2,184-acre lake near Brattfors. The lake tops out around 64 m. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
På kartan täcker Alstern 902 hektar innanför 52.6 km strandlinje, uppbruten av 7 öar. Strandlinjen är kraftigt flikig (index 4.9) — vikar och uddar överallt, vilket mångdubblar den fiskbara kanten. Cirka 38% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 12.4 km, som bredast 2.1 km. Vattnet hör till Karlstad kommun. Närmaste kartlagda vatten är Lungen, 4.8 km åt nordost.

Early season european perch use the shallows, holding in 1 to 3.5 m. Summer is a 2.5 to 8.5 m game here, winter a 3.5 to 10 m one. The chart's best answer is Shallow bay flat — weed flat, 2 m, prime for spring. Best bite is 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. They move out to 2.5 to 6 m in summer and finish the year down in 1.5 to 4.5 m. If you only fish one area, make it Shallow bay flat: a weed flat around 2 m that scores prime in spring. Best bite is 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. Expect a summer slide to 15 to 37 m, then a winter hold in 4.5 to 18 m. Start at Break off the point. It's a drop-off holding about 29 m of water and rates good come summer. Prime time lands in 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 | open water | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Break off the point (29 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Break off the point (29 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | open water | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts brown trout in skinny water — 1 to 7.5 m is the zone. Warm water sends them out to 7.5 to 18 m; cold water stacks them in 1.5 to 11 m. Main-lake point is the standout, a point at roughly 16 m, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | open water | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Main-lake point (16 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | open water | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | open water | Jigging spoon, Small stickbait (slow) |
