Lake Washington is the primary reservoir for the city of Newburgh, New York, United States. It is located just southwest of the city, lying partially within it and the neighboring towns of Newburgh and New Windsor. It holds approximately 1.5 billion US gallons (5,700,000 m3), an amount equivalent to the city's annual consumption.
Lake Washington was expanded and put into service as a reservoir in 1907, although it had been providing water to its predecessor, Monell's Pond, since 1852. The dam has been raised many times since then to increase capacity.
In 2016 the city briefly declared a water emergency and started using Browns Pond, its backup supply, when levels of perfluorooctane sulfonate (PFOS) near the federal Environmental Protection Agency guidelines of 200 parts per trillion (ppt) were found in the lake. It is not known yet where the PFOS came from; a pond on the Stewart Air Guard Base from which Silver Stream, one of Lake Washington's tributaries, rises, had levels of 5,900 ppt. If Brown's Pond runs out before the contamination can be remediated, the city would have to pay to draw from the Catskill Aqueduct, part of the New York City water supply system.
Resident Frank Masterson had long dreamed of a place where the disabled, senior citizens and military veterans could go to fish. After his death in 1973, his friends decided to honor his memory by establishing such a park, and it was opened the following year.
