3,465-acre lake in Norway. The lake tops out around 94 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.
Vannet tegner ut 1 399 hektar med 43.3 km strand. Strandlinjen er sterkt oppfliket (indeks 3.3) — viker og nes overalt, som mangedobler den fiskbare kanten. Omtrent 5% av flaten er grunnere enn ~5 m — der maten finnes. Fra ende til ende måler vannet omtrent 9.2 km, på det bredeste 4.3 km. Vannet ligger i Trondheim kommune. Nærmeste kartlagte vann er Selbusjøen, 17.7 km mot sørøst.
Gratis interaktivt fiskekart — Jonsvatnet, Norge: dybdekoter fra ekte dybdemålinger ned til 94 m (310 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.
In spring, brown trout run shallow here, mostly 1 to 7.5 m. Summer pushes them deeper, 7.5 to 18 m, and winter fish settle into 1.5 to 11 m. Sharp break is the standout, a drop-off at roughly 9.5 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.
| 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 | Sharp break (9.5 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 | Sharp break (9.5 m) | Jigging spoon, Small stickbait (slow) |
Spring european perch on Jonsvatnet hold shallow, usually 1 to 3.5 m. By summer they slide out to 2.5 to 8.5 m, and by winter most fish are in 3.5 to 10 m. The chart's best answer is Sharp break — drop-off, 9.5 m, prime for fall. Prime time lands in 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 (5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Sharp break (9.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Høst | 3 to 10 m | midday | Sharp break (9.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Sharp break (9.5 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 0.5 to 2.5 m. By summer they slide out to 2.5 to 6 m, and by winter most fish are in 1.5 to 4.5 m. If you only fish one area, make it Main-lake point: a point around 5 m that scores prime in fall. 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.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Sommer | 2.5 to 6 m | dawn & dusk | Shallow bay flat (5 m) | Bucktail, Weedless spoon over cabbage |
| Høst | 2 to 5.5 m | midday & dawn | Main-lake point (5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (5 m) | Tip-ups, Large jigging spoon |
Start shallow in spring: lake whitefish sit in 4.5 to 14 m that time of year. Warm water sends them out to 12 to 27 m; cold water stacks them in 7.5 to 21 m. Top water on the chart: Sharp break, a drop-off in the 9.5 m range, prime in spring. 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.

|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Sharp break (9.5 m) | Small jig + waxworm, Blade bait (small) |

Start shallow in spring: arctic char sit in 1 to 4.5 m that time of year. Warm water sends them out to 6 to 18 m; cold water stacks them in 3 to 12 m. Top water on the chart: Sharp break, a drop-off in the 9.5 m range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

When the water first warms, burbot slide up into 7.5 to 21 m. Summer is a 15 to 37 m game here, winter a 4.5 to 18 m one. Start at Sharp break. It's a drop-off holding about 9.5 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.

Jonsvatnet is about 310 ft (94 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, burbot, european eel on Jonsvatnet. 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.
Sharp break is the top-rated area: a drop-off in about 31 ft of water that rates prime for brown trout in summer. 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.
