Survey facts

How deep is Big Rideau Lake?

Ontario's survey draws its deepest contour at 91.4 m (300 ft). The bottom can sit a little deeper between contours. Depths are measured below the water level on the survey day in 1972, so they shift with the lake's level.

Not for navigation. These contours give depth below the water level on the survey day; levels and shoals change. Use Canadian Hydrographic Service charts where they exist.

Boating on Big Rideau Lake?

Driving a boat with a motor, electric ones included, takes proof of competency, usually the Pleasure Craft Operator Card. Paddling a canoe or kayak without a motor takes no card.
