Rating depth structure for northern pike.

276-acre lake in Sweden. The lake tops out around 2 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. What the data behind the map says about each species, season by season:
Grundträsket mäter 111 hektar bakom 6.4 km strandlinje. Strandlinjen är måttligt strukturerad (index 1.7) — tillräckligt med uddar och vikar att fiska av. Inget här går djupare än ~5 m: en enda stor grundzon med föda och skydd. Från ände till ände mäter vattnet ungefär 1.8 km, som bredast 1.1 km. Vattnet hör till Älvsbyn kommun. Närmaste kartlagda vatten är Uddträsket, 1.6 km åt sydost.
Gratis interaktiv fiskekarta — Grundträsket, Sverige: ungefärliga djupkurvor ner till 2 m (7 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.
When the water first warms, northern pike slide up into 0.5 to 2 m. There's no big seasonal slide here — summer means 0.5 to 2 m, winter 0.5 to 2 m. If you only fish one area, make it Shallow bay flat: a weed flat around 1 m that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2 m chart-limited; documented 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 0.5 to 2 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Shallow bay flat (1 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 0.5 to 2 m chart-limited; documented 2 to 5.5 m | midday & dawn | Shallow bay flat (1 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 0.5 to 2 m chart-limited; documented 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
Spring european perch on Grundträsket hold shallow, usually 0.5 to 2 m. Depth-wise the year is flat: 0.5 to 2 m in summer, 0.5 to 2 m once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 1 m, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).

| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2 m chart-limited; documented 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 0.5 to 2 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 0.5 to 2 m chart-limited; documented 3 to 10 m | midday | Deep basin (2 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 0.5 to 2 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (2 m) | Tungsten jig + maggots, Small balance jig |
In spring, brown trout run shallow here, mostly 0.5 to 2 m. Summer keeps them at 0.5 to 2 m, and they winter in 0.5 to 2 m. Break off the point is the standout, a drop-off at roughly 1 m, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

|---|---|---|---|---|
| Vår | 0.5 to 2 m chart-limited; documented 1 to 7.5 m | dawn & dusk | Main-lake point (2 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 0.5 to 2 m chart-limited; documented 7.5 to 18 m | night & dawn | Break off the point (1 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 0.5 to 2 m chart-limited; documented 1.5 to 9 m | dusk & dawn | Main-lake point (2 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 0.5 to 2 m chart-limited; documented 1.5 to 11 m | dawn | Break off the point (1 m) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: lake whitefish sit in 0.5 to 2 m that time of year. They don't go far with the seasons — 0.5 to 2 m covers summer, 0.5 to 2 m covers winter. Top water on the chart: Deep basin, a deep basin in the 2 m range, good in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

When the water first warms, burbot slide up into 0.5 to 2 m. There's no big seasonal slide here — summer means 0.5 to 2 m, winter 0.5 to 2 m. Start at Deep basin. It's a deep basin holding about 2 m of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.

Grundträsket is about 7 ft (2 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.

Anglers target northern pike, european perch, brown trout, lake whitefish, burbot on Grundträsket. 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 3 ft of water that rates prime for northern pike in spring. Scroll up to the map for the complete spot list by 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.
