Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.

Hey 👋
I've been fishing clear creek in golden Colorado, waters icy, I've been out past two days. Swinging black, olive and white streamers. Poison tounges, black beauties and zebra midges - no hits.

Any special advice for Colorado Rocky Mountain frozen creeks?

Thanks!!

Fgfg,

Nice to see another Coloradan. For Clear Creek, the hatches will primarily be midges. But mayfly nymphs should be on the move as well. You may want to try a combination of these in a 2-nymph set up.

Try:
BH Pheasant tail sizes 16-20.
BH Brassie 18-22 in olive, cream, or gray.
BWO Para. 16-22.
Midge dry flies 20-28.

I hope this helps. I know it works well on the Big T.

Also, stay warm and please be careful on any ice. Most of all, be patient. They will be deep in holes, and tucked up tight under rocks. Clear Creek can be very tough this time of year, but obviously better after run off.

If you continue using streamers, keep them as close to the bottom as you can tapping the rocks.

One more thing. Use smaller streamers than what you would normally use. I would use something 1 1/2 inches long at most.

If you are in really cold water the fish may not be willing to move much. I know we've had an unseasonably warm February, but this last front has dropped temps back to winter. Keeping speed in check will become important again.
