Saw Kill tributary is located in Ulster County. 19.7 miles (31.7 km) long, it rises in Forest Preserve lands on the lower slopes of Indian Head Mountain and, after flowing through the town of Woodstock, empties into the Esopus just above Saugerties; just north of Route 209 and just downstream of Ulster Town Hall. The Saw Kill is one of the major tributaries to the Esopus. There is a sedimentary delta halfway across the Esopus Creek channel in this area, which indicates high sediment loads in the Saw Kill.
