Indian Lake, in northwestern Ohio, was originally a group of smaller lakes and wetlands occupying 640 acres. Over the years, the Lewistown Reservoir that served as a feeder lake for the Miami-Erie Canal was converted into Indian Lake State Park. Entrepreneurs were quick to jump on the opportunities Indian Lake offered. Sandy Beach Amusement Park offered roller coaster rides and other attractions and hosted concerts by nationally known big bands. Through the centuries, the character of Indian Lake has changed, and condominiums and permanent homes now dot the waterfront.
