The Middle Deschutes is a decent bet from Bend to Lake Billy Chinook. The water is high for winter as the canal systems are off now. Indicator fishing with stonefly nymphs is your best bet. I’d run a trailer behind the big nymph with something small and flashy like a Frenchie or Psycho Prince.
Spoke to a customer who had a great session of catching brown trout near Tumalo last week plus Brad and Eric from the shop went down near Steelhead Falls a few days ago and did well.
