Rating depth structure for northern pike.
Recent public catches load as you reach this section.
159-acre lake in Finland. The lake tops out around 6 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.
Vesi piirtyy 64 hehtaarin laajuisena, rantaa 4.2 km. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.5). Noin 80% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 1.3 km, leveimmillään 0.8 km. Vesi sijaitsee alueella Kehys-Kainuun seutukunta. Lähin kartoitettu vesi on Matalajärvi, 1.6 km koilliseen.

When the water first warms, european perch slide up into 1 to 3.5 m. By summer they slide out to 2 to 6 m, and by winter most fish are in 2 to 6 m. If you only fish one area, make it Shallow bay flat: a weed flat around 1 m that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
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 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2 to 6 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 2 to 6 m chart-limited; documented 3 to 10 m | midday | Deep basin (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 2 to 6 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (6 m) | Tungsten jig + maggots, Small balance jig |
Spring northern pike on Kovajärvi hold shallow, usually 0.5 to 2.5 m. By summer they slide out to 2.5 to 6 m, and by winter most fish are in 1.5 to 4.5 m. The chart's best answer is Shallow bay flat — weed flat, 1 m, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Break off the 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 |
Spring puts lake whitefish in skinny water — 2 to 6 m is the zone. Summer fish stay in 2 to 6 m, and winter fish hold in 2 to 6 m. Deep basin is the standout, a deep basin at roughly 6 m, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 2 to 6 m chart-limited; documented 4.5 to 14 m | midday & dawn | Break off the point (2.5 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 2 to 6 m chart-limited; documented 12 to 27 m | dawn | Deep basin (6 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 1.5 to 6 m chart-limited; documented 2.5 to 9 m | dusk | Break off the point (2.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 2 to 6 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (6 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 2 to 6 m. Even in summer they hold at 2 to 6 m; winter keeps them in 1.5 to 6 m. The chart's best answer is Deep basin — deep basin, 6 m, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

6 pieces of structure are mapped here — Deep basin, around 6 m, is the deepest of them.

Kovajärvi is about 20 ft (6 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.
Kovajärvi on syvimmillään noin 6 metriä (20 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, lake whitefish, burbot on Kovajärvi. 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. The map above holds the full rated-spot list for every 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.
Fishing on Kovajärvi is regulated by the Kalastusrajoitus.fi (official Finnish restriction service). Check the official Finland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
