Here is a 1857 chart showing the rapids before the cut was made.

At that time the recommended track was to the east of Sugar Island, and through Lake George. See Thompson's 1869 Coast Pilot for directions:

In the roughly 12 years between publication of the chart and the sailing directions, it appears that Canada dredged the "middle channel" to 16 feet deep through Lake George.
By the 1878 version of Thompson's Coast Pilot, it appears to have been down to 14 feet through Lake George :
