5,192-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. Every species below gets its seasonal read from the same numbers driving the chart.
Vesi piirtyy 2 091 hehtaarin laajuisena, rantaa 41.5 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 27% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 15.3 km, leveimmillään 2.7 km. Vesi sijaitsee alueella Savonlinnan seutukunta. Lähin kartoitettu vesi on Alaset, 4.8 km itään.

When the water first warms, european perch slide up into 1 to 3.5 m. By summer they slide out to 2.5 to 8.5 m, and by winter most fish are in 3.5 to 10 m. If you only fish one area, make it Weed 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (10 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (10 m) | Tungsten jig + maggots, Small balance jig |
Spring northern pike on Kolkonjärvi 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, 0.5 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 (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Sharp break (5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Sharp break (5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2 m) | Tip-ups, Large jigging spoon |
When the water first warms, zander slide up into 1 to 4.5 m. By summer they slide out to 4.5 to 11 m, and by winter most fish are in 6 to 12 m. If you only fish one area, make it Break off the point: a drop-off around 10 m that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a vertical softbait over humps or a deep crankbait rigged through the warm months.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (1 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (10 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (10 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (10 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Spring puts lake whitefish in skinny water — 4.5 to 14 m is the zone. Warm water sends them out to 6 to 20 m; cold water stacks them in 6 to 20 m. Deep basin is the standout, a deep basin at roughly 20 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.
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 (10 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 6 to 20 m chart-limited; documented 12 to 27 m | dawn | Deep basin (20 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Rock reef (1 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 6 to 20 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (20 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 6 to 20 m. Even in summer they hold at 6 to 20 m; winter keeps them in 4.5 to 18 m. The chart's best answer is Deep basin — deep basin, 20 m, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

Kolkonjärvi 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.
Kolkonjärvi on syvimmillään noin 20 metriä (66 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Kolkonjärvi. 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.
Weed 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.
