Flow is running at 533 CFS with water temps at 49.3°F — down from last week's 637 CFS and warming slightly from earlier cold snaps, keeping clarity fishable ahead of today's incoming storm system. Expect flows to bump and clarity to drop by Monday as 90%+ precipitation moves through; fish hard this morning before conditions deteriorate.

Best Time Window
- 7 AM - 10 AM: Pre-storm nymphing in deeper runs and current seams with heavy anchor flies before rain arrives.
- 10 AM - 1 PM: Prime BWO hatch window under overcast skies — watch flat tailouts for rising fish and be ready with dries and emergers.
- 1 PM - 3 PM: Transition to sculpin and egg patterns in deep pools and undercut banks as storm pressure drops and big browns go on the prowl.
Guide's Tip
From the benchWith a major storm system rolling in today and flows likely to jump by Monday, your window is this morning — get on the water by 9 AM and focus on the slower inside seams and tailouts where pre-spawn browns are stacking ahead of the weather change. Set up a tight-line or indicator nymph rig with a heavier anchor fly (Frenchie or Rainbow Warrior) to get down fast in the 533 CFS flow, and trail a small BWO nymph or midge 12–18 inches behind it. As cloud cover builds through midday, watch for BWO activity in the flatter water and be ready to switch to a dry or emerger — overcast skies are your friend for surface action. If you're still on the water by early afternoon and the storm is moving in, drop down to a sculpin or egg pattern and probe the deeper slots; big browns get aggressive and territorial as barometric pressure drops.
