Lower Provo River Fishing Report 05/17/2026
Current Conditions Summary The Lower Provo is currently running at 400 CFS. At these higher flows, nymphing will be your most productive option. We have seen some moss and other debris moving through the river, but since the bump on May 8th, the water is now looking good. There are still some Blue Wings around, plenty of midges, and some early signs of caddis. The dry fly hatch is a little more sporadic and sparse with the higher water, but there are still some opportunities. Flow & Water Discharge: ~400 CFS. Clarity: Clear, but high wind days can flip the lake and create off color conditions. Water Temp: ~43°F Outlook: Good fishing ahead! Weather & Timing Best Window: 10:00 AM – 3:00 PM Hatches & Bug Activity Sow Bugs: All day Midges: Decent hatches in the early morning (#22-24). Blue-Winged Olives (BWOs): mostly on cloudy, cooler days, size #20-22. Eggs: The rainbows will still eat an egg this time of year. Caddis: Keep your eyes peeled, warmer days and later afternoons should be the best window.
