76-acre lake in Finland. The lake tops out around 25 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 Pääjärvi kattaa 30 hehtaaria, rantaviivaa 2.3 km. Allas on yksinkertainen (rantaindeksi 1.2) — lähes malja, joten syvyyskäyrät merkitsevät enemmän kuin ranta. Noin 33% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 0.6 km, leveimmillään 0.6 km. Vesi sijaitsee alueella Kajaanin seutukunta. Lähin kartoitettu vesi on Jokilampi, 1.6 km koilliseen.

The spring pattern is a shallow one: european perch in 1 to 3.5 m. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) gets it done.
| 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 | Shallow bay flat (1 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 |
Start shallow in spring: northern pike sit in 0.5 to 2.5 m that time of year. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. 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 | 2.5 to 6 m | dawn & dusk | Main-lake point (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Main-lake point (2.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: zander in 1 to 4.5 m. As the season builds they drop to 4.5 to 11 m, wintering in 6 to 12 m. Top water on the chart: Main-lake point, a point in the 2.5 m range, prime in fall. Time it for the evening and early morning. Summer baits: a vertical softbait over humps or a deep crankbait gets it done.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Main-lake point (2.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Main-lake point (2.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | open water | Vertical jig / mormyshka with bait, Slow blade bait |
Early season lake whitefish use the shallows, holding in 4.5 to 14 m. Summer is a 7.5 to 25 m game here, winter a 7.5 to 21 m one. The chart's best answer is Deep basin — deep basin, 25 m, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
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 | 4.5 to 14 m | midday & dawn | Break off the point (16 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 7.5 to 25 m chart-limited; documented 12 to 27 m | dawn | Deep basin (25 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Main-lake point (2.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (16 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 7.5 to 21 m is the zone. Warm water sends them out to 7.5 to 25 m; cold water stacks them in 4.5 to 18 m. Deep basin is the standout, a deep basin at roughly 25 m, rated prime for summer burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.

| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 7.5 to 21 m | night & dusk | Deep basin (25 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 7.5 to 25 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (25 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Deep basin (25 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Break off the point (16 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
6 pieces of structure are mapped here — Deep basin, around 25 m, is the deepest of them.

Pääjärvi is about 82 ft (25 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.
Pääjärvi on syvimmillään noin 25 metriä (82 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Pääjärvi. 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 4 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.
