Flow has dropped sharply to 260 cfs at a gauge height of 1.39 ft — down dramatically from the 1,060 cfs spike reported a week ago — leaving the river running low, clear, and in excellent shape for technical presentations. Expect a cold overnight frost near 32°F giving way to a gorgeous sunny Sunday topping out at 65°F, ideal conditions for a midday BWO hatch.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Blue Wing Olive (Baetis) | 20-22 | Heavy | 11 AM - 3 PM |
| Midge | 20-24 | Moderate | 9 AM - 11 AM |
| Caddis | 18-20 | Light | 3 PM - 5 PM |
| Stonefly (small) | 14-16 | Light | 10 AM - 1 PM |
Best Time Window
- 8 AM - 10 AM: Midge nymphing in the deep, slow pools before the sun warms the water — fish will be stacked low and a tight-line presentation is key.
- 11 AM - 2 PM: Prime BWO hatch window under full sun — switch to dries and emergers in the flat tailouts and pool edges where fish will be visibly rising.
- 3 PM - 5 PM: Late-afternoon caddis and continued BWO activity in the riffles — work the faster water with a small olive nymph or CDC caddis before the light fades.
Guide's Tip
From the benchWith the river down to 260 cfs and running gin-clear, stealth is everything today — stay low, approach pools from downstream, and keep your shadow off the water. The BWO hatch should fire hard between 11 AM and 2 PM in the sunny conditions; position yourself at the tail of a pool and target individual rising fish with a 12-14 foot leader tapered to 6X or 7X tippet. Before the hatch kicks off, tight-line a small Baetis nymph or midge pattern through the deeper slots at the head of pools, keeping contact with the fly and watching your sighter for any hesitation. After the hatch fades, work the inside seams and eddies with a small olive nymph — fish will stack up in these slower lanes as the afternoon light drops.
