Community Update: Masonry Repair Project to Begin

November 2, 2017 – In November 2017, Parks Canada will begin work on the rehabilitation of the stone masonry at Poonamalie Lock 32 on the Rideau Canal National Historic Site. This project will preserve the lock allowing future generations to enjoy the waterway.

Last week, the construction contract for the project was awarded. In mid-November, the contractor will mobilize to site and begin installing a cofferdam - a waterproof barrier used to complete construction in water. They will then construct a temporary weatherproof enclosure to work throughout the winter. Heritage stone masonry repairs will be undertaken on the wing walls, approach walls, sluice tunnels and within the lock itself. Work will involve stone replacement, repair, repointing, and grouting. Additionally, new safety ladders will be installed within the lock.

This project will be completed in two phases throughout the non-navigation seasons – typically from October to May. The full project is expected to complete in spring 2019.

A Brief History of Poonamalie

The Poonamalie site’s original name was First Rapids, as it is the first lockstation encountered in the descent toward Ottawa on the Rideau system. Tradition has it that the name Poonamalie was derived from a town in India named Poovirundavalli where the British Army stationed a garrison in the early 19th century. An officer of the Royal Engineers felt the cedar-lined roads at First Rapids were reminiscent of those he had seen while serving in India.

The channel in this section of the Rideau Canal is nearly 2.5km and bypasses the original rapids in the Rideau River. In addition to the lock, earth dam, and weir, a defensible lock master’s house can also be found at this site. This building was originally built in 1842 and remains in use to this day.
