710-acre lake in Finland. The lake tops out around 15 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Kartalla Ahjärvi kattaa 289 hehtaaria, rantaviivaa 18.5 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.1) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 63% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 3.7 km, leveimmillään 2.4 km. Vesi sijaitsee alueella Imatran seutukunta. Lähin kartoitettu vesi on Kivenkänä, 4.8 km länteen.

Spring puts european perch in skinny water — 1 to 3.5 m is the zone. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 1 m. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| 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 | Break off the point (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (3.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (3.5 m) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Shallow bay flat is the standout, a weed flat at roughly 1 m, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| 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 (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Break off the point (3.5 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 zander in skinny water — 1 to 4.5 m is the zone. As the season builds they drop to 4.5 to 11 m, wintering in 6 to 12 m. Fall zander concentrate at Break off the point, a prime-rated drop-off around 3.5 m. Warm-month bites cluster around the evening and early morning. A vertical softbait over humps or a deep crankbait covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (2 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (3.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (3.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Deep basin (15 m) | Vertical jig / mormyshka with bait, Slow blade bait |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. Summer is a 4.5 to 15 m game here, winter a 4.5 to 15 m one. Start at Deep basin. It's a deep basin holding about 15 m of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon 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.

| Kevät | 4.5 to 14 m | midday & dawn | Shallow feeding flat (6 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 4.5 to 15 m chart-limited; documented 12 to 27 m | dawn | Deep basin (15 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Break off the point (3.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 4.5 to 15 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (15 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 4.5 to 15 m that time of year. They don't go far with the seasons — 4.5 to 15 m covers summer, 3.5 to 15 m covers winter. Top water on the chart: Deep basin, a deep basin in the 15 m range, prime in spring. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.

Anglers target european perch, northern pike, zander, lake whitefish, burbot on Ahjärvi. 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. Scroll up to the map for the complete spot list by 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.
