Fishing Suuri Siikajärvi: what the data says
395-acre lake in Finland. The lake tops out around 148 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. Species by species, here's what the data says the year looks like.
