Sauk Lake (S) is a concrete boat ramp access point located on the south shore of Sauk Lake in Stearns County, administered by the City of Sauk Centre.

This public water access site is one of three launches available on Sauk Lake and provides a convenient entry point for boaters and paddlers accessing the 2,126-acre lake.

Note that Sauk Lake contains aquatic invasive species including zebra mussels and flowering rush, so watercraft must be cleaned and drained before and after use.
