11-acre lake in Sweden. The lake tops out around 4.5 m. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
På kartan täcker Kroktjärn 4 hektar innanför 1 km strandlinje. Bassängen är enkel (strandindex 1.2) — nästan en skål, så djupkurvorna betyder mer än stranden. Inget här går djupare än ~5 m: en enda stor grundzon med föda och skydd. Vattnet hör till Ale kommun. Närmaste kartlagda vatten är Mollsjön, 1.6 km åt söder.
Gratis interaktiv fiskekarta — Kroktjärn, Sverige: ungefärliga djupkurvor ner till 4 m (14 fot), och de bästa fiskeplatserna för gädda, abborre och öring. 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 2.5 m. Summer is a 1 to 4.5 m game here, winter a 1 to 4.5 m one. Start at Shallow bay flat. It's a weed flat holding about 1 m of water and rates prime come spring. The feeding windows run 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 2.5 m | midday & dawn | Shallow bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 1 to 4.5 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Shallow bay flat (1 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 1 to 4.5 m chart-limited; documented 2 to 5.5 m | midday & dawn | Shoreline break (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1 to 4.5 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 Kroktjärn hold shallow, usually 1 to 3.5 m. They move out to 1 to 4.5 m in summer and finish the year down in 1 to 4.5 m. Put Shallow bay flat first on the milk run — a weed flat near 1 m that grades prime for spring. The feeding windows run 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 | 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 1 to 4.5 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 1 to 4.5 m chart-limited; documented 3 to 10 m | midday | Deep basin (3.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 1 to 4.5 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (3.5 m) | Tungsten jig + maggots, Small balance jig |
In spring, brown trout run shallow here, mostly 0.5 to 4.5 m. Summer keeps them at 1 to 4.5 m, and they winter in 0.5 to 4.5 m. Summer brown trout concentrate at Shoreline break, a prime-rated drop-off around 2 m. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

Anglers target northern pike, european perch, brown trout on Kroktjärn. 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. Every other rated spot, per species and season, is on the map above.
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.
