620-acre lake near Börtnan. The lake tops out around 10 m. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
På kartan täcker Börtnen 264 hektar innanför 15.9 km strandlinje, uppbruten av 2 öar. Ett strandindex på 2.8 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 80% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 5 km vatten från ena änden till den andra och 1.1 km på bredden. Sjön ligger i Berg kommun. Lill-Börtnen ligger 4.8 km åt sydost — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Börtnen, Sverige: ungefärliga djupkurvor ner till 10 m (33 fot), och de bästa fiskeplatserna för abborre, öring, sik med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Fish it in early morning and you'll meet the bite. 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 (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 2.5 to 8.5 m | dawn | Deep basin (8.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Deep basin (8.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Deep basin (8.5 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, brown trout slide up into 1 to 7.5 m. Summer is a 3 to 10 m game here, winter a 1.5 to 10 m one. Start at Break off the point. It's a drop-off holding about 4.5 m of water and rates prime come summer. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
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 | 1 to 7.5 m | dawn & dusk | Main-lake point (2.5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 3 to 10 m chart-limited; documented 7.5 to 18 m | night & dawn | Break off the point (4.5 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Main-lake point (2.5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 10 m chart-limited; documented 1.5 to 11 m | dawn | Break off the point (4.5 m) | Jigging spoon, Small stickbait (slow) |
Spring lake whitefish on Börtnen hold shallow, usually 3 to 10 m. Depth-wise the year is flat: 3 to 10 m in summer, 3 to 10 m once it turns cold. The chart's best answer is Deep basin — deep basin, 8.5 m, prime for summer. Prime time lands in early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

| Vinter | 3 to 10 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (8.5 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Time it for early morning and the evening. 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 (1 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Break off the point (4.5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Break off the point (4.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
Spring european grayling on Börtnen hold shallow, usually 0.5 to 3 m. By summer they slide out to 1 to 4.5 m, and by winter most fish are in 2.5 to 7.5 m. The chart's best answer is Break off the point — drop-off, 4.5 m, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a dry fly (caddis, terrestrial) or a nymph under an indicator.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Shallow bay flat (1 m) | Small dry fly (midge, olive), Inline spinner #0-1 |
| Sommar | 1 to 4.5 m | dusk & dawn | Break off the point (4.5 m) | Dry fly (caddis, terrestrial), Nymph under an indicator |
| Höst | 2 to 6 m | midday | Break off the point (4.5 m) | Weighted nymph, Small spoon (copper) |
| Vinter | 2.5 to 7.5 m | midday & dawn | Deep basin (8.5 m) | Tiny jig + maggot, Small mormyshka |
In spring, burbot run shallow here, mostly 3 to 10 m. Summer keeps them at 3 to 10 m, and they winter in 2.5 to 10 m. Deep basin is the standout, a deep basin at roughly 8.5 m, rated prime for spring burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.
