608-acre lake near Björklinge. The lake tops out around 12 m. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What the data behind the map says about each species, season by season:
Vattnet ritar ut 243 hektar med 11.3 km strand. Strandlinjen är måttligt strukturerad (index 2) — tillräckligt med uddar och vikar att fiska av. Ungefär 65% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 4.5 km vatten från ena änden till den andra och 1.3 km på bredden. Sjön ligger i Uppsala kommun. Ramsjön ligger 8 km åt nordväst — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Långsjön, Sverige: ungefärliga djupkurvor ner till 12 m (41 fot), och de bästa fiskeplatserna för abborre och gädda. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Spring puts european perch in skinny water — 1 to 3.5 m is the zone. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Shallow bay flat is the standout, a weed flat at roughly 1.5 m, 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.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (1.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 2.5 to 8.5 m | dawn | Break off the point (5.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Deep basin (11 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Deep basin (11 m) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1.5 m. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Break off the point (5.5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Break off the point (5.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (1.5 m) | Tip-ups, Large jigging spoon |
When the water first warms, roach slide up into 0.5 to 3 m. By summer they slide out to 1 to 5.5 m, and by winter most fish are in 3.5 to 11 m. If you only fish one area, make it Shallow bay flat: a weed flat around 1.5 m that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a tiny spoon or a micro jig rigged through the warm months.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Shallow bay flat (1.5 m) | Micro jig under a float |
| Sommar | 1 to 5.5 m | dawn & dusk | Shallow bay flat (1.5 m) | Tiny spoon, Micro jig |
| Höst | 2.5 to 8.5 m | midday | Break off the point (5.5 m) | Tiny jig, Small silver spoon |
| Vinter | 3.5 to 11 m | midday | Deep basin (11 m) | Tungsten mormyshka |
Early season rudd use the shallows, holding in 0.5 to 2.5 m. Expect a summer slide to 0.5 to 3.5 m, then a winter hold in 3.5 to 9 m. Put Shallow bay flat first on the milk run — a weed flat near 1.5 m that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a tiny surface fly or a micro spoon and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dusk | Shallow bay flat (1.5 m) | Micro jig, Tiny dry fly |
| Sommar | 0.5 to 3.5 m | dawn & dusk | Shallow bay flat (1.5 m) | Tiny surface fly, Micro spoon |
| Höst | 1.5 to 5.5 m | midday | Break off the point (5.5 m) | Micro jig |
| Vinter | 3.5 to 9 m | midday | Deep basin (11 m) | Tiny mormyshka |

Shallow bay flat is the top-rated area: a weed flat in about 5 ft of water that rates prime for european perch in spring. The interactive chart above rates every spot for each species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
