5,882-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.
Tyräjärvi maps at 6,018 acres behind 33.6 miles of shoreline. A development index of 3.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 72% of the water is 15 ft or less, the band where the food chain lives.

Spring european perch on Tyräjärvi hold shallow, usually 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).

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

When the water first warms, northern pike slide up into 2 to 8 ft. Summer is a 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
