At the same time, the combined weight of the two flies still allows you to use a small stick-on indicator that won't interfere with casting.

Culley from Jans said these setups are known to produce in the winter: No. 20 to 24 Desert Storm, Black Beauty, cream-colored UFOs and Diamond Midges.

If you see winter surface action, it is probably chironomids (midges). Adult midges look like tiny mosquitoes. Hatch sizes are generally in the No. 20-24 range. If you find dry flies that are small and difficult to see, you can try fishing the midge in tandem with a somewhat larger dry fly -- something that will float well and is easy to spot in the current.

If a big brown strikes the midge, you'll know it!

Dusty Kenner at the Trout Bum 2 fly shop in Park City started fishing the Weber when he was 7 years old. He reports excellent results with nymphs in the winter, but said that surface activity is generally rare in January through March.

Kenner said there are some spectacular hatches later in the season: No. 18-20 blue-wing olive in late March and April, No. 10-14 golden stone flies in June and No. 10-14 yellow sally in June and July.

The Weber River is famous for its caddis mega-hatches in early summer, when the bugs are so thick that you'll wish you had a headnet. I have been skunked on several occasions during these caddis hatches.

Kenner recommends swinging soft-hackle flies of the same size as the hatch to imitate emergers.

In late summer, when grasshoppers fall into the river from the hayfields, hopper-dropper combinations are effective.

In late November, huge browns from Echo Reservoir run up the river.

Mark Fasbender, a life-long student of the river, almost always fishes it dry, even in the dead of winter.

He has had success with small renegades (Nos. 16-18) in January and February when conventional wisdom dictates, "Go wet."

In the early spring when fingerlings begin to appear, Fasbender gets outstanding hookups with self-sinking streamers and Woolly Buggers. He casts these across the current and strips them slowly through the hole, like a fingerling fighting against the current.
