22,931-acre lake near Karlsborg. The lake tops out around 102 m. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
Vattnet ritar ut 9 351 hektar med 102.8 km strand, uppbruten av 18 öar. Ett strandindex på 3 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 18% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 20 km vatten från ena änden till den andra och 10.8 km på bredden. Sjön ligger i Karlsborg kommun. Sänningen ligger 6.4 km åt väster — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Unden, Sverige: ungefärliga djupkurvor ner till 102 m (335 fot), och de bästa fiskeplatserna för abborre, gädda, lake 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: european perch in 1 to 3.5 m. Midsummer fish sit out in 2.5 to 8.5 m before dropping to 3.5 to 10 m for winter. The spot to know is Shallow bay flat, a feeding flat in about 2 m of water that rates prime for european perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) gets it done.
| 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 | Offshore hump (7.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Offshore hump (7.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Offshore hump (7.5 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 0.5 to 2.5 m that time of year. Summer pushes them deeper, 2.5 to 6 m, and winter fish settle into 1.5 to 4.5 m. The spot to know is Creek inflow, an inflow / creek mouth in about 2.5 m of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Creek inflow (2.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Shallow bay flat (2 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 |
Spring puts burbot in skinny water — 7.5 to 21 m is the zone. As the season builds they drop to 15 to 37 m, wintering in 4.5 to 18 m. Winter burbot concentrate at Offshore hump, a prime-rated offshore hump around 7.5 m. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Offshore hump (7.5 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Deep basin (87 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Offshore hump (10 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Offshore hump (7.5 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Early season arctic char use the shallows, holding in 1 to 4.5 m. Expect a summer slide to 6 to 18 m, then a winter hold in 3 to 12 m. Put Offshore hump first on the milk run — an offshore hump near 7.5 m that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a jigging spoon vertical or a tube jig (smelt) and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | midday & dawn | Creek inflow (2.5 m) | Small casting spoon (silver/orange), Jerkbait (small) |
| Sommar | 6 to 18 m | dawn | Offshore hump (7.5 m) | Jigging spoon vertical, Tube jig (smelt) |

| Vinter | 3 to 12 m | midday & dawn | Offshore hump (7.5 m) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Early season lake whitefish use the shallows, holding in 4.5 to 14 m. Expect a summer slide to 12 to 27 m, then a winter hold in 7.5 to 21 m. Put Rock reef first on the milk run — a rock pile near 2 m that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Offshore hump (7.5 m) | Small jig + waxworm, Blade bait (small) |
