Kingsley Lake is an almost circular lake of about 2,000 acres (8.1 km²) in North Central Florida, about six miles (10 km) east of Starke, Florida. According to some sources, it is the oldest and highest lake in Florida, located on the edge of the Trail Ridge formation. The lake is a very stable lake with a sandy bottom. Its deepest part is about 90 feet (27 m). Kingsley lake is so nearly circular that pilots call it the Silver Dollar lake.
