Flow is 211 CFS at Cooks Falls with a gauge height of 1.68 ft — down from last week's elevated levels and sitting right at fishable baseflow — with water temperature a cold 44.8°F, pushing trout tight to the bottom of deeper pools and slower runs. Expect a slow morning start with the best action developing as afternoon sun warms the surface and coaxes midday midge and BWO activity.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Blue-Winged Olive (Baetis) | 20-22 | Moderate | 11 AM - 3 PM |
| Midge (Chironomid) | 20-24 | Light | 10 AM - 2 PM |

| Stonefly (Little Brown) | 12-14 | Light | 9 AM - 12 PM |
Best Time Window
- 9 AM - 11 AM: Deep nymph the pools and pocket water as the sun begins to warm the canyon — stonefly and midge patterns on the bottom.
- 11 AM - 3 PM: Prime BWO hatch window with full sun and temps climbing toward 62°F — watch for rising fish in the flats and tail-outs, switch to dries and emergers.
- 3 PM - 5 PM: Late-afternoon caddis activity in the riffles; nymph the deeper runs as light fades and trout drop back into feeding lanes before dark.
Guide's Tip
From the benchWith water at 44.8°F, trout metabolism is sluggish — they're not moving far for food. Focus your drifts in the deepest third of each pool, right along the bottom, and slow everything down. Use a longer leader (12-14 ft) with 6X tippet in this clear, low water, and position yourself well downstream before you ever make a cast. The midday window between 11 AM and 2 PM is your best shot at rising fish when the sun warms the surface and BWOs start popping — watch the slow, glassy tail-outs and inside seams for subtle sipping rises, then switch to a dry or emerger pattern.
