Lock No. 31
Also known as: Lonesome Lock

Why it's listed
Lock No. 31, nicknamed "Lonesome Lock," is a canal lock on the Ohio & Erie Canal in Boston Township near Peninsula, Summit County, Ohio. Built between 1825 and 1827, it sits about 100 feet east of the Cuyahoga River in a secluded stretch between the former canal villages of Boston and Peninsula. The lock is a standard mitered-gate type with a chamber roughly 15 feet wide, built of cut stone and load-bearing masonry, and partly covered with concrete applied around 1905. Both gates are gone, though water remains in the chamber, and traces of a probable spillway lie close by to the southeast. Visitors can reach it only on foot after a considerable hike, and the main sound is Ohio Turnpike traffic half a mile north. Nearby Stumpy Basin, once a canal boat turnaround, is now used by Kent State University as an outdoor classroom for ecology students. The lock was listed as part of the Ohio & Erie Canal's regional importance.
Significance in brief: The lock is a surviving piece of the Ohio & Erie Canal, which reviewers described as important in regional development. It is a standard mitered-gate lock in a secluded stretch of canal between the canal villages of Boston and Peninsula. The form lists it under historic civil engineering landmark surveys.
