Hey Mark,
I went to check out sewer wave today and while it looks really impressive!!! the water is doing really, really funny things right now, which makes it look like there is a lot of accumulated ice under the water, not safe!. Plus the current is pushing under the ice ledges by the shore! Be careful out there. Deschene looks a lot safer right now with a nice area of free water down stream. Have fun tomorrow, I'm back off to work!
