Re: Holy Water Levels, Again.
I know mankind has screwed with the eco system here (dams, canals, basins, etc), I just don’t understand how they impact. Indeed, there has been a lot of rainfall, but still.
I have read this is a factor. My understanding is construction on/development of wetlands and flood plains reduce natures ability to absorb flood water, which I guess leaves it with no where to go but the natural choke points like the Lachine Rapids in Montreal and Chaudierre Falls in Ottawa.
It seems to me though, like in 2017, there is a lot of water. I understand the cold winter caused for a greater than normal amount of snow melt (the St Lawrence watershed goes pretty far north). Seems that is a contributing factor.
Here are a couple of clips from the news.
This one is down town Ottawa, so down stream of Lake Deschennes where sailing is popular. Apparently this bridge is going to be closed for quite a while.
Here's a 100 year old dam on a tributary to the Ottawa that was over topped for the first time.
