Clear water and low flows offer prime sight-fishing conditions, but midday heat and spooky trout demand early starts and evening sessions. Pack hoppers and ants for morning, nymphs for midday, and caddis and baetis dries for dusk.

Silver Creek is running clear and stable at 93 cfs with 67°F water, offering prime conditions for early-morning dry-fly fishing as Pale Morning Duns and Blue-Winged Olives hatch heavily.

Clear water and rising flows have improved conditions on the South Fork, with grasshoppers and stonefly patterns producing from morning through evening.

Upper Teton near Driggs is the better bet right now; lower stretches are hot and low. Fish the upper sections with small patterns matching PMDs, damselflies, tricos, and terrestrials.

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

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

Covers Jul 29–Aug 5

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.

Stable conditions with clear water and near-normal flows make Silver Creek fishable but challenging. Expect selective, leader-shy trout and a need for precise presentation and accurate pattern-matching. The upper Preserve is more wader-friendly; lower sections favor float-tube or bank access.
