When the "main event" occured with the 3.43" of rain in a 15-hour period from the remnants of TS Nicole, river, stream & urban flooding occured in many areas of Northern New York. In Lewis County near Lowville. several roads were closed due to at least 6 inches of water over Bealuk Road near Lowville as the Black River completely covered a large field in that area.Moving to Oswego County, in the village of Pulaski the swollen Salmon River threatened a building when the ground alongside the shores of the river began to give way. In St Lawrence County the Regis River was a raging torrent at Allens Falls near Parishville... In Potsdam, NY we had severe urban flooding in several backyards in one block of houses bordered by Beal Street, Waverly Street, Pleasant Street& parts of an adjacent neighborhood on Broad Street.. near the Potsdam business district. In this same neighborhod block many residents reported massive basement flooding when these people reported 3 to 5 feet of water in their cellars. It is not known whether they had flood insurance or not. Just south of Potsdam on Outer Main Street, the Parkhurst brook was way over its banks completely covering a cow pasture located about 1 mile south of the State University College @ Potsdam. classes at Potsdam State were unaffected by the rains and flooding.
