121-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.
Vesi piirtyy 49 hehtaarin laajuisena, rantaa 5.3 km. Rantaviiva on kohtalaisen rikkonainen (indeksi 2.1). Noin 56% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 1.4 km, leveimmillään 0.6 km. Vesi sijaitsee alueella Kehys-Kainuun seutukunta. Lähin kartoitettu vesi on Repojärvi, 1.6 km lounaaseen.

Spring european perch on Iso-Luoma hold shallow, usually 1 to 3.5 m. They move out to 2.5 to 8.5 m in summer and finish the year down in 3.5 to 10 m. Put Back-bay flat first on the milk run — a weed flat near 1 m that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Back-bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Break off the point (9.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (9.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (9.5 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 0.5 to 2.5 m. Summer is a 2.5 to 6 m game here, winter a 1.5 to 4.5 m one. Start at Shallow bay flat. It's a weed flat holding about 0.5 m of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Back-bay flat (1 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Secondary point (1.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Back-bay flat (1 m) | Tip-ups, Large jigging spoon |
Spring zander on Iso-Luoma hold shallow, usually 1 to 4.5 m. They move out to 4.5 to 11 m in summer and finish the year down in 6 to 12 m. Put Break off the point first on the milk run — a drop-off near 9.5 m that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a vertical softbait over humps or a deep crankbait.
| 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 | 4.5 to 11 m | dusk & dawn | Break off the point (9.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (9.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (9.5 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Start shallow in spring: lake whitefish sit in 4.5 to 14 m that time of year. Summer pushes them deeper, 4.5 to 15 m, and winter fish settle into 4.5 to 15 m. The spot to know is Deep basin, a deep basin in about 15 m of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
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 | 4.5 to 14 m | midday & dawn | Break off the point (9.5 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 (9.5 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 |
When the water first warms, burbot slide up into 4.5 to 15 m. There's no big seasonal slide here — summer means 4.5 to 15 m, winter 3.5 to 15 m. If you only fish one area, make it Deep basin: a deep basin around 15 m that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.

Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 15 m.

Iso-Luoma is about 49 ft (15 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-Luoma on syvimmillään noin 15 metriä (49 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Iso-Luoma. 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.
Back-bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for european perch 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 Iso-Luoma 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.
