638-acre lake in Finland. The lake tops out around 82 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Species by species, here's what the data says the year looks like.
The drawn water covers 638 acres wrapped in 6.6 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. About 49% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.

When the water first warms, european perch slide up into 3 to 12 ft. Summer is a 8 to 28 ft game here, winter a 12 to 33 ft one. Start at Break off the point. It's a drop-off holding about 15 ft of water and rates prime come summer. The feeding windows run early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (15 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |

Spring northern pike on Oriselkä hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

When the water first warms, zander slide up into 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. Start at Break off the point. It's a drop-off holding about 15 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a vertical softbait over humps or a deep crankbait rigged through the warm months.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 25 to 82 ft, wintering in 25 to 70 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 82 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 25 to 82 ft | dawn | Deep basin (82 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (15 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (82 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 25 to 70 ft. Expect a summer slide to 25 to 82 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 82 ft that grades prime for summer. In summer the feeding windows fall in after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (82 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |

Oriselkä is about 82 ft (25 m) deep at its deepest point. The depth chart here comes from real state fisheries GPS surveys, so the contours reflect measured depths.
Anglers target zander, northern pike, european perch, lake whitefish, burbot on Oriselkä. 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 2 ft of water that rates prime for northern pike in spring. Every other rated spot, per species and season, is on the map above.
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 Oriselkä 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.
