River Conditions
The Lower Deschutes is back open after the brief seasonal closure that ended July 31st — welcome back! Flows are running a robust 3,920 CFS at the Moody gauge this morning, on the higher side for mid-August but well within fishable range for both wade and drift anglers. The river is running crystal clear, and that clarity is your best ally right now.
Water temperatures are the key variable to manage today. Early morning readings are coming in around 63°F — comfortable for redside rainbows. By the time afternoon heat peaks near 88–90°F in the canyon, surface temps will push into the mid-to-upper 60s. At those levels, fish stack into deep, shaded runs to escape the warmth. Practice quick releases and use barbless hooks.
Some residual wildfire smoke may linger in the canyon corridor from area fires active since early July. Check conditions locally before heading out, and adjust your timing accordingly — smoke inversions in the canyon can hang heavy in the early AM.
🌿 Active Hatches — August 12
- Caddis (various, #14–18): Heavy — the main event. Evening flight kicks off around 6 PM and runs strong through last light. This is one of the best dry-fly shows in the Pacific Northwest right now.
- Blue-Winged Olive / Baetis (#20–22): Moderate — look for risers in tailouts and slower seams between 7–10 AM, especially in overcast or smoke-filtered light.
- Pale Morning Dun (#18–20): Light — sporadic mid-morning activity, 9–11 AM window in shaded water above Sherars Falls.
- Midge (#20–22): Moderate — consistent at dawn in flat water below riffles.
- Golden Stonefly (#6–8): Light — fading for the season, but big attractor stones still draw aggressive strikes in fast pocket water.
🎣 Top Fly Recommendations
Dries (Evening Focus)
- Elk Hair Caddis (#14–16): The undisputed king of the evening hatch. Tan or olive, dead-drift or skated across current seams — trust this fly completely.
- Stimulator (#10–14): Doubles as a golden stone and an attractor. Works especially well in choppy pocket water above Sherars Falls.
- Parachute Adams (#18–20): Your go-to for the morning BWO and PMD window. Visible, versatile, deadly on this water.
- Chubby Chernobyl (#8–10): Works as a hopper in the mid-day hours and makes an ideal indicator for a dropper nymph setup.
Nymphs & Subsurface
- Pheasant Tail Nymph (#16–20): Classic baetis and PMD imitation. Fish tight to the bottom in morning runs and tailouts.
- Copper John (#16–18): Gets down fast at 3,920 CFS. Red or green — both have been productive on the Lower Deschutes this month.
- Zebra Midge (#20–22): Never leave the truck without it. Fish deep in slow pools from first light through mid-morning.
- Woolly Bugger (#6–8, black or olive): The low-light closer. Swing it through boulder pockets after 8:30 PM for the largest redsides of the day — and the occasional early summer steelhead.
⏱ Best Times to Fish Today
- 6:00–10:00 AM: Prime window. Nymph deep runs, target midge and BWO risers in tailouts before the heat sets in.
- 10:00 AM–5:00 PM: Midday heat slows the surface bite. Fish deep shaded runs with nymphs, or rest and scout your evening water.
- 6:00–8:30 PM: The evening caddis flight. Work dry flies along current seams in canyon shadow with short, precise casts.
- 8:30 PM–Dark: Streamer time. Swing a Woolly Bugger through boulder gardens for trophy redside rainbows.
📍 Access Points
- Harpham Flat (above Sherars Falls, Maupin area): Excellent wade access. Productive riffles and runs both upstream and down.
- South Junction / Macks Canyon (BLM): Drift boat access. More pressure near launch sites; hike in for solitude. Macks Canyon campground is an ideal base camp for multi-day floats.
- Locked Gate / Beavertail: Classic mid-canyon wade water with lower pressure than Maupin-area access.
- Sherars Falls area: Traditional Warm Springs tribal fishing site — respect all reserved tribal fishing areas and posted closures at all times.
Regulations: Lower Deschutes — artificial flies and lures only, catch-and-release for trout. The Lower Deschutes reopened July 31st. Verify current ODFW steelhead retention rules before fishing.
🎯 Today's Guide Tip
At 3,920 CFS the Deschutes has serious push — fish are holding in soft seams behind boulders, in cushion water ahead of rocks, and in deeper pools where current breaks let them rest. Don't wade to where you want to cast. Get low, stay back, and work precise presentations from the bank or soft water. The evening caddis hatch on the Lower Deschutes in August is one of Central Oregon's finest angling spectacles — be in position before 6 PM, have your 5x tippet rigged and an Elk Hair Caddis tied on, and let the river do the rest.
