Depth FAQ

How deep is Duck Lake?

Duck Lake has surveyed depth contours down to 20 feet, but no separately verified maximum depth is on record yet.

Is there a free depth map of Duck Lake?

Yes. LakeList publishes a free interactive depth contour map of Duck Lake at a typical 10-foot interval, with an optional 3D underwater view, derived from Minnesota DNR survey data.

Where does the Duck Lake depth map come from?

The interactive depth contours are derived from Minnesota DNR. Each contour set passes a visual QA review against the source document before it is published. The depths are from an official Minnesota DNR survey (measured bathymetric contours); not for navigation.
