Manor Kill

Manor Kill is a river in Schoharie County in the state of New York. It begins northeast of Manorkill and flows westward before flowing into the Schoharie Reservoir southeast of Gilboa, New York. Manor Kill Falls is located on the creek where it passes under Prattsville Road (County Route 39). Since it drains into the Schoharie Reservoir, it is part of the New York City water supply system.

Hydrology
Manor Kill's watershed receives an average 36.8 in of precipitation annually. Most of it is concentrated in seasonal events such as summer thunderstorms, remnants of hurricanes later in the year or rain-on-snow events in springtime. This pattern of precipitation, combined with the Manor Kill watershed's slopes and low drainage density, results in flashiness, as the stream and its tributaries rise and fall quickly in response to storm events. The forests that cover much of the watershed tend to mitigate this somewhat.

The United States Geological Survey (USGS) maintains one stream gauge along Manor Kill. The station, in service since July 1986, is located 1.2 mi upstream from the mouth, .5 mi east of West Conesville, had a maximum discharge of 6590 cuft per second on August 28, 2011, as Hurricane Irene passed through the area. It had a minimum discharge of 1 cuft per second on August 28–31, 1993, September 1–2, 1993 and September 6–8, 1995.

History
The village of Conesville was previously known as "Stone Bridge" because of the great arched stone bridge that stood where the present bridge crosses the Bearkill. This bridge was washed away in a flood of 1874.
