----Loading--
DifficultymoderateThe reach has no major rapids in DNR’s water-trail description, but it is about 11 miles, has fewer formal exits than the upstream connectors, and depends on clean wood and suitable water before reaching the state-park finish.
PermitsNone notedNo route-specific paddling permit is known. Follow Minnesota boating/PFD rules and obey all Flandrau State Park permits, camping reservations, watercraft-campsite rules, and posted closures.
CampingOptions nearbyFlandrau State Park is the selected overnight support. MN DNR Map 4 shows park camping, water, toilets, and a watercraft campsite at river mile 5.7; use designated sites only and confirm current park availability before counting on an overnight.
SeasonApr-OctSpring and rain-fed windows are most reliable. The lower Cottonwood can become scrape-prone in summer lows and reacts quickly to storm runoff, so use the interpreted band with launch-site inspection.

Access, shuttle, and map

Access caveats and watch for

Access caveats

  • MN DNR Map 4 places County Road 11 at river mile 16.8 and Flandrau State Park camping/access context from river mile 6.5 to 4.0, with a watercraft campsite at river mile 5.7.
  • Minnesota public-water-access GIS resolves County Road 11 as WAS01424 and Flandrau State Park as WAS02651; the Flandrau access lists carry-in launch, parking, and restroom context.
  • The New Ulm DNR gauge is downstream near the lower Cottonwood corridor. Use it as the closest official interpreted lower-river check, then verify depth and access footing at County Road 11 and Flandrau.

Watch for

  • Scrapable low water when the New Ulm gauge is below 150 cfs, plus shallow bars and possible dragging before the park.
  • Strainers, fresh wood, muddy banks, private shoreland, and fast rises after thunderstorms.
  • State-park rule changes, campsite availability, high-water closures, and limited legal bailout options before the Flandrau access.
