I was drawn today to another part of the Rideau system, back to a place where one of my daughters and I had gone fishing a couple of years ago. There's a dam here, used to control spring floods, and a lock for recreational boaters, which is used to bypass the 2.8m/9' height differential in the river. I had the area almost to myself, save for 2 local lads who were alternating between fishing and jumping 5m/15' off a small bridge into the cool waters below.
Note: all photos were shot at f11, ISO200 at varying shutter speeds with a 10-22mm or 70-200mm lens.

buoys act as a warning to boaters of the dam ahead
this scow is used for maintenance on the waterway e.g. to place buoys
