Great fly fishing remains in the Teton River. All boat ramps are open, water is clear, cold, and of normal flow. Be wary of recreational floaters. Dry-dropper rigs using PMD life cycle patterns with yellow sally terrestrial insect and a few golden stone patterns should be in that fly box. Caddis flies take over during evenings. Large dry attractor patterns will bring up fish from sheltering canyon waters. These waters heat up most quickly on the river, so play and release those trout gently. From Hog Hollow downstream, PMDs are active during daytime hours with caddisflies active in the evening.

Many creeks are beginning to warm enough to slow activity of hosted trout. Palisades Creek is one of the slowest to warm because of cool subsurface water coming in from Lower Palisades and Upper Palisades Lakes. Bitch, McCoy, and Bear Creeks are in good dry fly conditions with PMDs, yellow sally, and caddis activity resulting in feeding trout.

Fishing in the upper Blackfoot River has slowed considerably because of very low flow and high water temperature. Early in the day is the best time to fish here. Terrestrial insects presented close to banks and at the head of large holes will interest the cutthroat residing there.

Birch Creek remains good fly fishing because of numerous springs flowing into it. Fishing on the Little Lost River drainage will be over in the next few weeks as it tends to warm significantly and decrease in flow during mid-summer.
