The Stone Arch Dam

Welcome to the Atlas Obscura Community discussion of The Stone Arch Dam in Ontario. Ask questions or share travel tips, experiences, pictures, or general comments with the community. For the story behind this place, check out the Atlas Obscura entry:

The Jones Falls dam owes its strength and durability to the fact that it was constructed with the stonework running in vertical courses; a masonry wall standing on end so to speak. Apart from the Rideau Waterway, I have not been able to learn of any other vertically coursed masonry dams existing anywhere else in the world.

Vertically coursed masonry appears in a number of coastal defence structures, quays and in a few industrial reservoir walls in Cornwall and Devon, UK - all locations where strong resistance to lateral loads were required. I know there was significant migration from the mining areas here to Ontario… perhaps this is an example of vernacular traditions being carried alongside that migration.
