Rock Island Lighthouse is located in the Thousand Islands about 4.5 miles northeast of Clayton, Jefferson County, New York, off of Fisher’s Landing. Originally commissioned in 1847, it is one of six lights put up along the St. Lawrence River to guide traffic to and from Lake Ontario through the waterway.  The Rock Island station is the best preserved, as all of its structures still survive. It was refitted in 1855, rebuilt in 1882, and moved in 1903. The light was closed in 1955 after more than a century of service. Today, the lighthouse and island are maintained by the New York State Office of Parks, Recreation & Historic Preservation.
