► Small worm imitations, such as a tan San Juan Worm, may pick up fish if drifted near the bottom--especially if there's an angler wading upstream from you.

► If you don't see rising fish, forget the dry fly and use a small nymph, such as a size-18 Copper John or Pheasant Tail, drifted near the bottom.

► Small black stoneflies (winter stones) may be available near the end of the month.

► Small worm imitations, such a tan San Juan Worm, may pick up fish if drifted near the bottom--especially if there's an angler wading upstream from you.

► Be prepared for fussy fish. They see lots of anglers all year, so you may need a 6X or 7X tippet, a 50-foot cast, and a downstream presentation when fishing a dry fly.

► Most trout will have migrated up the river, making the headwaters section the best place to seek them because the water is warmer there.

► When you come here for winter fly fishing, set your expectations: if you can get in three hours of good dry fly fishing, you're lucky.
