Fishing Pirttijärvi-Riihijärvi: what the data says
384-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 387 acres wrapped in 9.1 miles of bank. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. 46% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.
