Three Rivers Ranch's Tip of the Week
Flows are steady at 141 cfs, which makes for great conditions to walk and wade in! Midges are producing in the mornings, tapering off towards midday. Afternoons and evenings boast sufficient PMD hatches, with emergers sitting in the film being a fantastic way of picking up some eats. Mostly subsurface nymphs throughout the majority of the day. 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 2026.
