Access map
Put-in
Eby's Mill AccessEby's Mill was rebuilt after earlier construction closures, but access status can still change after high water, grading, or road work.
Take-out
Supples Bridge Access / Temple Hill RoadSupples Bridge access sits downstream of the bridge on river right and is mostly sandy rather than a full-service ramp; confirm exit visibility from the road before launching.
Road shuttle
Stage Supples Bridge / Temple Hill Road first, then drive back to Eby's Mill. Most shuttle roads are paved, but verify the sandy downstream access and parking before leaving a vehicle.

More route and safety guidance

- Supples Bridge / Temple Hill Road is a legitimate but simpler sand access downstream of the bridge. Confirm bank condition and road parking before committing a shuttle.
