Fishing Haapajärvi: what the data says
1,772-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 follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Haapajärvi runs 1,796 acres with 29.1 miles of edge. A development index of 4.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 95% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.
