Lock 21 - Peterborough Lift Lock

Trent-Severn Waterway

The Peterborough Lift Lock, located in Peterborough, Ontario has a length of 36.6 m (120 ft), a width of 9.7 m (32 ft) and an average lift of 19.8 m (65 ft). The Peterborough Lift Lock and the Kirkfield Lift Lock are the only two hydraulic lift locks along the Trent-Severn Waterway.

The lock was formally opened on July 9th, 1904 and with a lift of 20 m (65 ft) it is the highest hydraulic lift lock in the world. The lock was designed by Richard Birdsall Rogers. Rogers was a civil and mechanical engineer and grandson of Richard Birdsall, a Provincial Land Surveyor who had surveyed most of the Peterborough area.

In 1884 R.B. Rogers was appointed Superintending Engineer of the Trent Canal, a position he held until his retirement in 1906. In 1896 he travelled to Europe to study hydraulic locks in Belgium, England and France. Upon his return to Canada, Rogers prepared the plans and construction of the project was carried out by his Chief draftsman W.J. Francis.
