Divers Hole Day Use (USFS Rogue River-Siskiyou NF), Josephine County, OR

Eight and a half miles west of Selma, on the Illinois River Road, the Illinois River widens out and forms a deep pool. Shallow terraces surround it and lead down to a beach. The Forest Service names this stop Divers Hole Day Use and lists two things to do here, swimming and picnicking. By the agency’s account, the depth of the pool, its nearness to the main road, and the terraces around it make the beach easy to reach.

Nothing has been built at the site. There is no toilet, no drinking water, no picnic table, no fire pit, and no garbage service. Visitors are asked to pack out their trash. No fee is charged, and the site is open for day use from sunrise to sunset. The road is narrow in many places and has little room to park or pull off. For the corridor as a whole, the Forest Service asks drivers to park outside the white line, especially in the busy summer months, so that other vehicles, including emergency vehicles, can get through.

The Wild Rivers Ranger District at Cave Junction manages the site. Its seasonal order bans possessing alcohol along the recreational section of the river, within a quarter mile of each side of Forest Road 4103, and Divers Hole is one of the sites listed in it. The ban ran from May 22 through September 30, 2026. The same order, signed at Medford on May 11, 2026, covers May 28 through September 30, 2027.

Emerald water over serpentine

The Forest Service calls the Illinois’s water emerald green and says the river is a popular place to swim during the summer months. The federal rivers registry describes the water as blue-green and clear enough to see 15 feet down or more. It says thousands of people come to the river’s scenic section on hot summer days to get into that water.

The corridor around the pool is a landscape of serpentine rock and Jeffrey pine. Some of the plants growing here are rare adaptations to the serpentine. One is the California lady’s slipper, an orchid that can carry up to 21 flowers on a single stem; insects that enter its pouch are trapped there and fertilize it. The registry also lists Tolmie’s star tulip, rock cress, Kalmiopsis leachiana, Indian rhubarb, wild iris, butterwort, pitcher plant, Indian paintbrush, lupine, phlox, monkeyflower, and camas.

The canyon below the road

Below the road the river turns remote. Its Wild Section runs nearly 29 miles through steep canyons between Briggs Creek and Nancy Creek, with 150 rapids. Eleven are Class IV, and one is Class V, which Wikipedia names as Green Wall. The Forest Service calls this stretch one of the most inaccessible sections of wild river in the country. The Illinois River Trail runs for 27 miles somewhat near the water but never reaches the bank.

No dam controls the Illinois, so its flow depends on the weather, and water levels can rise fast. In March 1998 a flash flood killed two rafters, and ten others had to be rescued by helicopter. The sources disagree on when the river is usually run. The rivers registry gives the main boating season as March through mid-May. A paddlers’ guide cited on Wikipedia gives the rainy season, October through April. The river reaches the Rogue from the south at Agness, 27 miles from the Pacific.

Miners from Illinois, and an act of Congress

According to Oregon Geographic Names, the river takes its name from the state of Illinois, birthplace of three brothers named Althouse. The brothers came to Oregon and mined gold along Althouse Creek and the Illinois River. Miners from the same state named Sucker Creek, a tributary, after the Sucker State, one of Illinois’s nicknames.

On October 19, 1984, Congress added the Illinois to the National Wild and Scenic River System, from the national forest boundary downstream to the Rogue. The designated stretch is 50.4 miles long: 28.7 miles classed as wild, 17.9 as scenic, and 3.8 as recreational. Congress cited the river’s fisheries, water quality, scenery, recreation, and botanical values.

The fishery explains much of that list. Coho and chinook salmon, winter steelhead, cutthroat trout, Pacific lamprey, and green sturgeon all use the river. In the 1970s, sport anglers caught about 25,000 salmon and steelhead here each year, and the Illinois added another 85,000 salmon a year to the offshore commercial catch. Those numbers have since declined, as they have on every West Coast river. The Illinois is one of the few West Coast rivers with no hatchery program. Its salmon are wild, and they still leap natural barriers on the way back to the grounds where they were spawned, to reproduce and die there.
