176,3 km – 176,7 km

This lockstation is located along a 400-m excavated channel and a man-made basin. Earth embankment dams hold back the water in the excavated channel from the river that passes nearby. The locks are at the southern end of the excavated channel. A weir crosses the river at the entrance to the excavated channel, creating a slackwater section extending north to Jones Falls.

Winch and push bar mechanism, the most common operating system, is used for controlling the lower gates. © Parks Canada
