Safety

CautionThis route has hazards or access considerations that require extra verification.
Safety details
MN DNR maps nearly continuous boulder-filled Class I-II rapids and scattered surfing waves in the final 2.5 miles above Heims Mill; this late section requires moving-water boat control after a long approach.
- Use the official 15 to 17 ft St. Martin band as level context, not clearance to run the rapids. Low water may make them impassable, while very high water is dangerous and not recommended.
- Watch for snags and fallen trees, especially where current narrows your options. Use the named Rockville County Park and Heims Mill carry-ins and stop only at designated public sites because much of the shoreline is private.

Gauge note
Target band: 15.00 ft to 17.00 ft · Sauk River nr St. Martin, CR12
Gauge context
Treat 15 to 17 ft at St. Martin as the best all-around range. Below 14 ft the lower river gets scrape-prone and the mouth rapids can turn bony, while above 20 ft the finish becomes substantially more consequential.

Access caveats and watch for
Access caveats
- Rockville County Park has posted hours, drinking water, and a watercraft campsite, but local rules still override any stale assumptions when you arrive.
- Heims Mill is a managed carry-in with restroom and picnic amenities, not a broad paved ramp or a place to sort out a casual shuttle plan.
- Because the route is long and the technical section comes late, it is worth scouting the take-out before you launch.
Watch for
- Vegetation, shallow stretches, and extra drag when the St. Martin gauge trends toward 14 ft.
- Boulder-filled Class I-II rapids in the final 2.5 miles, especially at lower water.
- Snags and fallen trees where current narrows your options near the Mississippi confluence.
- Private shoreline outside designated public accesses and campsites.
- Fatigue on a 16.8-mile route whose technical section comes at the end.
