Watch for

  • Non-native/invasive species. Zebra mussel and Curly-leaf pondweed recorded. Clean, drain and dry your boat and gear.

Trails along the shore

Getting to the trails

No trailhead is mapped for these trails. The closest public access site is Big Stone Lake, Bonanza Public Water Access Site, 50 ft from a shoreline trail (Minnesota DNR water access data).

The dashed brown line on the lake map shows these trails. We include paths, footways and marked trails that OpenStreetMap doesn't mark as private, and leave out roads, sidewalks and snowmobile corridors. Mapped trails can still cross private land or close for the season, and not every trail is mapped, so follow posted signs.

Trails: © OpenStreetMap contributors, available under the Open Database License (ODbL). Map data as of Oct 9, 2026. Trail lengths count only the parts within about 100 m of the USGS NHD lake outline.

Sun, moon & best fishing times

Sun & moon at Big Stone Lake

Best fishing times

Major periodMinor periodDaylight

    Based on solunar theory, an estimate. Major periods (about 2 hours) center on when the moon is directly overhead or underfoot; minor periods (about 1 hour) center on moonrise and moonset. The 0–100 activity score rises during those periods and gets a boost near sunrise and sunset and around the new and full moon. Weather, water temperature and pressure often matter more. Sun and moon times are calculated in your browser from the lake's coordinates with standard astronomy formulas, shown in CT (America/Chicago), and accurate to within a few minutes.
