2,728-acre lake in Finland. The lake tops out around 40 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:
Vesi piirtyy 1 236 hehtaarin laajuisena, rantaa 44.7 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 63% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 8.5 km, leveimmillään 3.5 km. Vesi sijaitsee alueella North Eastern Savonia. Lähin kartoitettu vesi on Ala-Nurmes, 14.5 km luoteeseen.

Early season european perch use the shallows, holding in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Put Shallow bay flat first on the milk run — a weed flat near 2.5 m that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (2.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Break off the point (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (9 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Sharp break (9 m) | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Start at Back-bay flat. It's a weed flat holding about 1 m of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Back-bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Shallow bay flat (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Shallow bay flat (2.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (2.5 m) | Tip-ups, Large jigging spoon |
Early season zander use the shallows, holding in 1 to 4.5 m. Expect a summer slide to 4.5 to 11 m, then a winter hold in 6 to 12 m. Put Sharp break first on the milk run — a drop-off near 9 m that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a vertical softbait over humps or a deep crankbait and you're in the game.
| 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 | Sharp break (9 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Sharp break (9 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Sharp break (9 m) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: lake whitefish in 4.5 to 14 m. Midsummer fish sit out in 12 to 27 m before dropping to 7.5 to 21 m for winter. The spot to know is Sharp break, a drop-off in about 9 m of water that rates prime for lake whitefish in spring. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Sharp break (9 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Sharp break (9 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Rock reef (0.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Sharp break (9 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for burbot tight to the bank in 7.5 to 21 m. They move out to 15 to 37 m in summer and finish the year down in 4.5 to 18 m. If you only fish one area, make it Deep basin: a deep basin around 40 m that scores prime in summer. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 7.5 to 21 m | night & dusk | Sharp break (9 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 15 to 37 m | night & midday | Deep basin (40 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Sharp break (9 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Sharp break (9 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 14 features, led in depth by Deep basin at roughly 40 m.

Anglers target european perch, northern pike, zander, lake whitefish, burbot on Ala-Siikajärvi. 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 9 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.
