I started this series a couple of weeks back at Green Island, and so conclude it here as well.
The French explorer Samuel de Champlain came up the Ottawa River in 1613. He and his party arrived in the Ottawa area, where waterfalls on the Ontario side caught his eye. Champlain thought they had the look of a curtain- a rideau in French- and so named them that. The waterfalls and the river continue to bear that name. It is actually two falls, winding around Green Island, dropping 9 metres (30 feet) into the Ottawa River, and giving their name to the parkland around it. This is the western branch.
Crossing over the hydro dam above the falls, one gets a good view of the Ottawa River, Gatineau on the far shore, and the outlet of another river on the Quebec side. That is the Gatineau River, which also converges on the Ottawa River in the same vicinity. This area would have been well known for thousands of years among the various First Nations peoples living here.
The eastern branch of the falls are the more extensive of the two.
If you look closely, you might see the duck just above the brink, eating the vegetation growing in the water. The water might be swift, but it's shallow, and the duck has no problem staying in the flow.
The best view of the falls are from the river below, and one will often see boats down there.
These views, taken at different times in the afternoon, are from the eastern platform. It surprises me that it's taken this long for me to come out here and photograph the falls for the blog.
