Fishing Käärmejärvi: what the data says
352-acre lake in Finland. The lake tops out around 5 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's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Käärmejärvi runs 350 acres with 4.8 miles of edge. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end.
