Fishing Herajärvi: what the data says
485-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.
The drawn water covers 525 acres wrapped in 5 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 59% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.

European Perch fishing at Herajärvi
Come spring, look for european perch tight to the bank in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 12 to 33 ft. Start at Back-bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Inline spinner #1-2 |

Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
