History
Lock 20 Ashburnham
Constructed: 1896-1900

Located on the shore of Little Lake and the Trans-Canada Trail, the lock provided access to the artificial canal cut leading to the Peterborough Lift Lock. Originally the site of private homes, the property was converted to workshops, a maintenance yard and docking area for the canal work crew. Today the original Lockmaster’s Watch House from Lock 20 is being used as a mini-museum at Lock 32.
