Safety
Route safety
CautionThis route has hazards or access considerations that require extra verification.
Missouri State Parks identifies separate signed canoe and boat launches around the Onondaga River bridge; use the launch that matches the craft and current park rules rather than an informal bank path.
Safety details
- MDC planning material identifies Onondaga Cave State Park to Campbell Bridge as a five-mile canoe float, and Campbell Bridge has a concrete ramp, canoe launch, restroom, and parking. Verify the Campbell landing from the road before launching.
- Keep the 200 cfs floor as a conservative low-water check. High or rising water can add fresh wood, bridge current, faster bends, and harder landings; do not use private banks or gravel bars as substitute access.
