1,707-acre lake near Munkedal. The lake tops out around 41 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. What the data behind the map says about each species, season by season:
Kärnsjön mäter 706 hektar bakom 35.1 km strandlinje, uppbruten av 2 öar. Ett strandindex på 3.7 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 38% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 9.3 km vatten från ena änden till den andra och 2.3 km på bredden. Sjön ligger i Munkedal kommun. Heevattnet ligger 3.2 km åt sydväst — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Kärnsjön, Sverige: ungefärliga djupkurvor ner till 41 m (133 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.
In spring, european perch run shallow here, mostly 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. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 2 m. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| 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 | Shallow bay flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 0.5 to 2.5 m. Summer pushes them deeper, 2.5 to 6 m, and winter fish settle into 1.5 to 4.5 m. Shallow bay flat is the standout, a weed flat at roughly 2 m, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| 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 | 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 |
In spring, zander run shallow here, mostly 1 to 4.5 m. Midsummer fish sit out in 4.5 to 11 m before dropping to 6 to 12 m for winter. Spring zander concentrate at Örekilsälven inflow, a prime-rated inflow / creek mouth around 2.5 m. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a vertical softbait over humps or a deep crankbait most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | Örekilsälven inflow (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Main-lake point (10 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Main-lake point (10 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Main-lake point (10 m) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: burbot in 7.5 to 21 m. As the season builds they drop to 15 to 37 m, wintering in 4.5 to 18 m. Top water on the chart: Deep basin, a deep basin in the 34 m range, prime in summer. Time it for after dark and midday. Summer baits: a heavy jig + cut bait gets it done.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Break off the point (18 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Deep basin (34 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Break off the point (18 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Break off the point (18 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Come spring, look for roach tight to the bank in 0.5 to 3 m. Expect a summer slide to 1 to 5.5 m, then a winter hold in 3.5 to 11 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 and the evening. A tiny spoon or a micro jig is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Shallow bay flat (2 m) | Micro jig under a float |
| Sommar | 1 to 5.5 m | dawn & dusk | Shallow bay flat (2 m) | Tiny spoon, Micro jig |
| Höst | 2.5 to 8.5 m | midday | Main-lake point (10 m) | Tiny jig, Small silver spoon |
| Vinter | 3.5 to 11 m | midday | open water | Tungsten mormyshka |
Spring puts ruffe in skinny water — 1 to 4.5 m is the zone. As the season builds they drop to 3 to 9 m, wintering in 4.5 to 12 m. Spring ruffe concentrate at Örekilsälven inflow, a good-rated inflow / creek mouth around 2.5 m. Warm-month bites cluster around early morning and the evening. A micro jig covers the summer program.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk | Örekilsälven inflow (2.5 m) | Tiny bottom jig |
| Sommar | 3 to 9 m | dawn & dusk | open water | Micro jig |
| Höst | 3.5 to 11 m | dusk | open water | Tiny jigging spoon |
| Vinter | 4.5 to 12 m | dusk | open water | Tungsten mormyshka |
