266-acre lake in Finland. The lake tops out around 3 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 Aapajärvi kattaa 110 hehtaaria, rantaviivaa 9.5 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Koko vesi on matalampaa kuin ~5 m — kasvillisuutta ja saaliskalaa rannasta rantaan. Päästä päähän vesi mittaa noin 3.2 km, leveimmillään 1.1 km. Vesi sijaitsee alueella Kemi-Tornion seutukunta. Lähin kartoitettu vesi on Skomakarfjärden, 38.6 km etelään.

The spring pattern is a shallow one: european perch in 1 to 3 m. The depth story barely changes: 1 to 3 m through summer, 1 to 3 m in winter. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for european perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) 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 | 1 to 3 m chart-limited; documented 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 1 to 3 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (3 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 1 to 3 m chart-limited; documented 3 to 10 m | midday | Deep basin (3 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 1 to 3 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (3 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 0.5 to 2.5 m that time of year. Summer pushes them deeper, 1 to 3 m, and winter fish settle into 1 to 3 m. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

| 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 | 1 to 3 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Shallow bay flat (1 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 1 to 3 m chart-limited; documented 2 to 5.5 m | midday & dawn | Shallow bay flat (1 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1 to 3 m chart-limited; documented 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
Early season lake whitefish use the shallows, holding in 1 to 3 m. Even in summer they hold at 1 to 3 m; winter keeps them in 1 to 3 m. Put Deep basin first on the milk run — a deep basin near 3 m that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3 m chart-limited; documented 4.5 to 14 m | midday & dawn | Break off the point (1.5 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 1 to 3 m chart-limited; documented 12 to 27 m | dawn | Deep basin (3 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 1 to 3 m chart-limited; documented 2.5 to 9 m | dusk | Break off the point (1.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 1 to 3 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (3 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 1 to 3 m is the zone. Summer fish stay in 1 to 3 m, and winter fish hold in 1 to 3 m. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 3 m. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.

Aapajärvi is about 10 ft (3 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.
Aapajärvi on syvimmillään noin 3 metriä (10 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, lake whitefish, burbot on Aapajärvi. 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.
