Grande Ronde River, Washington Fly Fishing Reports & Conditions
My tips of the week
The river is brutally low now, which is good for fishing, but really hard on a drift boat and even inflatables are struggling to move down the river. 'Hoppers are the "deal" for the rest of the summer. The story on water temperatures are: Trout will continue to be active at 75 degrees, but will taper off if the temperature toward 80 (which is what we're seeing now) and above 80 degrees they will have little interest in your offerings. Bass will remain active through the warmer temperatures.

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

The smallmouth bass fishing is excellent above and below Hwy 129 and gets better the closer you are to the Snake. The trout bite is done until some rain and cooler weather at river-level return. My recommendation for 3X tippet is for fluorocarbon material. For nylon tippet 5X is best and 4X should be fine at these water levels.

7-Day Forecast

Daily temperatures at the river this week are in the 90s with lows near the 60s - no precipitation in this week's forecast. The Wallowas are out of snow to contribute to river flow, so now we are dependent on rain. NSIA included a news story that the Columbia Sockeye return has bigger and more fish than last year, which indicates that steelhead should be improved and also indicates that ocean conditions are improving which will lead to a decade of growing anadromous fish returns.
