Sun Valley / Picabo Area Fishing Report – August 22, 2018

Cooler nights have given us a hint that fall is coming. The local trout population sure knows it. The Brown Trout have started their upstream migration into ideal spawning areas and both Browns and Rainbows are packing on the calories. The nighttime temps have certainly cooled the water and the fish are acting accordingly.

Silver Creek is fishing well as the day progresses. The Trico and Baetis in the morning has been less than spectacular, but the Hopper fishing when it’s windy in the afternoon and the Callibaetis when it’s not windy, has been off the charts great! Anglers staying until dark will find great fishing as the sun sets. Hoppers are very effective under low light and the Mouse fishing will continue to get better and better as fall approaches.

The Upper Lost and Big Wood remain strong fisheries. This should continue and even improve as we move closer to fall. Be sure you have the Western Red Quill in your fly box in the coming weeks as this hatch is the next big one. In the meantime keep fishing Hoppers and small attractors like Parachute Adams. The Streamer fishing is also good, as the fish in these systems also try to pack on some weight before the true cold sets in.

The Lower Lost River is fishing pretty well. Flows still make moving about a bit of a challenge, but the Trico action in the a.m. can be great if you are in the right water type. Mainly the flatter the water the better! Crane Flies are active as well as a variety of Baetis. If nothing is going on surface wise, then try nymphs like Copper Johns and Zebra Midges. Fish these in Red and Black colors and be sure to move slowly looking for sight Nymphing opportunities.

The Fall is also a great time to get out on Magic Reservoir. This fishery really lights up as we move toward cooler days and nights. If you’ve had enough river fishing this summer, Magic is a great break from the norm!

The South Fork of the Boise, although busy most days, still has good Hopper and Pink Alberts fishing throughout the day. The flows remain at driftboat levels and this should remain the case for the rest of the month and most of September is the summer heat continues.

Have fun out there, and don’t forget, the Picabo Angler Shooting Preserve is now open for you bird hunting enthusiast out there!

Happy Fishing and Wing Shooting Everyone!
