context_page_description: The Caldon Canal, opened in 1779, runs 18 miles from Etruria, in Stoke-on-Trent, to Froghall, Staffordshire. The canal has 17 locks and the 69-metre Froghall Tunnel.
context_section_description: Because the roof of the Froghall tunnel has always been extremely low, the 2003 restoration included lowering the water level in the pound after dredging, and thus the headroom in the tunnel was improved to 5 feet (1.5 m) with a beam of 6 feet 8 inches (2.03 m). Unfortunately the new moorings just past the tunnel remain relatively little used, as many modern boats are still too high to pass through the tunnel. A height profile gauge is located at the exit of Flintmill Lock 17 to indicate whether a boat has sufficient clearance to pass through the tunnel. The low height restriction would similarly affect proposals to reopen stretches of the Uttoxeter Canal to boating.
