Henrys Fork is running stable flows around 1,300 cfs with clear conditions. Watch for afternoon thunderstorm turbidity on the upper water.

Mutant stones are emerging on the South Fork with flows holding steady around 5,950 cfs. Early and late windows offer the best action for stone patterns.

The Teton is running low with clear skies and warm temperatures; target deeper pockets and shaded areas during peak heat.

Lower flows have eased access on the South Fork, but heat makes fish selective—fish early and late when hatches are active.

The Big Lost's North Fork and main stem are in good shape heading into early August, with manageable flows and morning hatches of Tricos and PMDs. Plan to move around the East Fork's heavier pressure and pack attractors in multiple sizes.

The Henrys Fork is steady and slightly below normal with clear skies and manageable flows for mid-summer fishing.

Flows have eased to 5,950 cfs, opening fresh wading water on the South Fork. Golden Stones and PMDs are active, but expect selective fish and plan your best efforts for low-light periods.

Expect high flows to keep the Big Lost challenging early in this outlook window. Water levels should trend downward as the week progresses, gradually opening up wading opportunities on the lower section. Scout the upper valley during high water; plan a return trip once flows recede.

Lower Henrys Fork is in the thick of seasonal hatching activity. Expect caddis and PMD spinner falls to drive the evening bite, with daytime action sporadic but present. Green Drakes should arrive shortly.
