Fishing Kotojärvi: what the data says
261-acre lake in Finland. The lake tops out around 33 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. What the data behind the map says about each species, season by season:
Traced from the shoreline, Kotojärvi runs 259 acres with 5.9 miles of edge. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 72% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.
