Au Sable River

These links were checked against the live agency site on 2026-09-01. Rules for a water change inside a season, so the agency’s own page on the day you go is the only current answer — this desk does not hold one.

No unique fleet-directory record matched this operational water by name and state, so the desk will not borrow another water’s review date. The agency links on this page were checked on 2026-09-01; check the agency’s own page the day you go.

Freestone reaches on this list are generally reached from a road that runs the valley — bridge crossings, pullouts and public-land frontage. Between those, ownership changes without a sign.

Launch · Hand-launch for a raft or small drift boat at bridges and pullouts where it is legal. Confirm the take-out before you push off; a freestone take-out can be a long way down.

Parking · Parking is at designated access points. A pullout that looks fine is not automatically legal or safe to leave a vehicle in.

Michigan publishes a boat launch locator; a Recreation Passport is normally required for state-managed launches.

Flow and water temperature for this water are read from USGS site 04136000, Au Sable River near Red Oak, MI. It is an official public gauge, not a fishing pin: it describes the river at one point, and the reach you stand in may be doing something else.

Derived from water class (freestone) and Midwest range — not a stocking record. Confirm species, seasons and any closures with Michigan Department of Natural Resources.
