AL Trout Bum--It's too late now, but unless my old eyes fool me badly, you were within a half mile of where you could almost certianly have caught a few fish. I'm almost certain the waterfall you show emptying into a big stream is Toms Branch Falls on Deep Creek. If so, you could have walked a bit farther, headed up Indian Creek, and likely dealt with rainbows (small though they would have been). It almost always clears up and goes down before Deep Creek and doesn't get a lot of pressure.
It is, however, tight as a miser's purse strings..
