Rating depth structure for zander.
Recent public catches load as you reach this section.
1,431-acre lake in Sweden. The lake tops out around 14 m. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
Vattnet ritar ut 578 hektar med 12.6 km strand. Strandlinjen är måttligt strukturerad (index 1.5) — tillräckligt med uddar och vikar att fiska av. Cirka 21% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 4 km, som bredast 2.1 km. Vattnet hör till Karlstad kommun. Närmaste kartlagda vatten är Samstorptjärnet, 8 km åt norr.
Gratis interaktiv fiskekarta — Alstern, Sverige: ungefärliga djupkurvor ner till 14 m (47 fot), och de bästa fiskeplatserna för gädda, abborre, öring med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
Spring northern pike on Alstern hold shallow, usually 0.5 to 2.5 m. By summer they slide out to 2.5 to 6 m, and by winter most fish are in 1.5 to 4.5 m. The chart's best answer is Shallow bay flat — weed flat, 2 m, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 |
When the water first warms, european perch slide up into 1 to 3.5 m. By summer they slide out to 2.5 to 8.5 m, and by winter most fish are in 3.5 to 10 m. If you only fish one area, make it Shallow bay flat: a weed flat around 2 m that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| 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 | Break off the point (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Break off the point (6.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Deep basin (12 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: brown trout sit in 1 to 7.5 m that time of year. Summer pushes them deeper, 4.5 to 14 m, and winter fish settle into 1.5 to 11 m. The spot to know is Break off the point, a drop-off in about 6.5 m of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Main-lake point (3.5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 4.5 to 14 m chart-limited; documented 7.5 to 18 m | night & dawn | Break off the point (6.5 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Main-lake point (3.5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Break off the point (6.5 m) | Jigging spoon, Small stickbait (slow) |
Spring puts lake whitefish in skinny water — 4.5 to 14 m is the zone. Warm water sends them out to 4.5 to 14 m; cold water stacks them in 4.5 to 14 m. Deep basin is the standout, a deep basin at roughly 12 m, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

| Vinter | 4.5 to 14 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (12 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 4.5 to 14 m. Even in summer they hold at 4.5 to 14 m; winter keeps them in 3.5 to 14 m. The chart's best answer is Deep basin — deep basin, 12 m, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

Start shallow in spring: common bream sit in 1 to 4.5 m that time of year. Warm water sends them out to 2.5 to 7.5 m; cold water stacks them in 5.5 to 14 m. Top water on the chart: Deep basin, a deep basin in the 12 m range, prime in winter. Fish it in early morning and the evening and you'll meet the bite.

Alstern is about 47 ft (14 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.

This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 6 ft of water that rates prime for northern pike in spring. The map above holds the full rated-spot list for every species and season.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
