Sorry it has taken this long to respond to your questions. There is always a midge hatch of some sort on the Elk as the day progresses which will always bring some surface activity. I usually do not do much midge fishing and stick with nymphs and wets. I have been having pretty good success with a #12 flymph in brown and a #14 bugger in olive or black. A brown wet fly stripped quickly will also bring you some results. Is there any public access to the Shippman Creek? I have never fished the Harpeth so I may check on it more. I do not have to have trout to fly fish. I just need anything to jerk on the flyline. I guess I am one jerk waiting on another jerk!
