"Butcher's Knife" is
the third major pool and drop rapid on the Main Channel of the Ottawa River.
This rapid is known for its whirlpools. Mid
way down the rapid on river right below the hole known as "Chopping Block" is an
eddy which continuously recirculates back up into a major whirlpool. The effect is extreme
at higher water levels. The only way out after a swim at higher watery, is to scale the
canyon wall and wait (quite possibly for a long time) for your boat to flush through.
On river left at the very bottom of the rapid
is a series of smaller whirlpools. This rapid is an easy sneak on river left.
