13-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. What the data behind the map says about each species, season by season:
Kartalla Alimmainen Käärmejärvi kattaa 5 hehtaaria, rantaviivaa 1.3 km. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.6). Noin 89% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 0.5 km, leveimmillään 0.3 km. Vesi sijaitsee alueella Kehys-Kainuun seutukunta. Lähin kartoitettu vesi on Keskimmäinen Käärmejärvi, 0 km pohjoiseen.

The spring pattern is a shallow one: european perch in 1 to 3.5 m. As the season builds they drop to 2 to 6 m, wintering in 2 to 6 m. Top water on the chart: Deep basin, a deep basin in the 6 m range, prime in fall. Time it for early morning. 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 3.5 m | midday & dawn | Break off the point (4 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 |
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: Break off the point, a drop-off in the 4 m range, prime in fall. 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.

|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Break off the point (4 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Break off the point (4 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Break off the point (4 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 2 to 6 m, wintering in 2 to 6 m. Top water on the chart: Break off the point, a drop-off in the 4 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 (1 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 2 to 6 m chart-limited; documented 4.5 to 11 m | dusk & dawn | Break off the point (4 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 2 to 6 m chart-limited; documented 3.5 to 12 m | dusk & night | Break off the point (4 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 2 to 6 m chart-limited; documented 6 to 12 m | dusk & dawn | Deep basin (6 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Early season lake whitefish use the shallows, holding in 2 to 6 m. Even in summer they hold at 2 to 6 m; winter keeps them in 2 to 6 m. The chart's best answer is Deep basin — deep basin, 6 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.

| 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 (4 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 (4 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 |
Spring puts burbot in skinny water — 2 to 6 m is the zone. Summer fish stay in 2 to 6 m, and winter fish hold in 1.5 to 6 m. Deep basin is the standout, a deep basin at roughly 6 m, rated prime for spring burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.

Anglers target european perch, northern pike, zander, lake whitefish, burbot on Alimmainen Käärmejärvi. 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.
Deep basin is the top-rated area: a deep basin in about 19 ft of water that rates prime for european perch in fall. 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.
