Rating depth structure for northern pike.
Recent public catches load as you reach this section.
4,721-acre lake in Sweden. The lake tops out around 64 m. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Järnsjön mäter 1 906 hektar bakom 31.2 km strandlinje. Strandlinjen är måttligt strukturerad (index 2) — tillräckligt med uddar och vikar att fiska av. Ungefär 6% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 8.2 km vatten från ena änden till den andra och 5.5 km på bredden. Sjön ligger i Årjäng kommun. Långtjärn ligger 1.6 km åt sydost — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Järnsjön, Sverige: ungefärliga djupkurvor ner till 64 m (211 fot), och de bästa fiskeplatserna för gädda, abborre, öring med flera. 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 2.5 to 6 m before dropping to 1.5 to 4.5 m for winter. The spot to know is Shallow bay flat, a feeding flat in about 2 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.
| 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 | Shoreline point (5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Shoreline point (5 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 |
Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. The spot to know is Sharp break, a drop-off in about 8.5 m of water that rates prime for european perch in summer. 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 | 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 (8.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Sharp break (8.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Offshore hump (6 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, brown trout slide up into 1 to 7.5 m. By summer they slide out to 7.5 to 18 m, and by winter most fish are in 1.5 to 11 m. If you only fish one area, make it Sharp break: a drop-off around 16 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.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Shoreline point (5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Sharp break (16 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Shoreline point (5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Sharp break (8.5 m) | Jigging spoon, Small stickbait (slow) |
Spring lake whitefish on Järnsjön hold shallow, usually 4.5 to 14 m. They move out to 12 to 27 m in summer and finish the year down in 7.5 to 21 m. Put Offshore hump first on the milk run — an offshore hump near 6 m that grades prime for spring. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Offshore hump (6 m) | Small jig + waxworm, Blade bait (small) |
| Sommar | 12 to 27 m | dawn | Sharp break (16 m) | Blade bait vertical, Small jigging spoon |
| Höst | 2.5 to 9 m | dusk | Offshore hump (6 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Sharp break (16 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, burbot run shallow here, mostly 7.5 to 21 m. Midsummer fish sit out in 15 to 37 m before dropping to 4.5 to 18 m for winter. Winter burbot concentrate at Offshore hump, a prime-rated offshore hump around 6 m. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Sharp break (16 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Break off the point (29 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Sharp break (16 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Offshore hump (6 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Järnsjön carries 10 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 55 m down.
Season dates, license requirements, and size and bag limits for Sweden waters are set by the Svenska Fiskeregler (official Swedish rules service) — and special regulations can apply to Järnsjön specifically, so confirm the current rules before you fish.

Järnsjön is about 211 ft (64 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.

Anglers target northern pike, european perch, brown trout, lake whitefish, burbot on Järnsjön. 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.
Offshore hump is the top-rated area: an offshore hump in about 20 ft of water that rates prime for burbot in winter. Open the map above to see every rated spot for each 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.
Fishing on Järnsjön 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.
