Rating depth structure for northern pike.
Recent public catches load as you reach this section.
13-acre lake in Sweden. The lake tops out around 3.5 m. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
Vattnet ritar ut 5 hektar med 1 km strand. Med index 1.3 är formen nära cirkelrund: läs botten, inte strandlinjen. Hela sjön är grundare än ~5 m — vegetation och betesfisk från strand till strand. Räkna med 0.5 km vatten från ena änden till den andra. Sjön ligger i Ale kommun. Osjön ligger 1.6 km åt sydväst — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Björsjön, 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.
The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. Midsummer fish sit out in 1 to 3.5 m before dropping to 1 to 3.5 m for winter. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
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 |
Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. They don't go far with the seasons — 1 to 3.5 m covers summer, 1 to 3.5 m covers winter. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for european perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.

| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| 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 |
When the water first warms, brown trout slide up into 0.5 to 3.5 m. There's no big seasonal slide here — summer means 1 to 3.5 m, winter 0.5 to 3.5 m. If you only fish one area, make it Shoreline break: a drop-off around 1.5 m that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.

Anglers target northern pike, european perch, brown trout on Björsjön. 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. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Björsjön is regulated by the Svenska Fiskeregler (official Swedish rules service). Check the official Sweden regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
