665-acre lake in Norway. The lake tops out around 63 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 Gjersjøen 269 hektar innenfor 17.2 km strandlinje. Strandlinjen er sterkt oppfliket (indeks 3) — viker og nes overalt, som mangedobler den fiskbare kanten. Omtrent 8% av flaten er grunnere enn ~5 m — der maten finnes. Fra ende til ende måler vannet omtrent 5.6 km, på det bredeste 1.6 km. Vannet ligger i Oppegård kommune. Nærmeste kartlagte vann er Bråtetjern, 6.4 km mot nordøst.
Gratis interaktivt fiskekart — Gjersjøen, Norge: dybdekoter fra ekte dybdemålinger ned til 63 m (208 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.
Spring brown trout on Gjersjøen hold shallow, usually 1 to 7.5 m. By summer they slide out to 7.5 to 18 m, and by winter most fish are in 1.5 to 11 m. The chart's best answer is Break off the point — drop-off, 6 m, prime for winter. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Main-lake point (6 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommer | 7.5 to 18 m | night & dawn | Break off the point (6 m) | Spoon at the thermocline, Deep stickbait (night) |
| Høst | 1.5 to 9 m | dusk & dawn | Main-lake point (6 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Break off the point (6 m) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 1 to 3.5 m. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. Break off the point is the standout, a drop-off at roughly 6 m, rated prime for summer european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (4 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Break off the point (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Høst | 3 to 10 m | midday | Break off the point (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (6 m) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 0.5 to 2.5 m. Midsummer fish sit out in 2.5 to 6 m before dropping to 1.5 to 4.5 m for winter. Spring northern pike concentrate at Back-bay flat, a prime-rated feeding flat around 0.5 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Back-bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommer | 2.5 to 6 m | dawn & dusk | Break off the point (6 m) | Bucktail, Weedless spoon over cabbage |
| Høst | 2 to 5.5 m | midday & dawn | Shallow bay flat (4 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (4 m) | Tip-ups, Large jigging spoon |
Come spring, look for lake whitefish tight to the bank in 4.5 to 14 m. They move out to 12 to 27 m in summer and finish the year down in 7.5 to 21 m. If you only fish one area, make it Break off the point: a drop-off around 6 m that scores prime in spring. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Break off the point (6 m) | Small jig + waxworm, Blade bait (small) |
| Sommer | 12 to 27 m | dawn | Feeding flat (13 m) | Blade bait vertical, Small jigging spoon |
| Høst | 2.5 to 9 m | dusk | Break off the point (6 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Break off the point (6 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for arctic char tight to the bank in 1 to 4.5 m. They move out to 6 to 18 m in summer and finish the year down in 3 to 12 m. If you only fish one area, make it Break off the point: a drop-off around 6 m that scores prime in summer. Best bite is early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | midday & dawn | Shallow bay flat (4 m) | Small casting spoon (silver/orange), Jerkbait (small) |
| Sommer | 6 to 18 m | dawn | Break off the point (6 m) | Jigging spoon vertical, Tube jig (smelt) |
| Høst | 2.5 to 9 m | midday & dusk | Break off the point (6 m) | Casting spoon (orange/gold), Beadhead streamer |
| Vinter | 3 to 12 m | midday & dawn | Break off the point (6 m) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Come spring, look for roach tight to the bank in 0.5 to 3 m. They move out to 1 to 5.5 m in summer and finish the year down in 3.5 to 11 m. If you only fish one area, make it Break off the point: a drop-off around 6 m that scores prime in fall. Best bite is early morning and the evening. A tiny spoon or a micro jig is the honest summer answer here.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Back-bay flat (0.5 m) | Micro jig under a float |
| Sommer | 1 to 5.5 m | dawn & dusk | Shallow bay flat (4 m) | Tiny spoon, Micro jig |
| Høst | 2.5 to 8.5 m | midday | Break off the point (6 m) | Tiny jig, Small silver spoon |
| Vinter | 3.5 to 11 m | midday | Break off the point (6 m) | Tungsten mormyshka |

Gjersjøen is about 208 ft (63 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.

Anglers target brown trout, european perch, northern pike, lake whitefish, arctic char, roach, rudd on Gjersjøen. 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.
Break off the point is the top-rated area: a drop-off in about 20 ft of water that rates prime for roach in fall. Open the map above to see every rated spot for each species and season.
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.
