Figured I’d do a trip report for Southern Utah as I couldn’t find much info online, and hope this can help anyone who’s ever here. Most people are unaware of the fly fishing here, and as a result I did not see anyone else fishing. stayed in Hatch Utah, where a river called the Sevier River runs. Caught many small browns but could not find any big guys. This section of river is known for having Mostly browns, and a few rainbow/cutthroat. Talking to one local I found out the browns were just not biting good right now. I then went 45 miles north through circleville. About 3 miles out of town we went right on us 59, where there is 9 miles of public roadside stream. This is an irrigation river that is only fishable when the flows are turned down, usually through the fall and winter. There was lots of slow water and a few good runs, I fished between mile marker 6 and 9. I saw no rises and set up a dropper rig with a black wooly bugger and a pheasant tail nymph about 12 inches down. Nearly every good run boasted several good hits and usually a fish. In three hours I caught a dozen rainbows. Pheasant tail nymphs, hairs ears, and different colors of wooly buggers worked good. One run produced 3 fish over 14 inches. Bites would come on the dead drift and when it swung, causing the flies to rise. Hope this helps anyone who is ever around here!
