About Little Illinois River Falls

Little Illinois River Falls is a set of cataracts where the Illinois River narrows at a bend, at the western end of the river's Wild and Scenic section in the Rogue River-Siskiyou National Forest near Kerby. The drops are low, and at very high water they are nearly drowned out. A one-mile loop from the Little Falls Trailhead on Eight Dollar Mountain Road leads down to a rocky bluff above the falls, in the Eight Dollar Mountain Botanical Area known for spring wildflowers.

The Setting

Little Illinois River Falls sits at 1,198 feet within Siskiyou National Forest, fed by the Illinois River, in the foothills of Oregon.

Trail Description

From the Little Falls Trailhead, a loop of about one mile drops to the Illinois River, switchbacking down a rubbly trail to a rocky bluff above the cataracts, then climbs back to a miner's ditch and the trailhead. A short scramble reaches riverside boulders for a closer view. A longer 3.8-mile option starts at the Jeffrey Pine Trailhead and follows the Little Falls Trail along an old mining ditch.

How we calculate this

This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Weather Forecast

The Terrain, Seen by LiDAR

Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.

The bare-earth surface loses about 86 feet through the falls, but gradually, the profile of a cascade rather than a plunge. The ground at the falls is roughly 1,182 feet above sea level.

The whole reach is steep: about 70 feet of descent in the 500 feet above the falls and another 133 feet in the 500 feet below. The falls face west and glow in afternoon and evening light.
