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.[2]

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. The water main is 36 inches (910 mm) in diameter[4].

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


Exit 183 off Interstate 95 provides access to the lake.

At the dead end of Lake Washington Road is Lake Washington Park, where boating is permitted. The park contains a playground and pavilions for parties.
