Deschutes River Fishing Report — August 15, 2026
Flow: 3,920 CFS (USGS Gauge #14103000, Moody near Biggs — provisional data)
Water Temp: 65.7°F (recorded 5:45 AM PDT; expect afternoon temps approaching 68–70°F)
Clarity: Crystal clear
Overall Rating: Good
Current Conditions
The lower Deschutes is in solid mid-summer form heading into the heart of August. Flow is running 3,920 CFS at the Moody gauge (near the Columbia confluence) — flows in the Maupin corridor run somewhat lower as irrigation diversions pull water upstream. Clarity is exceptional, as expected this time of year. Water temps hit 65.7°F at first light, well within the safe zone for redband trout, though afternoon temps can push toward the 68–70°F threshold. Fish your best windows: first light through 10 AM and again from 6 PM through dark. Note: intermittent wildfire smoke has been reported in the Maupin area this season — check air quality before heading out.
Hatch Report
August on the Deschutes is caddis season — full stop. Evening hatches from roughly 7 PM into darkness are explosive right now. An Elk Hair Caddis (#14–#16, tan or olive) is your anchor fly for the evening rise, and a Stimulator in orange or yellow covers faster pocket water with authority.
Mid-day belongs to the hopper. Slap a Chubby Chernobyl (#8–#10, tan or golden yellow) against grassy banks and undercut edges — aggressive daytime takes from Deschutes redbands are one of the great thrills in Central Oregon fly fishing. Morning anglers will find a few Pale Morning Duns and early Trico spinners; a Parachute Adams (#18–#20) covers both cleanly.
Subsurface, dead-drift a Pheasant Tail Nymph (#14–#16) or Copper John through deep riffles and behind boulders. Nymphing outproduces dry fly fishing on numbers throughout the warmest hours. Swinging a black or olive Woolly Bugger on a sink-tip through shaded canyon runs can connect with the larger fish pushed into cooler, deeper lies by afternoon heat.
Best Access — Maupin Area
- Above Sherars Falls: Heritage Landing, Harpham Flats, and Maupin City Park offer solid wade and walk-in access to excellent pocket water.
- Below Sherars Falls: South Junction, Macks Canyon, and Trout Creek (BLM) provide outstanding walk-in access to less-pressured lower canyon water.
- Sherars Falls is a mandatory portage — Class V, unrunnable by standard watercraft.
Hazards & Notes
Flows at 3,900+ CFS make wading difficult — sticky soles and a wading staff are a must. Afternoon canyon temps can hit 95–100°F; carry plenty of water. Rattlesnakes are active on rocky slopes and cliff faces. Catch-and-release applies for redband trout — check current ODFW regulations before your trip. Drift boaters have excellent water throughout.
