Today's 3D Thursday blog post is one I've been working on for a while. It's a two-part series—with lots of 3D content—on the aqueduct that runs through LeBreton Flats. URBSite did a great (2D) post on the history of the Fleet Street pumping station, which is the subject of
part 2, coming next Thursday. Reminder: 3D photos are best viewed full screen with a dark backdrop.
The first image that comes to my mind at the thought of the word "aqueduct" is a high stone-arch wall dating from the Roman empire. But really, it's just any conduit that carries water, usually by gravity. In fact, as
this Discovery Channel special shows, most of the Roman aqueducts were on, or under, the ground level.
Ottawa's aqueduct is in a channel and partially buried under what are technically considered bridges. In the 3D photo above, taken from atop the escarpment, you can see the bottom end of the aqueduct, where it leads to the historic Fleet Street water pumping station and Pooley's Bridge in the foreground, and you can sort of follow it backwards along the line of trees through LeBreton Flats, curving back to the Ottawa River behind the condos of 250 Lett Street on the right. I don't expect you to see all that from the vantage point of the photo above, though if you zoom in close (zoom gradually if you can so your eyes can adjust along the way) you can make out the parkway bridge over the aqueduct inlet.
Here's where it comes off the Ottawa River, first passing under a prefabricated steel bridge that carries the Ottawa River Pathway. Nepean Bay in the Ottawa River is at the left, and the water headed to the aqueduct flows toward the right.
