Discharge from Libby Dam is 9000cfs and the river is in great shape. Water temperatures are terrific and there are no dog days of August here. The Kootenai is fishing well.
Dry fly action is steady throughout the entire day. Caddis and pmds are waning but still active in specific areas. Pmd spinner falls are getting lighter each day but also still occurring in the mornings over riffles and down through runs. If you see bugs, you’ll likely see rising fish. Make a good presentation and they’ll eat a size 16 parachute pmd, rusty or cream colored spinner, or an elk hair caddis perfectly well. Hopper action is solid now and we’re now fishing big bugs with a dropper for most of the day.
Nymphing the Kootenai River will always produce a few fish even during high sunshine. Look for fish in faster runs 2-6 feet deep and especially in boulder gardens and deep riffles. The last couple days have been very good. Water temperatures are perfect at 56 degrees at Libby Dam. Trout are feeding aggressively. Remember to get bugs down and keep them down. Keep a keen eye on your indicator and if you notice even the slightest change in speed, lift.
Look for fish in slower currents, buckets, tailouts, drop-offs and especially around cover and down rocky runs. Slip your bugs above and especially below boulders in the cushions as fish will be concentrated in soft pockets. This time of year fish will be holding in deeper runs 4-6 feet deep and in walking speed plus water currents. Don’t overlook off current areas either like back eddies, small foam pockets, and the top of runs where the current just barely starts to pick up.
It’s hard to believe September is already hear and the days are getting shorter. Shadows and shade are appearing in places much earlier in the day. Be brave and confident. Get out the bigger rods and throw streamers. This is actually a great time of year to pick up a big fish. Fish streamers slowly with a pulse now and again to make them look like struggling baitfish.
7 Day Weather Outlook: Expect a nice week of weather with sunny to partly sunny skies and daytime temperatures in the mid 80s.
