212-acre lake in Norway. The lake tops out around 17 m. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Vannet tegner ut 86 hektar med 8 km strand. Strandlinjen er sterkt oppfliket (indeks 2.5) — viker og nes overalt, som mangedobler den fiskbare kanten. Omtrent 53% av flaten er grunnere enn ~5 m — der maten finnes. Fra ende til ende måler vannet omtrent 3.4 km, på det bredeste 0.6 km. Vannet ligger i Aurskog-Høland kommune. Nærmeste kartlagte vann er Langfossjøen, 3.2 km mot øst.

Dybdekartet er modellberegnet fra innsjøens virkelige strandlinje og største dybde — bruk det som en veiledning, aldri til navigasjon.
In spring, brown trout run shallow here, mostly 1 to 7.5 m. Midsummer fish sit out in 5 to 17 m before dropping to 1.5 to 11 m for winter. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 6.5 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.

| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Main-lake point (2.5 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommer | 5 to 17 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) |
| Høst | 1.5 to 9 m | dusk & dawn | Main-lake point (2.5 m) | Jerkbait over gravel, Casting spoon |

Spring european perch on Tunnsjøen hold shallow, usually 1 to 3.5 m. They move out to 2.5 to 8.5 m in summer and finish the year down in 3.5 to 10 m. Put Shallow bay flat first on the milk run — a weed flat near 1.5 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).
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (1.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Break off the point (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Høst | 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 | Break off the point (6.5 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 0.5 to 2.5 m. Summer is a 2.5 to 6 m game here, winter a 1.5 to 4.5 m one. Start at Shallow bay flat. It's a weed flat holding about 1.5 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.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommer | 2.5 to 6 m | dawn & dusk | Main-lake point (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Høst | 2 to 5.5 m | midday & dawn | Shallow bay flat (1.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (1.5 m) | Tip-ups, Large jigging spoon |
Start shallow in spring: lake whitefish sit in 4.5 to 14 m that time of year. Summer pushes them deeper, 5 to 17 m, and winter fish settle into 5 to 17 m. The spot to know is Deep basin, a deep basin in about 16 m of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Break off the point (6.5 m) | Small jig + waxworm, Blade bait (small) |
| Sommer | 5 to 17 m chart-limited; documented 12 to 27 m | dawn | Deep basin (16 m) | Blade bait vertical, Small jigging spoon |
| Høst | 2.5 to 9 m | dusk | Break off the point (6.5 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 5 to 17 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (16 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: arctic char sit in 1 to 4.5 m that time of year. Summer pushes them deeper, 5 to 17 m, and winter fish settle into 3 to 12 m. The spot to know is Deep basin, a deep basin in about 16 m of water that rates prime for arctic char in summer. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

Start shallow in spring: roach sit in 0.5 to 3 m that time of year. Summer pushes them deeper, 1 to 5.5 m, and winter fish settle into 3.5 to 11 m. The spot to know is Shallow bay flat, a weed flat in about 1.5 m of water that rates prime for roach in spring. Warm-month bites cluster around early morning and the evening. Throw a tiny spoon or a micro jig until the fish tell you otherwise.

Anglers target brown trout, european perch, northern pike, lake whitefish, arctic char, roach on Tunnsjøen. 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 5 ft of water that rates prime for european perch in spring. Scroll up to the map for the complete spot list by 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.
