Source: http://www.hhpl.on.ca/GreatLakes/Documents/Gilmore/default.asp?ID=s002 The Power Canal didn't change the shape of the river much, but it did greatly reduce the volume of water flowing through this area.

Posted by Emperor Wang 5/2/2005 7:08 PM | remove   Sure thing, Tijmen. Prior to the opening of the Seaway, this was the only canal that was built on the south shore of the Saint Lawrence. Built between 1842 and 1845, it was 11.5 miles long, had 9 locks, a total lift 82.5 feet, with 9 feet of water over the sills. The upper end is in what's now downtown Valleyfield, and the lower end (since buried) was in the town of Melocheville. It superseded a series of smaller canals built on the north shore of the river by the British Engineers starting in 1779, and was rendered obsolete (for navigation purposes) with the opening of the 14 foot Soulanges canal in 1899. Near the midpoint of the Old Beauharnois, water was diverted to the Canadian Light & Power company generating station on the bank of the Saint Lawrence just east of Saint Timothee. A section of the canal is still visible in Valleyfield, and the power dam building still exists (although landlocked and obsolete since the Saint Lawrence was essentially diverted by the new Beauharnois canal in the 1930s) but apart from that, relics of the old canal are few and far between. I hope to discover and document some more remains this summer. If this isn't enough info, search UER for "Beauharnois" and you'll turn up some photos and links to a few old maps. Cheers!

You can clearly see the towpath and many footpaths along the old canal route. I'll let you know the next time I'm cycling around the lake. We'll have to meet up and do some field research in this area.
