477-acre lake in Norway. The lake tops out around 56 m. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
På kartet dekker Hakkloa 193 hektar innenfor 12.6 km strandlinje. Strandlinjen er sterkt oppfliket (indeks 2.6) — viker og nes overalt, som mangedobler den fiskbare kanten. Omtrent 21% av flaten er grunnere enn ~5 m — der maten finnes. Fra ende til ende måler vannet omtrent 4.2 km, på det bredeste 1.1 km. Vannet ligger i Oslo kommune. Nærmeste kartlagte vann er Hakklokroktjern, 1.6 km mot sørvest.
Gratis interaktivt fiskekart — Hakkloa, Norge: dybdekoter fra ekte dybdemålinger ned til 56 m (184 fot), og de beste fiskeplassene for ørret, abbor, gjedde med flere. Dybdekartet er modellberegnet fra innsjøens virkelige strandlinje og største dybde — bruk det som en veiledning, aldri til navigasjon.
Early season brown trout use the shallows, holding in 1 to 7.5 m. Expect a summer slide to 7.5 to 18 m, then a winter hold in 1.5 to 11 m. Put Break off the point first on the milk run — a drop-off near 14 m that grades prime for summer. In summer the feeding windows fall in after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Main-lake point (5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommer | 7.5 to 18 m | night & dawn | Break off the point (14 m) | Spoon at the thermocline, Deep stickbait (night) |
| Høst | 1.5 to 9 m | dusk & dawn | Main-lake point (5 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Break off the point (14 m) | Jigging spoon, Small stickbait (slow) |
Spring puts european perch in skinny water — 1 to 3.5 m is the zone. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 1 m. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Back-bay flat (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Høst | 3 to 10 m | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Back-bay flat (3.5 m) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Shallow bay flat is the standout, a weed flat at roughly 1 m, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Sommer | 2.5 to 6 m | dawn & dusk | Back-bay flat (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Høst | 2 to 5.5 m | midday & dawn | Back-bay flat (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Back-bay flat (3.5 m) | Tip-ups, Large jigging spoon |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. Summer is a 12 to 27 m game here, winter a 7.5 to 21 m one. Start at Break off the point. It's a drop-off holding about 14 m of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Break off the point (14 m) | Small jig + waxworm, Blade bait (small) |
| Sommer | 12 to 27 m | dawn | Break off the point (14 m) | Blade bait vertical, Small jigging spoon |
| Høst | 2.5 to 9 m | dusk | Main-lake point (5 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Break off the point (14 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, arctic char slide up into 1 to 4.5 m. Summer is a 6 to 18 m game here, winter a 3 to 12 m one. Start at Break off the point. It's a drop-off holding about 14 m of water and rates prime come summer. The feeding windows run early morning. Keep a jigging spoon vertical or a tube jig (smelt) rigged through the warm months.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Sommer | 6 to 18 m | dawn | Break off the point (14 m) | Jigging spoon vertical, Tube jig (smelt) |
| Høst | 2.5 to 9 m | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Vinter | 3 to 12 m | midday & dawn | Break off the point (14 m) | Jigging spoon (glow/silver), Tungsten jig + plastic |

Hakkloa is about 184 ft (56 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Hakkloa er på det dypeste omtrent 56 meter (184 fot). Dybdene kommer fra virkelige målinger.
Anglers target brown trout, european perch, northern pike, lake whitefish, arctic char on Hakkloa. 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 4 ft of water that rates prime for european perch in spring. Every other rated spot, per species and season, is on the map above.
For brown trout, the summer bite is best in after dark and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Hakkloa is regulated by the Norwegian Environment Agency (fishing rules). Check the official Norway regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
