Conditions

The Lochsa has settled into classic late-summer low water, with flows at 427 cfs as of August 26 and continuing to fall. Trout are tucking tight to pocket water, riffles, and softer current seams where they can hold in comfortable lies. Surface activity is picking up, so watch for rises alongside your subsurface work. Fish a Chubby Chernobyl #10 or #12 with a small jig nymph in these classic summer slots to connect with concentrated fish.

Techniques

  • #10 or #12 Chubby Chernobyl paired with small jig nymph is excellent prospecting setup; pull off dropper and fish dries as surface activity increases.
