1,065-acre lake in Finland. The lake tops out around 30 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Kartalla Viheri kattaa 437 hehtaaria, rantaviivaa 20.4 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.8) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 61% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 6 km, leveimmillään 2.3 km. Vesi sijaitsee alueella Joutsa. Lähin kartoitettu vesi on Vähä Säynätjärvi, 4.8 km länteen.

Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. The spot to know is Shallow bay flat, a weed flat in about 0.5 m of water that rates prime for european perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (0.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow feeding flat (7.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (11 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Shallow feeding flat (7.5 m) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 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. The spot to know is Shallow bay flat, a weed flat in about 0.5 m of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| 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 | Main-lake point (3 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Main-lake point (3 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Main-lake point (3 m) | Tip-ups, Large jigging spoon |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. The spot to know is Break off the point, a drop-off in about 11 m of water that rates prime for zander in fall. Warm-month bites cluster around the evening and early morning. Throw a vertical softbait over humps or a deep crankbait until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (3 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (11 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (11 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (11 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Spring lake whitefish on Viheri hold shallow, usually 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. Put Deep basin first on the milk run — a deep basin near 30 m that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Break off the point (11 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Deep basin (30 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Main-lake point (3 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (11 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, burbot run shallow here, mostly 7.5 to 21 m. Midsummer fish sit out in 9 to 30 m before dropping to 4.5 to 18 m for winter. Summer burbot concentrate at Deep basin, a prime-rated deep basin around 30 m. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.
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 | Break off the point (11 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 9 to 30 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (30 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Break off the point (11 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Break off the point (11 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |

Viheri is about 98 ft (30 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.
Viheri on syvimmillään noin 30 metriä (98 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Viheri. 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 2 ft of water that rates prime for northern pike in spring. The interactive chart above rates every spot for each 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.
