Bonnechere river, Fourth chute

Some fantastic hard rapids in a square-cut limestone gorge. Inspect and walk up on the right bank. There is a decaying dam after the bridge that has quite a steep drop-off. A few twists and turns later, the main drop comes up, with some powerful boils at the bottom. In low water this drop has a hazardous narrow slot at the base. The image below shows the main drop at a gauge reading of about 65 cumecs.

To get there; Take highway 60 through Renfrew, heading West. This takes a right turn in the town of Douglas. Before you exit Douglas, turn left onto Fourth chute road. After 6 km, cross the river and park on the right. On river left is the Bonnechere show-caves, a good option for anyone that isn't paddling. Unless you are claustrophobic.
