Tri-Lakes

I would recommend going to the Peterborough and Kawartha Touriam Association on George St. in Peterborough. They carry very detailed, laminated, bathymetry maps. A little pricey, but worth the $$$. Upper Buckhorn should not be all that bad with the larger vessel, but water levels are a little lower right now. Call the Trent-Severn Waterway and check the most up to date levels if you are concerned.
