The gauge is actually on the West Branch of the Oswegatchie after the Middle Branch joins it. There is no actual gauge on the Middle Branch. Keep this in min
Really cool mini-gorge like rapid. The river takes a 90 degree turn to the left and significantly narrows. The river looses some vertical fairly quickly through this rapid in the form of several drops including 2 fairly large drops. It also takes another 90 degree turn to the right and one more turn to the left. Very impressive rapid. Definitely scout and/or carry right.
