Ottawa River Buoys & Lighthouses




Lac Deschênes Buoys

This is a list I have compiled of GPS buoy locations on Lac Deschênes, plus photos of them, too.

The postions were located on sail-bys and thus are only accurate +/-50 feet (15 m). Some positions are approximate and are labeled as such. I will attempt to refine these over time.
