East Kill, a 16-mile-long (26 km)[2] tributary of Schoharie Creek, flows across the town of Jewett, New York, United States, from its source on Stoppel Point.

The highest point in the East Kill watershed is 3,948 feet (1,203 m) at the summit of Black Dome Mountain in southeast Jewett.

Fish and Wildlife Service has identified 168 separate wetlands within the East Kill watershed, totaling 311 acres (126 ha), including all open water.

When settlers first arrived in the East Kill Valley, they frequently encountered bears, wolves, and other dangerous wildlife.

When the majority of the forests were cleared, dairy farms became the dominant economic revenue in the East Kill valley.

[5] Lodgement till, which is a very dense, clay-rich, and reddish brown deposit, is very frequent in the East Kill and upper Schoharie Creek watersheds.

The extreme density is distinguished from the looser assemblage of mixed sediment that comprises melt-out till found in moraines and along mountain sides.

The presence of bedrock banks in the East Kill can represent natural limits to changes in the stream channel system.

[5] The East Kill's watershed receives an average 44 inches (1,100 mm) of precipitation annually, making it one of the wettest areas of the Catskills.

The station is located on Mill Hollow Road, 1.3 miles (2.1 km) northeast of Jewett Center, had a maximum discharge of 28,400 cubic feet (800 m3) per second on August 28, 2011, as Hurricane Irene passed through the area, and a minimum discharge of 0.84 cubic feet (0.024 m3) per second on August 13, 1997.

[7] DEC rates the water quality of the stream as Class C, suitable for fishing and non-contact human recreation.

From there they go to Ashokan Reservoir, which supplies 10 percent of the city's water, and then, via the Catskill Aqueduct, to customers, without requiring filtration.

[7] In 2006, a combined effort of the Greene County Soil and Water Conservation District and the DEP resulted in a management plan for East Kill.

Then in 2011, a project was performed to repair aggradation upstream of the Vista Ridge bridge, and fix where the creek changed its course closer towards Colgate Lake road.

The project protected the road, and planted native trees and shrubs to reduce erosion and prevent future flood damage.
