Grande Ronde River, Washington Fly Fishing Reports & Conditions
My tips of the week
'Hoppers are the focus now and will last into the fall. My approach is to start with a black woolly bugger and fish it until late morning, then switch to 'hopper patterns until the fish lose interest late in the day. Trout in this river cope with the warm water until it approaches 80, then bass usually fill in, so go have some fun.

Grande Ronde River Description

The Grande Ronde River slices a 3,000 foot deep canyon through flood-basalt flows that originated from Grande Ronde volcano when it was active 15 million years ago. This is a moderate-gradient freestone river supporting abundant caddis and stonefly populations and good mayfly hatches.
The arid climate at the bottom of the canyon is warm in the summer and generally moderate through the fall and spring with ...

Techniques & Tips

Blind casting along the shore should be productive now with 'hoppers on the scene. Mayflies and caddis will be active early and late in the day. My recommendation for 3X tippet is for Fluorocarbon tippet. It has the same visibility as 5X and much higher breaking strength. A disadvantage fluoro is that it sinks and probably won't work with small dry flies.

7-Day Forecast

The fishing over the weekend was excellent for smallmouth below Hwy. 129 and especially below Shumaker to the Snake River and good for rainbows and smallmouth above Hwy. 129. All week it's mostly sunny with highs in the mid to upper 90s and lows near 60. The rainbows are used to the warm water conditions of the Ronde and continue to feed actively until the water temperatures move into the 80s.
