674-acre lake in Finland. The lake tops out around 20 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Vesi piirtyy 273 hehtaarin laajuisena, rantaa 15.4 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 24% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 4.7 km, leveimmillään 1.3 km. Vesi sijaitsee alueella Raseborgs ekonomiska region. Lähin kartoitettu vesi on Simijärvi eli Iso-Simi, 3.2 km lounaaseen.

Come spring, look for european perch tight to the bank in 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. If you only fish one area, make it Shallow bay flat: a weed flat around 2 m that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow bay flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 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. The chart's best answer is Shallow bay flat — weed flat, 2 m, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (2 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Shallow bay flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Shallow bay flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (2 m) | Tip-ups, Large jigging spoon |
Come spring, look for zander tight to the bank in 1 to 4.5 m. They move out to 4.5 to 11 m in summer and finish the year down in 6 to 12 m. If you only fish one area, make it Main-lake point: a point around 6.5 m that scores prime in fall. Best bite is the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Secondary point (3 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Main-lake point (6.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Main-lake point (6.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Main-lake point (6.5 m) | Vertical jig / mormyshka with bait, Slow blade bait |
In spring, lake whitefish run shallow here, mostly 4.5 to 14 m. Summer pushes them deeper, 6 to 20 m, and winter fish settle into 6 to 20 m. Deep basin is the standout, a deep basin at roughly 20 m, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon 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.

| Kevät | 4.5 to 14 m | midday & dawn | Shallow feeding flat (2 m) | Small jig + waxworm, Blade bait (small) |

Spring burbot on Seljänalanen hold shallow, usually 6 to 20 m. Depth-wise the year is flat: 6 to 20 m in summer, 4.5 to 18 m once it turns cold. The chart's best answer is Deep basin — deep basin, 20 m, prime for spring. Prime time lands in after dark and midday. The summer box starts with a heavy jig + cut bait.

Seljänalanen is about 66 ft (20 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.
Seljänalanen on syvimmillään noin 20 metriä (66 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Seljänalanen. 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 6 ft of water that rates prime for european perch 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.
