Safety

CautionThis route has hazards or access considerations that require extra verification.
Safety details
Launch only at the mapped Frogtown Park carry-in below the Cold Spring Dam and finish at Rockville County Park. Do not improvise a put-in upstream of the dam.
- MN DNR warns that snags and fallen trees can tip an unwary paddler. Use the official 15 to 17 ft St. Martin band as level context, not a wood-clearance guarantee, and reassess when the river is rising.
- Use the named public accesses and designated stops because MN DNR says much of the Sauk shoreline is private.

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 lower-Sauk zone. Below 14 ft the river trends scrape-prone and weedy, while flood-style caution starts to matter above 20 ft.

Access caveats and watch for
Access caveats
- Frogtown Park is the mapped carry-in 0.2 river mile below Cold Spring Dam. Start at that downstream landing and do not improvise a put-in upstream of the dam.
- Rockville County Park has posted hours and county rules that still deserve a same-day check before you leave a shuttle vehicle.
Watch for
- Snags, fallen trees, and overhanging or dead trees; the normal gauge band does not guarantee a clear channel.
- Scrapier water and slower progress when the St. Martin gauge falls toward 14 ft.
- Changing or rising river conditions; reassess rather than relying on an earlier gauge check.
- Private shoreline; stop only at the named public accesses or other designated sites.
