I went to Clark's Creek on 08/13 and it was very low and much stealth was required. I used 7X all day and a little soft hackle wet fly that I tied up a few years ago that always works well for me there. It is very simple and here is the recipe:
Hook - Tiemco 3761 #20
Thread - 8/0 Brown uni
Tail - 3 - 5 Woodduck fibers
Abdomen - Two twisted strands from a mottled turkey wing
Rib - XFine gold wire
Thorax - Fine brown beaver (no guard hair)
Collar - Dark dun hen hackle 1 - 2 turns
I fish this fly blind or to rising fish. I angle the cast downstream but usually not straight but to the left or right of the fish dependent on how the current will carry the fly. I like to overshoot the cast a foot or so and then begin a slow hand twist retrieve. since the fish are rarely over 13" I don't break off many fish when they strike. I took five fish on it on the 13th including two wild browns and two stocked fish about 12".
I never use a rod longer than 6' 6" and shorter is even better as it is so easy to get hung up in the trees. I fished from the pool shown in the picture down to where the path comes down to the creek, about 200 yards. It was nice because no one was in front of me to bitch up the water.
I'd go again but there is so little water and so few fish it is not worth the cost of the gas fifty miles back and forth.
If anyone wants to go for smallmouth bass on the Susky above the Juniata during week let me know via PM. I have a jet bass boat and wouldn't mind some company. I did ok at a spot near a ferry crossing two weeks ago and there is a spot at Clemson Island that is good too but you need to be on the water at daybreak. At Clemson I wade fish as there is no ramp to put my boat in there. I ususally am able to go Tuesday through Thursday.
