How this map was made
Real DNR depth soundings drape over USGS 3DEP elevation, with a USDA NAIP aerial basemap and OpenStreetMap shoreline. Colour shows surveyed depth; dark lines are the survey's own isobaths.

Stocking: Over the last 40 years, Heron Lake has been surveyed eight times to assess the fish community (1988, 1996, 2004, and 2018) and evaluate stocking efforts (1989, 1991, 1996, and 1997).
Length is the largest fish netted in the survey, not an angler record. Source: Michigan DNR Status of the Fishery Resource report (counts summed across survey years).
