2,768-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. Below is the species-by-species picture, pulled from the same data the map uses.
Kartalla Iso-Naakkima kattaa 1 144 hehtaaria, rantaviivaa 22.5 km. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.9). Noin 58% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 5 km, leveimmillään 3.4 km. Vesi sijaitsee alueella Pieksämäen seutukunta. Lähin kartoitettu vesi on Pieni-Naakkima, 1.6 km koilliseen.

Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for european perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| 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 | Break off the point (3.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (3.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (3.5 m) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. Midsummer fish sit out in 2.5 to 6 m before dropping to 1.5 to 4.5 m for winter. The spot to know is Shallow bay flat, a weed flat in about 1 m of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

|---|---|---|---|---|
| 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 | Weed flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Break off the point (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2 m) | Tip-ups, Large jigging spoon |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. The spot to know is Break off the point, a drop-off in about 3.5 m of water that rates prime for zander in fall. Warm-month bites cluster around the evening and early morning. Throw a vertical softbait over humps or a deep crankbait until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (0.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (3.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (3.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Deep basin (15 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Spring lake whitefish on Iso-Naakkima hold shallow, usually 4.5 to 14 m. They move out to 4.5 to 15 m in summer and finish the year down in 4.5 to 15 m. Put Deep basin first on the milk run — a deep basin near 15 m that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

| Kevät | 4.5 to 14 m | midday & dawn | Shallow feeding flat (6 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 (3.5 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 |
In spring, burbot run shallow here, mostly 4.5 to 15 m. Summer keeps them at 4.5 to 15 m, and they winter in 3.5 to 15 m. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 15 m. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.

Iso-Naakkima 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.

Anglers target european perch, northern pike, zander, lake whitefish, burbot on Iso-Naakkima. 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. 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-Naakkima 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.
