OBEY RIVER, CLAY COUNTY, TENNESSEE, February 24, 2007, 10:00 a.m.: Sixty-two degrees, overcast, and the water was very low. One could wade forever. The deepest pool was waist deep and most of the time it was ankle to knee deep. I started at Moody Landing and headed downstream. I started with two fly rig: 8 elk hair with an 10 inch trailer 18 FTBH. Although there was visible activity on top, no luck. After fishing the usual spots, I changed the trailer to a 20 black gnat, on top. No luck. As I began to wade into unfished territory, I came across a bend with a deep center that ran under a canopy of trees. The trout were on top, all over, at the same time. I looked like feeding time. After several casts and no strikes, I added an attractor fly, 16 san juan worm, brown, weighted with wet fly dressing, on an 8 inch trailer behind the elk hair. From the worm, I shortened the black gnat on a 6 inch trailer. The cast had no more than hit the water, when the trout took the black gnat trailer. It was an 8 inch stock rainbow that put up quite a fight. I was unusually tired. After releasing the rainbow, I continued to wade downstream rather than cast again. About 100 yards on down, directly below where the road is cut through the bluff, I found a pool that was alive with fish, they were feeding from the top and in some instances, jumping out of the water. What I found unusual, was that the activity did not stop even when I waded close to the fish. After several casts, I replaced the black gnat trailer with a 20 zebra midge. On the first cast, immediate strike. Just like before. The trailer fly had little more than sunk to depth when the trout hit the zebra midge. 8-10 inch stock rainbow. The three fly rig works great for me, with few tangles. I fished for 3 hours with only two tangles. The attractor fly is key. The trailer fly was not effective without the attractor san juan.
