3,244-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. What follows comes from the same scoring engine that paints the spots above.
Kartalla Lahnavesi kattaa 1 324 hehtaaria, rantaviivaa 46.2 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 43% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 10.6 km, leveimmillään 4 km. Vesi sijaitsee alueella Mikkelin seutukunta. Lähin kartoitettu vesi on Pieni Pyhävesi, 4.8 km itään.

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. Shallow bay flat is the standout, a weed flat at roughly 1 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 | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Break off the point (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (3.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Sharp break (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 1 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 (1 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Break off the point (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Break off the point (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Back-bay flat (1.5 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 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 (2 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Sharp break (5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Sharp break (5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Sharp break (5 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 26 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 | Sharp break (5 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Deep basin (26 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Rock reef (2 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Deep basin (26 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 9 to 30 m before dropping to 4.5 to 18 m for winter. The spot to know is Deep basin, a deep basin in about 26 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 | Deep basin (26 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 (26 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Deep basin (26 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Rock reef (2 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Lahnavesi carries 12 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 26 m down.

Lahnavesi 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.
Lahnavesi on syvimmillään noin 30 metriä (98 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Lahnavesi. 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 3 ft of water that rates prime for european perch in spring. Open the map above to see every rated 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.
