Rocky falls is on Rocky creek up from the Current river. The creek is very small, and nearly drys up in the summer. The falls are great to visit after a heavy shower, it is site to be seen w/ heavy run off, but as far as fishing goes, I wouldn't waste my time trying to fish any part of Rocky creek, to small and too many other good fishing on the river.
We have a cabin on the current river not far from there, and if we are there during a rainy day we will ofter visit the falls to see the site.
