Winter fishing on Grande Ronde River (Troy)
Steelhead hold in the Grande Ronde through the winter after the autumn run. In hard cold the canyon river can carry slush and shelf ice, and the steep roads to Troy can be dangerous in snow. Mild spells, when the water warms a little, are when winter fish move into the swing water again.
Seasons, closed sections and permits are set by the state and change. Check the current regulations before a winter trip, and never trust shelf ice or a forecast for your safety.
