Bighorn River Fishing Report
Water flows are at 3,000 cfs and the water temperature is 62 degrees. The trico spinner fall is the main event and the best action is from 7:00 to 11:30 AM. If you’re on the river at sunrise, you may find fish up on trico duns. If the morning air temps are cool, the spinner fall will be somewhat delayed and won’t become heavy until 8:00. Warmer mornings see the spinners falling sooner. The black caddis hatch is falling off, but there is still some surface action towards dark. There are also some Pseudo (Pale Olive Baetis) mayflies and trico duns in the evening. A few fish are being taken on hoppers, from 11:30 to 2:00 seems to be primetime for this. Nymph fishing is slow after the trico hatch. You can take fish on sowbugs, scuds, Baetis nymphs, aquatic worms, and caddis pupa, but you’ll have to work pretty hard for them. Streamers are producing if you have some cloud cover. Aquatic grass is now an issue, so you’ll have to target the fast-water sections for nymph fishing.
Trico duns and spinners in the morning. Black caddis in the evening. A few Pseudos (Pale Olive Baetis) during the day.
