Stratton Lock and Dam
The Stratton Lock and Dam, known until 1991 as the McHenry Dam, is named after William Stratton and is the only dam on the Fox River (Illinois, USA) that is served by a lock system.[citation needed] It is located in Nunda Township, McHenry County, Illinois, and was built in 1907.[citation needed]
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.
