335-acre lake in Sweden. The lake tops out around 26 m. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What follows comes from the same scoring engine that paints the spots above.
Övre Bolsjön mäter 135 hektar bakom 11.1 km strandlinje. Ett strandindex på 2.7 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 56% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 3.4 km vatten från ena änden till den andra och 1.4 km på bredden. Sjön ligger i Tanum kommun. Siktjärn ligger 1.6 km åt nordost — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Övre Bolsjön, Sverige: ungefärliga djupkurvor ner till 26 m (85 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.
Start shallow in spring: northern pike sit in 0.5 to 2.5 m that time of year. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Top water on the chart: Shallow bay flat, a weed flat in the 2 m range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. 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 | 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 |
The spring pattern is a shallow one: european perch in 1 to 3.5 m. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Top water on the chart: Shallow bay flat, a weed flat in the 2 m range, prime in spring. Time it for early morning. 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 | Shallow bay flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Break off the point (12 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (12 m) | Tungsten jig + maggots, Small balance jig |
Come spring, look for brown trout tight to the bank in 1 to 7.5 m. Expect a summer slide to 7.5 to 18 m, then a winter hold in 1.5 to 11 m. Start at Break off the point. It's a drop-off holding about 12 m of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Main-lake point (6.5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Break off the point (12 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Main-lake point (6.5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Break off the point (12 m) | Jigging spoon, Small stickbait (slow) |
Early season lake whitefish use the shallows, holding in 4.5 to 14 m. Summer is an 8 to 26 m game here, winter a 7.5 to 21 m one. The chart's best answer is Deep basin — deep basin, 22 m, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
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 | 4.5 to 14 m | midday & dawn | Break off the point (12 m) | Small jig + waxworm, Blade bait (small) |
| Sommar | 8 to 26 m chart-limited; documented 12 to 27 m | dawn | Deep basin (22 m) | Blade bait vertical, Small jigging spoon |
| Höst | 2.5 to 9 m | dusk | Main-lake point (6.5 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Deep basin (22 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 7.5 to 21 m is the zone. Warm water sends them out to 8 to 26 m; cold water stacks them in 4.5 to 18 m. Deep basin is the standout, a deep basin at roughly 22 m, rated prime for summer burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.

| Vinter | 4.5 to 18 m | night & dusk | Break off the point (12 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, european smelt slide up into 1 to 7.5 m. Summer is a 7.5 to 21 m game here, winter a 6 to 20 m one. Start at Deep basin. It's a deep basin holding about 22 m of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a tiny vertical spoon or a micro jig rigged through the warm months.

| Vår | 1 to 7.5 m | night & dusk | open water | Micro silver jig, Tiny feather rig |

| Höst | 4.5 to 17 m | dusk | Break off the point (12 m) | Micro jig, Tiny silver spoon |
