Route overview

Quick facts and what's next

Distance, difficulty, shuttle basics, and the near-term outlook before you commit to the drive.

Quick facts

On-water distanceAbout 1.8 miLake Carlos State Park to Highway 29
DifficultymoderateMileage is short, but the Lake Carlos outlet, constructed rock rapids with portage right, low bridges and culverts, and downstream proxy gauge make it a planning route rather than a casual park loop.
ShuttleCar shuttleStage Highway 29 first, then launch from the Lake Carlos State Park access. Confirm state-park parking rules, outlet depth, the portage-right route, and the Highway 29 landing before loading boats.
PermitsNone notedNo route-specific paddling permit is known. A state-park vehicle permit may be required at Lake Carlos State Park. Follow posted park, DNR public-access, boating, and PFD rules.
CampingOptions nearbyLake Carlos State Park has campground support at the put-in, but this short route has no assumed on-route campsite. Treat camping as endpoint basecamp only under current state-park rules.
SeasonApr-SepDNR says the Long Prairie is usually best in spring and early summer, while some portions become slow, shallow, or impassable in summer. The headwaters route needs a fresh outlet and portage check even when the downstream gauge is acceptable.

Access caveats and watch for

Access caveats

  • DNR Map Long Prairie places Lake Carlos State Park and the lake outlet at river mile 93.7, constructed rock rapids at 93.4, and the Highway 29 carry-in near river mile 91.9.
  • Public-water-access GIS resolves Lake Carlos State Park and Highway 29 with coordinates; Highway 29's public-access river mile is listed as 91.0, so use the mapped access and coordinates rather than mileage alone.
  • The Long Prairie gauge is far downstream in town and should not replace same-day checks at the Lake Carlos outlet and Highway 29 landing.

Watch for

  • Constructed rock rapids below Lake Carlos State Park with portage right.
  • Low water, slow shallow channels, low bridges and culverts, strainers, and private banks.
  • State-park rules, parking/vehicle permits, and lake wind at the put-in.
