BBC photo of the Rideau Falls in winter |
At the end of each winter, explosives experts lay dynamite in the icy river that runs through the heart of Ottawa, Canada. Why? And what does this do to the fish?There's a video clip that goes with this article, complete with dramatic background music, footage from last year's blasting operations, I assume.
If you're reading this in the UK, there's something on TV tonight that matches this blog!
Watch ice blasting in Human Planet: Rivers on BBC One, Thursday 24 Feb at 2000 GMTThe article that advertises it does not reveal what our blasting does to the fish; you'll have to watch the programme to find out.
