1,504-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. The season-by-season read for each species follows, from the map's own numbers.
Vesi piirtyy 635 hehtaarin laajuisena, rantaa 25.6 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.9) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 38% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 5.3 km, leveimmillään 3.4 km. Vesi sijaitsee alueella Mikkelin seutukunta. Lähin kartoitettu vesi on Ala-Kuhanen, 4.8 km koilliseen.

Spring european perch on Herajärvi 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 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. 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 | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow feeding flat (9 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 |
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 1 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 (1 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Main-lake point (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Main-lake point (2.5 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 |
Spring zander on Herajärvi 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 Main-lake point first on the milk run — a point near 2.5 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 (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Shallow feeding flat (9 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Main-lake point (2.5 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 |
Start shallow in spring: lake whitefish sit in 4.5 to 14 m that time of year. Summer pushes them deeper, 12 to 27 m, and winter fish settle into 7.5 to 21 m. The spot to know is Break off the point, a drop-off 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.
| 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 (15 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Main-lake point (2.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (15 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, burbot slide up into 7.5 to 21 m. By summer they slide out to 11 to 35 m, and by winter most fish are in 4.5 to 18 m. If you only fish one area, make it Deep basin: a deep basin around 35 m that scores prime in summer. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
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 (15 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 (35 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Break off the point (15 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Break off the point (15 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
7 pieces of structure are mapped here — Deep basin, around 35 m, is the deepest of them.

Herajärvi 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.
Herajärvi on syvimmillään noin 35 metriä (115 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Herajärvi. 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 3 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.
