Deschutes River Hatch Calendar at a Glance
The Deschutes River runs roughly 250 miles from its headwaters near Crane Prairie Reservoir to its confluence with the Columbia River at The Dalles. The stretch most prized for fly fishing is the lower canyon below Pelton Round Butte Dam, from Maupin downstream through the basalt canyon. Cold dam releases keep water temps stable and predictable through summer.
The Deschutes holds wild redband rainbow trout, a genetically distinct subspecies native to the Great Basin and Columbia Plateau. These are not hatchery fish. The river also holds brown trout and mountain whitefish. Access through the canyon follows a gravel road along the east bank, with BLM camping and boat launches at Maupin. Most anglers wade or drift boat the canyon water.
The Salmonfly hatch in late May and early June is the signature event on the Deschutes. Pteronarcys stoneflies the size of small birds blanket canyon walls and drive trout into a surface-feeding frenzy. The hatch progresses upstream over two to three weeks, starting near the mouth and working toward Warm Springs. Water temps in the 50 to 54 degree range are the trigger.
Outside the Salmonfly window, the Deschutes offers consistent dry fly fishing from March through October. Skwala stoneflies in March are the season opener. PMDs carry the summer months. The October Caddis hatch in September and October closes out the year with some of the best dry fly fishing of the season.

Pteronarcys californica
The Deschutes Salmonfly is a bucket-list hatch. Massive stoneflies blanket canyon walls from Maupin upstream through Warm Springs over two to three weeks. Water temps between 50 and 54 degrees trigger the emergence. Big redband rainbows abandon caution and feed aggressively on the surface. The hatch moves upstream, so you can time your trip to intercept it.
Recommended: Stimulator, Sofa Pillow, Chubby Chernobyl #4-6
Dicosmoecus sp.
One of the largest caddis in North America and one of the best fall hatches on the Deschutes. Afternoon and evening emergences in September and October trigger aggressive dry fly takes. Fish have been on smaller patterns all summer and react strongly to these big orange bugs. The hatch overlaps with BWOs in late September for excellent multi-hatch afternoons.
Recommended: Orange Stimulator, Buckskin Caddis #6-8
Skwala americana
The Skwala is the Deschutes season opener. When water temps climb into the high 40s in late February and March, these medium stoneflies start appearing on the surface. Fish that have seen almost no dry fly action all winter respond eagerly. The canyon section near Maupin is the go-to spot for early Skwala fishing.
Recommended: Skwala Adult, Olive Stimulator #8
Ephemerella inermis
PMDs are the backbone of Deschutes summer fishing. Morning and early afternoon hatches give way to spinner falls by late afternoon. Fish can get selective during heavy falls, especially on flat water. A well-presented Sparkle Dun on 5X tippet with a dead drift is the standard approach. June and July are the peak months.

Common Questions
The Deschutes Salmonfly typically runs from late May through mid-June. The hatch starts near the mouth of the river and progresses upstream through the canyon over two to three weeks. Water temps in the 50 to 54 degree range are the trigger. Watch for the hatch moving through Maupin first, then up through Warm Springs.
The lower canyon from Maupin downstream to Sherars Falls is the most celebrated section for dry fly fishing. This stretch holds the highest density of wild redband rainbows and sees the best Salmonfly and October Caddis action. Access is by foot or drift boat along the east bank BLM corridor.
Yes. Wading is the most common approach on the Deschutes, though the river is large and some sections are best reached by drift boat. The gravel bars and rock shelves in the canyon provide good wading access to most productive water. Felt-soled waders and a wading staff help on the slippery basalt. The current is strong in many reaches, so wade with caution.
Yes. Several sections of the lower Deschutes are managed as catch-and-release or selective gear water. Check current ODFW regulations before fishing. The most popular canyon water around Maupin is typically catch-and-release for trout with barbless artificial flies and lures. Steelhead regulations differ from trout regulations on the same river.
