Sparkill Creek is long and drains of watershed. It begins from runoff from Clausland Mountain in Orangetown, New York. Small tributaries feed the creek as it flows through the hamlets of Blauvelt, Orangeburg, and Tappan, New York, the borough of Northvale, New Jersey, the hamlets of Palisades and Sparkill, and finally the village of Piermont, New York before emptying into the Hudson River at Piermont Marsh.
