337-acre lake in Finland. The lake tops out around 49 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.
Ehronjärvi maps at 335 acres behind 5 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. 45% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.

Spring european perch on Ehronjärvi hold shallow, usually 3 to 12 ft. By summer they slide out to 8 to 28 ft, and by winter most fish are in 12 to 33 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).

Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
