12-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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Pitkä Helvetinjärvi runs 12 acres with 1 miles of edge. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Roughly 76% 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. Fall european perch concentrate at Deep basin, a prime-rated deep basin around 29 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
