424-acre lake in Finland. The lake tops out around 30 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 176 hehtaarin laajuisena, rantaa 10.9 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.3) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 35% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 2.4 km, leveimmillään 1.8 km. Vesi sijaitsee alueella Tampereen seutukunta. Lähin kartoitettu vesi on Äväntäjärvi, 4.8 km pohjoiseen.

When the water first warms, european perch slide up into 1 to 3.5 m. Summer is a 2.5 to 8.5 m game here, winter a 3.5 to 10 m one. Start at Shallow bay flat. It's a weed flat holding about 1 m of water and rates prime come spring. The feeding windows run 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 | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow bay flat (1 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Spring northern pike on Lopenselkä hold shallow, usually 0.5 to 2.5 m. They move out to 2.5 to 6 m in summer and finish the year down in 1.5 to 4.5 m. Put Shallow bay flat first on the milk run — a weed flat near 1 m 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.
| 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 | Main-lake point (3 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Main-lake point (3 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 |
When the water first warms, zander slide up into 1 to 4.5 m. Summer is a 4.5 to 11 m game here, winter a 6 to 12 m one. Start at Main-lake point. It's a point holding about 3 m 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (3 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Main-lake point (3 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Main-lake point (3 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | open water | Vertical jig / mormyshka with bait, Slow blade bait |
Spring puts lake whitefish in skinny water — 4.5 to 14 m is the zone. As the season builds they drop to 12 to 27 m, wintering in 7.5 to 21 m. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 30 m. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Break off the point (17 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Deep basin (30 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Main-lake point (3 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (17 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 7.5 to 21 m. Expect a summer slide to 9 to 30 m, then a winter hold in 4.5 to 18 m. Put Deep basin first on the milk run — a deep basin near 30 m 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.
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 | 7.5 to 21 m | night & dusk | Break off the point (17 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 9 to 30 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (30 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Break off the point (17 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Break off the point (17 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |

Lopenselkä is about 98 ft (30 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.
Lopenselkä on syvimmillään noin 30 metriä (98 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Lopenselkä. 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 4 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.
Fishing on Lopenselkä 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.
