Stratton Lock and Dam
The Stratton Lock and Dam is named after William Stratton and is the only dam on the Fox River (Illinois, USA) that is served by a lock system. It is located in Nunda Township, McHenry County, Illinois, and was built in 1907.
The facility is owned and run by the Illinois Department of Natural Resources. The lock operates for all powered, sail driven, or paddle propelled canoes or boats, even float tubes, at no charge.
