areas, as much as nine in. of rain fell between Wednesday afternoon and Thursday. Major flooding occurred at most sites in the Susquehanna Basin. Moderate to minor flooding was experienced in the Finger Lakes region. Several gages have exceeded previously recorded peaks.

The USGS streamgages Mohawk River at Little Falls and the East Branch Delaware River at Downsville, NY were among the sites that rose above flood stage on Sept 7-8, 2011, but major flooding is being recorded in the Susquehanna River basin. Several USGS streamgages along the Susquehanna River have crested about 10 feet above flood stage and recorded new period-of-record maximums during this event.

Provisional Flood Peaks:
A table of provisional flood peaks and flood frequency estimates has been prepared in cooperation with the New York State Department of Transportation. *Check back often for updates!*
