Lake Washington is the largest lake in Brevard County, Florida at 4,362 acres (17.65 km2). The lake may have been named for the U.S. Deputy Surveyor Colonel Henry Washington, after he surveyed the area in 1844.
It is the 41st largest lake in the state of Florida. It is approximately 4 by 1 mile (6.4 by 1.6 km) and 10 to 15 feet (3.0 to 4.6 m) deep.


Located adjacent to the City of Melbourne, it is the single most important source of fresh water for the city and the surrounding areas. It furnishes two-thirds of the water to Melbourne’s 150,000 customers.[3]

The John A. Buckley Surface Water Treatment Plant is located nearby. It is owned by the City of Melbourne and furnishes it, and other cities, with potable water.

It is one of the lakes that make up the St. Johns River system. Further downstream is the neighboring Lake Winder.
