Rating depth structure for northern pike.
Recent public catches load as you reach this section.
21-acre lake in Sweden. The lake tops out around 3.5 m. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
Bysjön mäter 8 hektar bakom 1.3 km strandlinje. Bassängen är enkel (strandindex 1.2) — nästan en skål, så djupkurvorna betyder mer än stranden. Inget här går djupare än ~5 m: en enda stor grundzon med föda och skydd. Från ände till ände mäter vattnet ungefär 0.5 km, som bredast 0.3 km. Vattnet hör till Alingsås kommun. Närmaste kartlagda vatten är Rydbosjön, 0 km åt öster.
Gratis interaktiv fiskekarta — Bysjön, Sverige: ungefärliga djupkurvor ner till 3 m (11 fot), och de bästa fiskeplatserna för gädda, abborre och öring. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Come spring, look for northern pike tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 1 to 3.5 m, then a winter hold in 1 to 3.5 m. Start at Shallow bay flat. It's a weed flat holding about 1 m of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 1 to 3.5 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Shallow bay flat (1 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 1 to 3.5 m chart-limited; documented 2 to 5.5 m | midday & dawn | Shallow bay flat (1 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1 to 3.5 m chart-limited; documented 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
Early season european perch use the shallows, holding in 1 to 3.5 m. Even in summer they hold at 1 to 3.5 m; winter keeps them in 1 to 3.5 m. Put Shallow bay flat first on the milk run — a weed flat near 1 m that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.

|---|---|---|---|---|
| Vår | 1 to 3.5 m chart-limited; documented 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 1 to 3.5 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (2.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 1 to 3.5 m chart-limited; documented 3 to 10 m | midday | Deep basin (2.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 1 to 3.5 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (2.5 m) | Tungsten jig + maggots, Small balance jig |
Spring puts brown trout in skinny water — 0.5 to 3.5 m is the zone. Summer fish stay in 1 to 3.5 m, and winter fish hold in 0.5 to 3.5 m. Summer brown trout concentrate at Shoreline break, a prime-rated drop-off around 1.5 m. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.

Anglers target northern pike, european perch, brown trout on Bysjön. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for northern pike in spring. Scroll up to the map for the complete spot list by species and season.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
