Access rules, camping and seasonal notes.

Permits, camping and season
PermitsNone notedNo route-specific paddling permit is known. Use the DNR public accesses, follow Minnesota boating/PFD rules, and check current St. Louis River water-trail alerts.
CampingDay tripTreat this as a day trip. No designated on-route campsite was verified between Forbes and Zim; use only separately confirmed public or private campground options off route.
SeasonMay-SepDNR says upper St. Louis flow usually peaks in late April and falls through summer. Rain can quickly change the shallow boulder and wood picture, while low summer readings can mean dragging.

Access and shuttle

Launch at the Forbes DNR public access and take out at Zim for the missing upper-St. Louis connector between the County-Road-95-to-Forbes and Zim-to-Toivola cards. The route uses the direct Forbes DNR gauge and carries low-water, dam, cold-water, and remote-rescue caveats.

DirectionsOpen map

Zim resolves in Minnesota public-water-access GIS as WAS00613 near DNR river mile 113.0.

Road shuttle

Stage Zim first, then drive back to Forbes. Check the Forbes DNR gauge and walk both carry-in accesses before launching because the current run-start reading was below the official scrapable floor.

Additional access notes
  • Keep the trip framed from public access to public access. Do not use private banks or dam infrastructure for routine stops.
More route and safety guidance
  • DNR flags the Forbes gauge corridor for Class I-II maneuvering and dam portage skills. Low water exposes rocks; rising water shortens reaction time around wood and bends.
  • Use the named DNR public accesses only. This is a remote cold-water section with limited exits, private banks, and long rescue spacing.
