The Peterborough Lift Lock is a boat lift located on the Trent Canal in the city of Peterborough, Ontario, Canada, and is Lock 21 on the Trent-Severn Waterway.For most of its life, the lock's dual lifts were the highest hydraulic boat lifts in the world, raising boats. This was a considerable accomplishment in the first years of the 20th century, when conventional locks usually only had a rise.In the 1980s, a visitor centre was built beside the lock. It offers interactive simulations of going over the lift lock in a boat, and historical exhibits detailing the construction of the lift lock.Residents and visitors skate on the canal below the lift lock in the winter.The Peterborough Lift Lock was designated a National Historic Site in 1979, and was named an Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1987.The Trent-Severn has a similar hydraulic lift lock, the Kirkfield Lift Lock, at its summit near Kirkfield, with basins of the same dimensions, but which has a smaller vertical lift.Description and operationThe lock has two identical bathtub-like ship caissons in which vessels ascend and descend. Both caissons are enclosed at each end by pivoting gates, and there are pivoting gates at the upper and lower reaches of the canal at the junctions with the caissons. The gates on the caissons fit into slots on the gates on the reaches, so that they open in unison.
