OpenStreetMap shows about 3.7 mi of public hiking and walking trail within about 100 m (330 ft) of the Flour Lake shoreline, mostly along the east and west shores.
No trailhead is mapped for these trails. The closest public access site is Flour Lake Public Water Access Site, 0.2 mi 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.
We found 43 campgrounds and RV parks within 15 miles of Flour Lake, 19 of them within 5 miles. 2 are right on the shore. Distances are straight-line from the nearest point on the shoreline, so driving distance is longer.

Live from the National Weather Service API for the lake's coordinates (48.0518, -90.3654). The nearest station may be several miles away. NWS forecast for Flour Lake. No live water-temperature sensor is shown because we haven't found a public one for this lake.
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.
