Sun Valley / Picabo Area Fishing Report – September 19, 2018
How long will the Hopper fishing last? We get this question a lot. The answer is until the first couple of hard frosts! We have fished Hoppers well into November in past seasons, so keep an eye on the weather and ground. If it gets warm and you are still seeing them hopping and flying, then by all means, fish them!
Silver Creek is seeing a decent October Caddis emergence in the evening. This should switch to early evening / late afternoon as daytime temperatures drop. The Fall Baetis is getting stronger and stronger, the Callibaetis is still present on calm afternoons. The Mahogany Dun will also begin to show more in the middle of the day as temperatures drop. Brown Trout are still making their spawning run and they are ripping into baits at low light. Needless to say the evening Streamer fishing can be very good! Looking forward expect more of the same, but with a narrower and narrower fishing window. The mornings are awfully cold for fishing these days!
The Big Wood continues to show its beautiful fall colors both below and above the water line. The changing leaves and backdrop on the Wood make it worth fishing for that reason alone. Add in a few colorful Rainbows and you have one heck of an awesome day of fishing near Sun Valley! Try fishing Hoppers, Red Quills and Baetis. You may find some October Caddis north of Ketchum. Streamers are also a great bet as well as large standard nymphs like a Pheasant Tail.
The Lower Lost is fishing well. Use your favorite red nymph, like a Copper John, San Juan Worm, or Micro-Nymph in red. If you want to fish the surface Crane Flies and Hoppers are your best bets. There are some Baetis present as well, but anglers willing to fish subsurface will find more action.
The Upper Lost has a few fish willing to eat flies, but there is a lot of walking between them. This area remains a great place to go to have nearly a whole river to yourself and after a busy summer, there is plenty of appeal in that statement alone!
Finally, the South Fork of the Boise continues to pump out the Fall Baetis hatches in the afternoons. This should continue as long as the mild weather holds. Hoppers are also a great bet in the canyon!
Happy Fishing Everyone!
