Three Rivers Ranch's Tip of the Week
The Owyhee is 32 CFS and fish are in full spawn. Fish that are eating can be found in the deep pools. We advise to stay away from riffles and redds. Call our Boise Fly Shop at (208) 939-6065 to find out the latest info on the Owyhee River and to Book a Guided Trip for 2024.

Three Rivers Ranch5-Day Outlook as of 11/20/25
Flows will stay steady for the winter. Best to leave the fish alone to spawn, or target slow, deep water. You can still find some risers in the slow stuff, just avoid riffles and spawning fish.
