899-acre lake near Järvsö. The lake tops out around 23 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. What follows comes from the same scoring engine that paints the spots above.
Vattnet ritar ut 361 hektar med 13.4 km strand. Strandlinjen är måttligt strukturerad (index 2) — tillräckligt med uddar och vikar att fiska av. Ungefär 44% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 5.1 km vatten från ena änden till den andra och 1.3 km på bredden. Sjön ligger i Ljusdal kommun. Uvåssjön ligger 1.6 km åt väster — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Kalvsjön, Sverige: ungefärliga djupkurvor ner till 23 m (75 fot), och de bästa fiskeplatserna för abborre, gädda och gös. 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. 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 Shallow bay flat, a weed flat in about 2 m of water that rates prime for european perch in spring. 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 | Shallow bay flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Break off the point (10 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (10 m) | Tungsten jig + maggots, Small balance jig |
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 weed 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 | 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 |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. The spot to know is Break off the point, a drop-off in about 10 m of water that rates prime for zander in fall. Warm-month bites cluster around the evening and early morning. Throw a vertical softbait over humps or a deep crankbait until the fish tell you otherwise.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | Main-lake point (6 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Break off the point (10 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Break off the point (10 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Break off the point (10 m) | Vertical jig / mormyshka with bait, Slow blade bait |
