31-acre lake in Sweden. The lake tops out around 31 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Långsjön runs 31 acres with 0.9 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 64% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

|---|---|---|---|---|

Spring puts european perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 9 to 31 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.

Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 9 to 31 ft game here, winter a 4 to 31 ft one. The chart's best answer is Break off the point — drop-off, 14 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 31 ft | night & dawn | Break off the point (14 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |

When the water first warms, lake whitefish slide up into 9 to 31 ft. The depth story barely changes: 9 to 31 ft through summer, 9 to 31 ft in winter. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

|---|---|---|---|---|
| Spring | 9 to 31 ft | midday & dawn | Break off the point (14 ft) | Small jig + waxworm, Blade bait (small) |
