5,461-acre lake near Nälden. The lake tops out around 33 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. Here is how the season plays out for each species, straight from the data behind the map.
Alsensjön mäter 2 215 hektar bakom 49.4 km strandlinje, uppbruten av 8 öar. Strandlinjen är kraftigt flikig (index 3) — vikar och uddar överallt, vilket mångdubblar den fiskbara kanten. Cirka 44% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 17.2 km, som bredast 3.4 km. Vattnet hör till Krokom kommun. Närmaste kartlagda vatten är Näldsjön, 9.7 km åt nordost.
Gratis interaktiv fiskekarta — Alsensjön, Sverige: ungefärliga djupkurvor ner till 33 m (108 fot), och de bästa fiskeplatserna för abborre, gädda, sik med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Come spring, look for european perch tight to the bank 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. 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. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| 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 | Sharp break (7.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Sharp break (7.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Sharp break (7.5 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding 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. 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 and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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, lake whitefish run shallow here, mostly 4.5 to 14 m. Midsummer fish sit out in 12 to 27 m before dropping to 7.5 to 21 m for winter. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 3.5 m. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Sharp break (7.5 m) | Small jig + waxworm, Blade bait (small) |
| Sommar | 12 to 27 m | dawn | Deep basin (28 m) | Blade bait vertical, Small jigging spoon |
| Höst | 2.5 to 9 m | dusk | Rock reef (3.5 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Sharp break (7.5 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: brown trout in 1 to 7.5 m. As the season builds they drop to 7.5 to 18 m, wintering in 1.5 to 11 m. Top water on the chart: Sharp break, a drop-off in the 7.5 m range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Shoreline point (3 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Sharp break (7.5 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Rock reef (3.5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Sharp break (7.5 m) | Jigging spoon, Small stickbait (slow) |
In spring, european grayling run shallow here, mostly 0.5 to 3 m. Midsummer fish sit out in 1 to 4.5 m before dropping to 2.5 to 7.5 m for winter. Winter european grayling concentrate at Sharp break, a prime-rated drop-off around 7.5 m. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a dry fly (caddis, terrestrial) or a nymph under an indicator most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Shallow bay flat (2 m) | Small dry fly (midge, olive), Inline spinner #0-1 |
| Sommar | 1 to 4.5 m | dusk & dawn | Shallow bay flat (2 m) | Dry fly (caddis, terrestrial), Nymph under an indicator |
| Höst | 2 to 6 m | midday | Sharp break (7.5 m) | Weighted nymph, Small spoon (copper) |
| Vinter | 2.5 to 7.5 m | midday & dawn | Sharp break (7.5 m) | Tiny jig + maggot, Small mormyshka |
Spring burbot on Alsensjön hold shallow, usually 7.5 to 21 m. They move out to 10 to 33 m in summer and finish the year down in 4.5 to 18 m. Put Deep basin first on the milk run — a deep basin near 28 m that grades prime for summer. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Sharp break (7.5 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 10 to 33 m | night & midday | Deep basin (28 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Sharp break (11 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Rock reef (3.5 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
