5,758-acre lake near Norrtälje. The lake tops out around 20 m. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Erken mäter 2 283 hektar bakom 56.2 km strandlinje, uppbruten av 15 öar. Strandlinjen är kraftigt flikig (index 3.3) — vikar och uddar överallt, vilket mångdubblar den fiskbara kanten. Cirka 58% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 10.6 km, som bredast 3.9 km. Vattnet hör till Norrtälje kommun. Närmaste kartlagda vatten är Långsjön, 3.2 km åt norr.
Gratis interaktiv fiskekarta — Erken, Sverige: ungefärliga djupkurvor ner till 20 m (66 fot), och de bästa fiskeplatserna för abborre, gädda, gös med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Come spring, look for european perch tight to the bank in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Start at Shallow bay flat. It's a weed flat holding about 2 m of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 2.5 to 8.5 m | dawn | Sharp break (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Break off the point (9 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (9 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Put Shallow bay flat first on the milk run — a weed flat near 2 m that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (2 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Sharp break (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Shallow bay flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (2 m) | Tip-ups, Large jigging spoon |
Come spring, look for zander tight to the bank in 1 to 4.5 m. Expect a summer slide to 4.5 to 11 m, then a winter hold in 6 to 12 m. Start at Break off the point. It's a drop-off holding about 9 m of water and rates prime come fall. Prime time lands in the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | Rock reef (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Break off the point (9 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Break off the point (9 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Break off the point (9 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Spring burbot on Erken hold shallow, usually 6 to 20 m. Depth-wise the year is flat: 6 to 20 m in summer, 4.5 to 18 m once it turns cold. Put Deep basin first on the milk run — a deep basin near 17 m that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
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 | 6 to 20 m chart-limited; documented 7.5 to 21 m | night & dusk | Deep basin (17 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 6 to 20 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (17 m) | Heavy jig + cut bait |
| Höst | 6 to 20 m chart-limited; documented 9 to 24 m | night & dusk | Deep basin (17 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Deep basin (17 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
In spring, roach run shallow here, mostly 0.5 to 3 m. Midsummer fish sit out in 1 to 5.5 m before dropping to 3.5 to 11 m for winter. Spring roach concentrate at Shallow bay flat, a prime-rated weed flat around 2 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a tiny spoon or a micro jig most summer days.

| Vinter | 3.5 to 11 m | midday | Break off the point (9 m) | Tungsten mormyshka |
Spring ruffe on Erken hold shallow, usually 1 to 4.5 m. By summer they slide out to 3 to 9 m, and by winter most fish are in 4.5 to 12 m. The chart's best answer is Feeding flat — feeding flat, 3.5 m, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a micro jig.
