703-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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Ihalanjärvi runs 739 acres with 10.1 miles of edge. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 49% of the water is 15 ft or less, the band where the food chain lives.

Spring puts european perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 28 ft, wintering in 12 to 33 ft. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
