3,687-acre lake in Finland. The lake tops out around 35 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Kartalla Syvänsi kattaa 1 597 hehtaaria, rantaviivaa 57.9 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 4.1) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 55% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 12.2 km, leveimmillään 3.4 km. Vesi sijaitsee alueella Pieksämäen seutukunta. Lähin kartoitettu vesi on Vihtajärvi, 3.2 km koilliseen.

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. Weed flat is the standout, a weed flat at roughly 2 m, rated prime for spring 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (3.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Sharp break (3.5 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 Shallow bay flat, a prime-rated weed 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Weed flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Sharp break (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2 m) | Tip-ups, Large jigging spoon |
In spring, zander run shallow here, mostly 1 to 4.5 m. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. Sharp break is the standout, a drop-off at roughly 3.5 m, rated prime for fall zander. Time it for the evening and early morning. You won't need more than a vertical softbait over humps or a deep crankbait most summer days.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (1 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Secondary point (4 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Sharp break (3.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Sharp break (15 m) | Vertical jig / mormyshka with bait, Slow blade bait |
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 Deep basin: a deep basin around 28 m that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Shallow feeding flat (7 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Deep basin (28 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Rock reef (1 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Sharp break (15 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: burbot in 7.5 to 21 m. Midsummer fish sit out in 11 to 35 m before dropping to 4.5 to 18 m for winter. The spot to know is Deep basin, a deep basin in about 28 m of water that rates prime for burbot in summer. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 7.5 to 21 m | night & dusk | Sharp break (15 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 11 to 35 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (28 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Sharp break (15 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Rock reef (1 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 14 features, led in depth by Deep basin at roughly 28 m.

Syvänsi is about 115 ft (35 m) deep at its deepest point. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Syvänsi on syvimmillään noin 35 metriä (115 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Syvänsi. 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.
Weed flat is the top-rated area: a weed flat in about 7 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 european perch, the summer bite is best in 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 Syvänsi is regulated by the Kalastusrajoitus.fi (official Finnish restriction service). Check the official Finland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
