John Day River, Oregon

Spray to Service Creek

Highway 19 follows the river from Kimberly through Spray to Service Creek, and this is the best bank access on the mainstem: Mah-Hah Outfitters points bank anglers to the road from the Highway 207 junction upstream, and the BLM Service Creek recreation site has a campground and launch. The Spray to Service Creek float is bass water that needs no BLM boater permit, since the permit section starts at Service Creek.

Service Creek to Clarno

Service Creek is the put-in for the Wild and Scenic canyon. The 13 mile day float to Twickenham is the most popular stretch on the river, and the full Service Creek to Clarno run is 48 miles of Class II to III water that most parties do in three days. Below Clarno the river runs 70 more miles to Cottonwood Bridge through Clarno Rapid, a Class III to IV drop that can be unrunnable at low water and is the reason drift boats stay off this section in low or very high flows. The Clarno unit of John Day Fossil Beds is beside the Clarno launch.

A Recreation.gov permit is required year-round to boat anywhere between Service Creek and Tumwater Falls, day or overnight, with a limited quota in the May 1 to July 15 high season. Groups are capped at 16 people, and high-season permits launched from Service Creek do not allow a take-out below Clarno. Twickenham's launch is on private land managed by ODFW and closes at times, so check the Prineville BLM page before you commit to a shuttle.

Smallmouth bass

Smallmouth are the reason most anglers float the John Day. ODFW calls it a world-class bass fishery, there is no bag or size limit on the river, and the season runs all year, with bass fishing lighting up once water temperatures pass 50 degrees in May and peaking from mid June through August. Steve Fleming of Mah-Hah Outfitters, the river's longest-running bass guide, fishes big fish in the cold water of March to mid May and numbers all summer; in July and August a popper on the surface or a crawfish streamer along the rock banks and eddy lines is all you need. Fish are thick from the mouth up past Kimberly.

Summer steelhead and redband trout

The John Day has one of the last entirely wild summer steelhead runs in the Columbia basin: no hatchery releases, so every fish you hook is wild and must be released, and only adipose-clipped strays may be kept. The run enters the river in fall, and the season, when open, is September 1 through April 30 from the mouth to the North Fork with prime fishing from late October into December. Because the run is managed under ODFW's John Day River Steelhead Framework, the fishery closes when the wild count at Bonneville Dam falls short; on September 1, 2026 ODFW closed all steelhead angling on the John Day and its forks through at least December 31, 2026. Check the ODFW Northeast Zone regulation updates before you plan a steelhead trip.

Native redband rainbow trout live in the cooler upper river and in the North and Middle Forks, not in the bass canyon; the mainstem below Kimberly is too warm in summer to hold trout. The older description of this as a cutthroat or redband dry fly canyon was wrong.

Season and regulations

This page compares USGS 14046500 John Day River at Service Creek, the gauge BLM and the outfitters use, against 300 to 5,000 cfs. BLM's recommended minimums are about 300 cfs for canoes and inflatable kayaks (lining Clarno Rapid), 1,000 cfs for rafts and 1,200 cfs for drift boats; Mah-Hah Outfitters fishes best on a stable or dropping river under 7,000 cfs and warns that Clarno Rapid is dangerous to boaters above 5,000 cfs, with BLM calling 5,500 to 7,500 cfs its hardest level. The river has no dams, so it spikes with snowmelt and rain in spring and can fall below 200 cfs by late summer, when even light rafts drag.

ODFW Northeast Zone: the mainstem from the railroad bridge at the mouth to the North Fork is open all year for bass, catfish and other warmwater fish with no bass limit, and bait is allowed. Trout in rivers and streams are open May 22 through October 31 with a two-fish, 8 inch limit. Hatchery steelhead only, January 1 to April 30 and September 1 to December 31, subject to in-season closures. Confirm the current Oregon Sport Fishing Regulations and the zone regulation updates before you go.
