Trip details

Access rules, camping and seasonal notes.

Permits, camping and season
PermitsNone notedNo route-specific paddling permit is known. Use the named public water-trail accesses, follow Wisconsin boating/PFD rules, and respect county, dam, and private-property postings.
CampingOptions nearbyTreat this as a day route. No designated on-route campsite is selected between Clarks Mills Dam and County Road S; use separate Manitowoc-area or state-forest camping only if independently reserved and current.
SeasonApr-OctSpring and rain-supported windows are most reliable. Summer can drop below the WRT floor, while storm water can quickly turn ledges, bridge approaches, and strainers into advanced whitewater hazards.

Access and shuttle

Launch below Clarks Mills Dam for the short ledgy upper-Manitowoc segment to County Road S. The reach is compact but not casual: Lower Cato Falls, boulder gardens, private banks, and water-quality issues after rain all need a conservative scout.

DirectionsOpen map

MRW lists the Clarks Mills site as a carry-in just below the dam with adjacent parking; do not launch upstream of the dam.

Finish

Take-out

County Road S / Manitowoc County Game Protection Site
DirectionsOpen map

Lower Cato Falls County Park provides public scouting access via steep stairs to the river. The available sources do not establish a bypass carry around the falls; do not launch unless every paddler is prepared to run the rapid safely.

Road shuttle

Stage the County Road S / Game Protection Site take-out first, then launch only from the carry-in below Clarks Mills Dam. Walk the take-out and scout Lower Cato Falls from Lower Cato Falls County Park before committing.

Clarks Mills Dam carry-in below dam to County Road S / Manitowoc County Game Protection Site is about 2.7 mi. Use the planner to compare shorter access pairs.

Additional access notes
  • County Road S / Game Protection Site is the selected take-out; verify parking and footing before launching because flows and mud can change access quality.
More route and safety guidance
  • Scout Lower Cato Falls from the public park before launching. The park's stair access reaches the river but does not establish a bypass carry; do not launch unless every paddler is prepared to run the rapid safely.
  • Expect fast current, boulder gardens, strainers, manure-runoff water-quality concerns after rain, private banks, and limited legal bailout choices.
