Designated as a Natural Historic Site of Canada, the Trent-Severn Waterway is composed of interconnected rivers, lakes, locks, and canals that twist through Kawartha Lakes.
There are 5 major locks that the waterway passes through over a span of 386 km.

- The Bobcaygeon lock was the first to be constructed on the waterway.
 - The Lindsay lock links the many communities of Kawartha Lakes.
 - The jewel of the Kawarthas is home to the Fenelon Falls lock.
 - The Rosedale lock offers a calmer area of the waterway for paddling and kayaking.
 - And finally, the Kirkfield lock awes onlookers with its size.
