I grew up about 2 km from there, but don't remember the cliffs that well. I have a feeling that there's a small bank beneath the cliffs that would preclude DWS along most of it, but it'd certainly be worth a look.
If it was worthwhile you'd need to pole the bottom every time as well, because that section of the river is pretty commonly infested with old wood and such that'd spoil your day if you landed on it. |
