Stoneflies are out in force below Ashton Dam.  Up to now, big nymph imitations have brought best success, but some fish are beginning to take dries.   From Warm River to Ashton, fish are responding well to big stonefly nymphs.  Look for fish to begin taking dries here later this week.  Don’t forget that caddis life cycle patterns will work well.  Flows above and below Ashton Dam are a bit above normal but constant. The river is a bit discolored from Warm River to Ashton, but not enough to impact fishing.   Box Canyon remains a bit slow, but a few fish are responding to deep nymphs and streamers.  No stonefly nymphs moving in significant numbers to date.  Fall River run-off still makes for poor fishing below Chester Dam unless you have a boat and are willing to fish deep.
