Arrived at Tan Vat about 6:30. Only car there, not to bad for a Sunday. Started with a big streamer trying to get a nice brown but no luck. Then tried nymphs, rubber legs, little streamers and nothing produced. Then noticed a nice brown looking up and the only dries I had on me were leftover hoppers from my trip to the White. First cast, the brown came out and drilled it. Decided to keep the hopper and caught a few more browns and a really nice rainbow. After the sun came out a THICK hatch started (assuming it was tricos?) and not a whole lot of fish were rising, but when one was, it was rising once every 4 or 5 seconds. Went back to the car and looked for some small dries (I didn't have any tricos) and I threw every dry fly I had. Cracklebacks, elk hairs, griffiths gnat, and a few personal patterns. Didn't get a single bite. Couldn't believe it. Decided to throw and big Madam X and finally got a rainbow. Caught a few more on an egg and missed and 18+ inch rainbow. Got crowded and called it a day. Not a bad day but not great by any means.
