The class III whitewater section of the Upper Cumberland River starts at Cumberland Falls with 5 miles of moving water and 5 miles of flat on Lake Cumberland's headwaters. The takeout is the Mouth of the Laurel River Boat ramp aka Noe's Dock. Lake Cumberland covers the last few rapids in this section during summer pool, making the best rapids come in during late summer/early fall season as they draw down for winter pool the optimal time to run it. Levels vary, but 705 feet and lower on Lake Cumberland make for all the rapids to be in. This normally coincides with mid-August to September in the drawdown cycle.
