Fishing Mille Lacs Lake: what the data says
132,000-acre walleye and trophy smallmouth lake with famous rock and gravel structure. The lake tops out around 40 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
Walleye fishing at Mille Lacs Lake
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft.
