I fished both north river and tellico this past Saturday. I didn't catch any on north, as I was teaching a friends son how to fish with a fly rod. When we got over to tellico the fishing was much better. Nothing on beetles but pink weenies were producing well. Anything not gated off had campers in it.
Sour wood is a campground right on the river in between green cove and the hatchery. Last time I stayed there it was free though it is marked with the same style sign marking the other camps. Personally I prefer dam creek walk in campground as most folks don't want to carry their stuff from the car to camp and pass it on by. Usually a lot more peaceful there.
