The Fork is running elevated flows with fish keying on faster water and responding to morning stone hatches, PMDs, and evening caddis and spinners.

Covers Aug 5–12

The Big Lost is dropping into low-flow summer conditions and fishing despite angler pressure. Expect hatch activity through the morning and afternoon, with both dry-fly and nymph opportunities. Move frequently to find fish that haven't seen multiple casts.

Summer conditions are prime on the South Fork with multiple hatches active and stable flows around 5,950 cfs. Dry flies and nymphs both work, pair them strategically through the Palisades to Heise stretch.

Dropping flows improve wading on the upper Henrys Fork, but high water temperatures demand smart positioning and early season timing.

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.

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.
