Big Eddy is a deep pool and whirlpool on the John Day River in Sherman County, Oregon, not a waterfall or a rated whitewater rapid, near Cottonwood Canyon State Park.
The falls
The whirlpool forms where the John Day braids around Hole Island at a sharp bend, and it is most visible at low water, with the main current running against basalt cliffs. Reach-wide whitewater ratings for this stretch of river do not apply to Big Eddy itself; no source assigns it its own class.
Getting there
Oregon State Parks manages Cottonwood Canyon State Park, open for day use and camping year-round. The foot-only Hard Stone Trail runs upstream from the park toward Big Eddy; the out-and-back route is 5.2 miles with 110 feet of gain to its Mile 42 Bend endpoint, and Big Eddy is reached before that point. The first mile is open year-round, while the full route is open October through January. J.S. Burres serves as the nearby boat launch, and there is no cell service. No day-use parking fee is listed. Boaters need a year-round online Bureau of Land Management permit for the John Day River; a use fee applies in high season on specified segments, and low-season boating also needs an Oregon Waterway Access Permit.
When to go
The whirlpool is most visible at low water. Open-flame restrictions run from May 15 through November 1, 2026, and no closure was posted at Big Eddy as of this check.
On site
American Whitewater rates its Clarno-to-Cottonwood reach, 68.9 miles gauged at the John Day River at Service Creek, as Class II-III. The Bureau of Land Management calls the broader segment Class II-IV because it includes the separate Class III-IV Clarno Rapid far upstream, but Big Eddy is not listed as a named rapid or a portage on either account. Recommended minimum flows for the reach are 1,200 cubic feet per second for drift boats, 1,000 for rafts, and 300 for canoes or inflatable kayaks if Clarno is lined or portaged, with no maximum given. Dogs must be on a six-foot leash. Hazards include heat, no cell coverage, rattlesnakes, cougars, ticks, and a cold, moving river.
History and name
The name reflects the feature itself: a deep pool with a whirlpool at the sharp river bend.
