Johnsrud Park to Weigh Station
GO Running well at 593 CFS. · Conditions as of Oct 18, 2026, 11:30 PM. Printed snapshot generated Oct 19, 2026, 12:35 AM— conditions change, wood moves, levels swing. Verify the gauge and scout anything you can't read from upstream.
The run
Missoula's summer float — the mellow lower canyon from the Johnsrud beach scene down to Bonner. Easy Class I-II water that becomes the region's tubing mecca as flows drop.
Getting there & back
Put-in
Johnsrud Park — The largest site on the river and the downstream end of the Recreation Corridor — concrete ramp, drinking water, toilets, and a reservable group picnic shelter (406-542-5500). Day use; closed in winter. On hot summer days it is a full-on beach scene, and the take-out gets very busy.
Take-out
Weigh Station — Concrete ramp and vault toilet half a mile east of Bonner — the last reliable take-out on the river. The short reach below, down to the I-90 bridges, was temporarily closed to all use in August 2025 for BNSF railroad-bridge repairs and that work is expected to resume mid-summer 2026; check FWP's current closures before planning to continue toward Milltown.
Shuttle (take-out → put-in): 10.4 mi · ≈ 13 min
