991-acre lake in Finland. The lake tops out around 35 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Vesi piirtyy 407 hehtaarin laajuisena, rantaa 19.3 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.7) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 33% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 7.1 km, leveimmillään 1.1 km. Vesi sijaitsee alueella Kehys-Kainuun seutukunta. Lähin kartoitettu vesi on Pieni-Peranka, 3.2 km lounaaseen.

Come spring, look for european perch tight to the bank in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Start at Shallow bay flat. It's a weed flat holding about 2 m of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow bay flat (2 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 | Shallow feeding flat (9 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Put Shallow bay flat first on the milk run — a weed flat near 2 m that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (2 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Shallow bay flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Shallow bay flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (2 m) | Tip-ups, Large jigging spoon |
In spring, lake whitefish run shallow here, mostly 4.5 to 14 m. Midsummer fish sit out in 12 to 27 m before dropping to 7.5 to 21 m for winter. Summer lake whitefish concentrate at Break off the point, a prime-rated drop-off around 16 m. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Shallow feeding flat (9 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Break off the point (16 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Secondary point (3 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (16 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring burbot on Iso-Peranka hold shallow, usually 7.5 to 21 m. They move out to 11 to 35 m in summer and finish the year down in 4.5 to 18 m. Put Deep basin first on the milk run — a deep basin near 34 m that grades prime for summer. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
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 (16 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 11 to 35 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (34 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Break off the point (16 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Break off the point (16 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 8 features, led in depth by Deep basin at roughly 34 m.

Iso-Peranka is about 115 ft (35 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.
Iso-Peranka on syvimmillään noin 35 metriä (115 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, lake whitefish, burbot on Iso-Peranka. 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 7 ft of water that rates prime for european perch in spring. 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.
Fishing on Iso-Peranka 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.
