Chelsea is a hamlet of the Town of Wappinger in Dutchess County, New York, United States. It is located on the Hudson River in the southwestern corner of the town. It takes the ZIP Code 12512 and is in the 845 telephone area code, and has its own fire district.
Chelsea is a small community, primarily residential. A marina is located on the river. Just north of the hamlet is a large pumping station used by the New York City water supply system during droughts to take water directly from the river,[1] since the hamlet is located around the point where the river water becomes fresh enough to drink even in the dryest of times.[2]
New York City has had a long- standing application for a permanent permit to operate the Chelsea plant during state-declared drought emergencies by pumping 100 million US gallons (380,000 m3) of water a day from the Hudson River.
