Heavy rainfall (1.5 to 2.5 inches) and snowmelt led to the formation of a significant ice jam on the East Branch of the Ausable River at Au Sable Forks, NY during the late morning to early afternoon hours of 18 February, 2022. The jam moved downstream from the upper portions of the watershed in the Town of Jay, first creating high water near the juncture of US Route 9N and Stickney Bridge Road. The jam subsequently shifted downstream, lodging near the confluence of the East and West Branches of the Ausable River at Au Sable Forks. As a result, significant water was impounded behind the jam, severely flooding portions of the town, specifically on the Clinton County side of the river in what is called the Jersey section in the vicinity of Broad Street and Intervale Avenue. Flooding was also observed at the local Tops Supermarket and nearby Riverside Park. The river forecast gage on the East Branch of the Ausable River at Au Sable Forks (ASFN6) crested at 15.19 feet, its third highest crest on record. The jam held in place for approximately 2 to 3 hours before moving downstream, easing the flooding in town. Thereafter, it lodged shortly for a second time just upstream of the other Au Sable Forks gage (AUSN6) where flooding was noted along portions of Route 9N and some property on the south bank owned by Northline Utilities LLC. After a short time, the jam moved further downstream, finally lodging in the vicinity of the Lower Road Bridge near the high school in Clintonville, NY. Subsequent flooding of Dugway and Cassidy Roads on the south bank occurred before water carved a path through the jam and high water concerns eased by mid-afternoon. Post-event coordination with Clinton and Essex County Emergency Management revealed 35 homes and 1 town owned property damaged. Of those, 7 were deemed to have received critical damage, with 2 buildings and 4 apartments condemned.
