The Deschutes River in Maupin flows through dramatic canyons with crystal-clear, cold waters fed by mountain springs, offering prime riffles and deep pools that attract avid fly fishers seeking wild trout in a scenic, arid landscape.

Overall Fishing Conditions

Fishing on the Deschutes River on September 20, 2025, looks promising with sunny skies and temperatures reaching 88°F, leading to active fish in the clearer, lower flows; I'd rate the conditions an 8 out of 10, as the water temperature around 63°F supports good trout activity despite the slightly reduced flows that might make fish more cautious.

Insect Hatches and Their Timing

Late September hatches on the Deschutes typically include reliable midges and small caddis in the mornings and evenings, with possible terrestrials like ants or beetles stirring up action during the warmer midday hours when winds are light.

Species to Target

Focus on rainbow and brown trout, which are abundant and feeding actively in these conditions, while steelhead might start showing up in deeper runs as fall approaches.

Top 5 Fly Patterns to Use

• Size 16-18 Parachute Adams for mimicking common hatches in the clear water.
• Size 12-14 Elk Hair Caddis to match evening caddis activity on the surface.
• Size 18-20 Zebra Midge for subsurface fishing during low-light periods.
• Size 10-12 Woolly Bugger in black or olive for prospecting deeper pools.
• Size 14-16 Beadhead Pheasant Tail nymph to target fish holding in riffles.

Best Times of Day to Fish

Early mornings around sunrise offer the coolest water and best hatch activity with minimal wind; late afternoons into dusk provide another prime window as insects emerge and trout rise more predictably under the waning crescent moon.
