139,3 km – 140,9 km

Newboro Lockstation is located at the south end of a narrow isthmus that separates Upper Rideau Lake and Newboro Lake. A 1,5-km channel was excavated through the isthmus to join the lakes, and a lock was located at its southern entrance.

The operation of the Newboro lock was electrified in 1966, although the lock retains its original stone sloping walls. © Parks Canada
