Flow is running at 590 CFS with water temps at a brisk 44.1°F — down from last week's readings and cold enough to push trout into slower, deeper water where they're feeding subsurface throughout the day. Clarity is good heading into the weekend, and with sunny skies and a high near 60°F, midday warming should trigger the best surface and near-surface activity of the day.

Best Time Window
- 8 AM - 10 AM: Early morning streamer and stonefly nymph fishing in riffles and along undercut banks before the sun hits the water.
- 11 AM - 2 PM: Prime dry fly and emerger window as midday sun triggers BWO and midge hatches in slower pools and tailouts.
- 2 PM - 4 PM: Continued nymphing in deeper runs as afternoon light holds — fish will drop back down after the hatch, but remain active in the warmest part of the day.
Guide's Tip
From the benchWith water temps at 44°F, trout metabolism is slowed — fish are holding in the deepest, slowest water they can find, typically the bottom third of pools and the inside seams of deep runs. Get your nymphs down fast with enough weight to tick the bottom, and slow your drift way down. The best window today will be 11 AM to 2 PM when the sun warms the water surface a few degrees and triggers both midge and BWO activity — watch for subtle rises in the flat water below riffles and be ready to switch to a dry or emerger quickly. For streamers, target undercut banks and boulder gardens in the early morning before the sun hits the water, using a slow, erratic strip to imitate a cold, sluggish sculpin.
