assuming raging water from assumed snow melt off....still safe to do? (ccw)

How much snow do you have?

Water levels should be good in late May - but the big push from the melt will be long gone. I've paddled the falls chain in extremely high water and did not feel overwhelmed running downstream. Upstream would have been much more difficult. I would not anticipate any difficulties unless break up is astonishingly late or May is tremendously wet.

Ditto to Banksiana.

be smart, have your paddle in hand when pushing off, be ready to paddle right away. be willing to portage a little further to get further away from the rapids.

The ranger will tell you the safe points to hit and go over the portage locations with you before you push off.

Falls chain is really cool btw, really neat area.

Most of what Janice will tell you regarding high water is on her map.
