Bighorn River Fishing Report

Last Updated:
Current Report:
Well, the Tricos have made a reappearance and are providing good dry fly fishing. These are the bigger Tricos (sz. 20). The duns come off at daybreak and the spinners start to fall around 8:30 AM. Water flows are slightly above 4,000 cfs which is an excellent flow for late in the season. Nymph fishing has been fair to good on scuds, sowbugs, San Juan Worms, and caddis pupa. Fish can be taken on Tung Teaser or caddis pupa patterns throughout the day. They're probably eating the Tung Teaser as a drowned trico spinner. Anglers need to concentrate on the faster water because of the growth of aquatic grass. Still a few fish eating hoppers. Some Pale Olive Baetis (sz. 22) in the afternoon.

Streamer fishing has been steady but you'll need to know how to slap grass.
