662-acre lake near Alger County. The lake tops out around 10 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. Below is the species-by-species picture, pulled from the same data the map uses.
Sixteenmile Lake maps at 598 acres behind 5.8 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze.
