1,137-acre lake near Sunnemo. The lake tops out around 48 m. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
På kartan täcker Grässjön 466 hektar innanför 13.7 km strandlinje. Strandlinjen är måttligt strukturerad (index 1.8) — tillräckligt med uddar och vikar att fiska av. Cirka 26% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 5.5 km, som bredast 1.4 km. Vattnet hör till Hagfors kommun. Närmaste kartlagda vatten är Lillsjön, 3.2 km åt väster.
Gratis interaktiv fiskekarta — Grässjön, Sverige: ungefärliga djupkurvor ner till 48 m (157 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.
Early season european perch use the shallows, holding in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Put Shallow bay flat first on the milk run — a weed flat near 2 m that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| 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 |
Come spring, look for northern pike tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 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 bucktail or a weedless spoon over cabbage is the honest summer answer here.
| 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 |
Come spring, look for burbot tight to the bank in 7.5 to 21 m. They move out to 15 to 37 m in summer and finish the year down in 4.5 to 18 m. If you only fish one area, make it Deep basin: a deep basin around 41 m that scores prime in summer. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Break off the point (22 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Deep basin (41 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Break off the point (22 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Break off the point (22 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Early season zander use the shallows, holding in 1 to 4.5 m. Expect a summer slide to 4.5 to 11 m, then a winter hold in 6 to 12 m. Put Main-lake point first on the milk run — a point near 12 m that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a vertical softbait over humps or a deep crankbait and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | open water | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Main-lake point (12 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Main-lake point (12 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Main-lake point (12 m) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: roach in 0.5 to 3 m. Midsummer fish sit out in 1 to 5.5 m before dropping to 3.5 to 11 m for winter. The spot to know is Shallow bay flat, a weed flat in about 2 m of water that rates prime for roach in spring. Plan around early morning and the evening in the warm months. Summer baits: a tiny spoon or a micro jig gets it done.
| 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 | open water | Tiny jig, Small silver spoon |
| Vinter | 3.5 to 11 m | midday | open water | Tungsten mormyshka |
When the water first warms, ruffe slide up into 1 to 4.5 m. By summer they slide out to 3 to 9 m, and by winter most fish are in 4.5 to 12 m. In summer the feeding windows fall in early morning and the evening. Keep a micro jig rigged through the warm months.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk | open water | 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 |
