Fishing Ala-Ruokonen: what the data says
768-acre lake in Finland. The lake tops out around 66 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 follows comes from the same scoring engine that paints the spots above.
The drawn water covers 772 acres wrapped in 7.1 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. 39% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.
