6,419-acre lake in Finland. The lake tops out around 30 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.
Kartalla Juolasvesi-Sarkavesi kattaa 2 739 hehtaaria, rantaviivaa 110.2 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 5.9) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 47% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 20.6 km, leveimmillään 6 km. Vesi sijaitsee alueella Mikkelin seutukunta. Lähin kartoitettu vesi on Nurmaanjärvi, 8 km lounaaseen.

In spring, european perch run shallow here, mostly 1 to 3.5 m. Midsummer fish sit out in 2.5 to 8.5 m before dropping to 3.5 to 10 m for winter. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 1.5 m. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (1.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (4.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (4.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Sharp break (4.5 m) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 0.5 to 2.5 m. Summer pushes them deeper, 2.5 to 6 m, and winter fish settle into 1.5 to 4.5 m. Shallow bay flat is the standout, a weed flat at roughly 1.5 m, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Sharp break (4.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Back-bay flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (1.5 m) | Tip-ups, Large jigging spoon |
In spring, zander run shallow here, mostly 1 to 4.5 m. Midsummer fish sit out in 4.5 to 11 m before dropping to 6 to 12 m for winter. Fall zander concentrate at Sharp break, a prime-rated drop-off around 4.5 m. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a vertical softbait over humps or a deep crankbait most summer days.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (2 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Sharp break (4.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Sharp break (4.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (13 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Come spring, look for lake whitefish tight to the bank in 4.5 to 14 m. Expect a summer slide to 12 to 27 m, then a winter hold in 7.5 to 21 m. Start at Deep basin. It's a deep basin holding about 27 m of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Break off the point (13 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Deep basin (27 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Rock reef (2 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Break off the point (13 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: burbot in 7.5 to 21 m. As the season builds they drop to 9 to 30 m, wintering in 4.5 to 18 m. Top water on the chart: Deep basin, a deep basin in the 27 m range, prime in summer. Time it for after dark and midday. Summer baits: a heavy jig + cut bait gets it done.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 7.5 to 21 m | night & dusk | Break off the point (13 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 9 to 30 m | night & midday | Deep basin (27 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Break off the point (13 m) | Glow spoon + minnow head, Blade bait (slow) |
| Talvi | 4.5 to 18 m | night & dusk | Rock reef (2 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
14 pieces of structure are mapped here — Deep basin, around 27 m, is the deepest of them.

Anglers target european perch, northern pike, zander, lake whitefish, burbot on Juolasvesi-Sarkavesi. 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 5 ft of water that rates prime for european perch in spring. The map above holds the full rated-spot list for every 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 Juolasvesi-Sarkavesi 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.
