Quad-culvert -- ~1/8th Mile!

The river enters four ~7-8' diameter culverts for ~656'. A right-bend midway through means you won't see 'the light at the end of the tunnel' (until after that bend)!

Nearly a mile of heavily wooded banks upstream are very subject to deadfall, so wood accumulates here, hanging surprisingly high on these culverts, potentially precluding entering ANY of the culverts. The county (or some entity) occasionally clears wood from this location. However, it would be possible for wood to hang up within them, making entering any of them (in a boat) an extremely risky proposition. Even if passage were possible, each boater would need a bright water-resistant flashlight/headlamp to navigate the tunnels! Also, it would be nearly mandatory (before entering the tunnels) to go ashore and walk to the end of the culverts to scout there. (See next description for more info on that.)

This is scheduled to be 'daylighted' (removal of culverts). MMSD website says "Construction on the riverbed is expected to begin in 2026"

Until that happens, significant skills may be needed to get ashore (in the cement trough prior to the culverts), to exit your boat, and to portage (bushwhacking through the woods) to the downstream end of the culverts.
