8,196-acre lake near Joroinen. A humic Vuoksi-system lake at Joroinen. Pike, perch and zander water with stocked lake trout. The lake tops out around 17 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.
Kartalla Sysmä kattaa 3 138 hehtaaria, rantaviivaa 118.6 km, ja saaria on 78. Rantaviiva on voimakkaasti rikkonainen (indeksi 6) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 64% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 18.8 km, leveimmillään 4.3 km. Vesi sijaitsee alueella Pieksämäen seutukunta. Lähin kartoitettu vesi on Jokijärvi, 4.8 km koilliseen.

The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| 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 | Weed flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Weed flat (2 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: european perch sit in 1 to 3.5 m that time of year. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Top water on the chart: Shallow bay flat, a weed flat in the 1 m range, prime in spring. Fish it in early morning and you'll meet the bite. 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 | Weed flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Deep basin (13 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Shallow feeding flat (6 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Warm water sends them out to 4.5 to 11 m; cold water stacks them in 6 to 12 m. Top water on the chart: Deep basin, a deep basin in the 13 m range, prime in winter. Fish it in the evening and early morning and you'll meet the bite. 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 (1 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Shallow feeding flat (6 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Deep basin (13 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Deep basin (13 m) | Vertical jig / mormyshka with bait, Slow blade bait |
When the water first warms, brown trout slide up into 1 to 7.5 m. Summer is a 5 to 17 m game here, winter a 1.5 to 11 m one. Start at Deep basin. It's a deep basin holding about 13 m of water and rates prime come summer. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 7.5 m | dawn & dusk | Secondary point (2 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Kesä | 5 to 17 m | night & dawn | Deep basin (13 m) | Spoon at the thermocline, Deep stickbait (night) |
| Syksy | 1.5 to 9 m | dusk & dawn | Secondary point (2 m) | Jerkbait over gravel, Casting spoon |
| Talvi | 1.5 to 11 m | dawn | Deep basin (13 m) | Jigging spoon, Small stickbait (slow) |
