The river continues to drop making wading easier, with hatches strongest in the early morning through midday before heat shuts bug activity down. Bigger fish are scarce this time of year, but hoppers are starting to turn fish; the Bellevue stretch is low and warm so heading north is recommended for afternoon fishing.

Flows are still pushy below the Warm Springs confluence but strong waders can access most of the river. Fishing has been solid in the mornings with multiple hatches active; afternoon fishing is hampered by low, warm water on the lower river.

Flows are still pushy below the Warm Springs confluence but most of the river is accessible to strong waders; fishing has been solid in the mornings with multiple active hatches. Dry dropper rigs in shallow riffles and fishing seams of fast water are productive; avoid lower river in the afternoons due to warming water temps.

Green Drakes should be around for another week especially on the upper river, with caddis, PMDs, and crane flies mid-morning before activity dwindles as the day heats up. Flows dropping below 400 CFS has made wading and moving around the river easier.

The Big Wood continues to fish well with trout of all age classes being caught and solid hatch activity, though conditions may shift as temperatures rise. Wading remains challenging especially midvalley, but the river is dropping and opening up new access daily.

The Big Wood has started dropping after its last surge of runoff, but wading remains pushy and crossing is limited. Dry fly fishing has been fantastic with Green Drakes, Golden Stones, caddis, and PMDs active, while nymphs and streamers are also producing fish.

Flows have stabilized between 600-700 CFS after dropping during a cool down, but wading and crossing remain difficult. Fishing is possible but limited, with better opportunities for mobile anglers hitting multiple access points.

Flows are fluctuating and likely to bounce up again with returning heat, making wading unsafe in most areas. Fishable water can be found where the river braids and at easy access points.

Flows are dropping but still under 1,000 CFS, making full-day wade fishing impractical. Side channels and back eddies are fishable; river expected to be in great shape in a couple of weeks for the Green Drake hatch.
