This is an estimate and needs to be worked out. Both the low and high end are SWAGs. Will update as more information comes available.
The Lanes Mill Road Bridge is the signal that you are about to enter a section of maybe 6-8 diagonal holes over almost a 1/4 mile of river. Some are better for surfing than others. The ones at the bottom have some eddy service. There is parking at the bridge, and the river is roadside through this stretch, so these could be done as a park-and-play.
