Flow is running 499 cfs at the Dotsero gauge with water temps at 44.1°F — cold but fishable, with clear conditions favoring precise, drag-free nymph presentations in slower seams and tailouts. Sunny skies and a high near 59°F today will warm the water slightly midday and trigger the best Baetis and midge activity of the day.

Best Time Window
- 8 AM - 10 AM: Early nymphing with worm and egg patterns in deep pools before the sun hits the water — fish are stacked and hungry.
- 11 AM - 2 PM: Prime BWO and midge hatch window as air temps climb toward 59°F; watch for surface activity and be ready to switch to a dry or emerger.
- 2 PM - 4 PM: Afternoon nymphing in riffles and pocket water with Baetis and midge nymphs as the hatch winds down and fish drop back into feeding lanes.
Guide's Tip
From the benchWith 44°F water, trout metabolism is slowed — slow your drift down and get your flies deeper than you think necessary. Set your indicator depth to 1.5x the water depth in the pools and run your nymph tight to the bottom through the slower inside seams and tailouts where fish are stacking up to conserve energy. The warmest part of the day (noon to 3 PM) is your best shot at a surface eat — watch for subtle sipping rises in the flat water above riffles and switch to a small dry or emerger the moment you see them. Keep your tippet fine (6X) in this clear, low-pressure water.
