21,799-acre lake near Lohja. The largest lake in Uusimaa, west of Helsinki. A clear, deep, 30-plus-species water best known for its strong zander fishing. The lake tops out around 52 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.
Vesi piirtyy 8 837 hehtaarin laajuisena, rantaa 313.7 km, ja saaria on 82. Rantaviiva on voimakkaasti rikkonainen (indeksi 9.4) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 33% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 22 km, leveimmillään 13.7 km. Vesi sijaitsee alueella Helsinki sub-region. Lähin kartoitettu vesi on Hormajärvi, 8 km koilliseen.

When the water first warms, zander slide up into 1 to 4.5 m. By summer they slide out to 4.5 to 11 m, and by winter most fish are in 6 to 12 m. If you only fish one area, make it Rock reef: a rock pile around 2 m that scores prime in spring. In summer the feeding windows fall in the evening and early morning. Keep a vertical softbait over humps or a deep crankbait rigged through the warm months.
| 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 | Main-lake point (4 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Main-lake point (4 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Deep basin (52 m) | Vertical jig / mormyshka with bait, Slow blade bait |
Spring northern pike on Lohjanjärvi hold shallow, usually 0.5 to 2.5 m. By summer they slide out to 2.5 to 6 m, and by winter most fish are in 1.5 to 4.5 m. The chart's best answer is Back-bay flat — weed flat, 0.5 m, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Back-bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Shallow flat (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Shallow flat (2.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow flat (2.5 m) | Tip-ups, Large jigging spoon |
When the water first warms, european perch slide up into 1 to 3.5 m. By summer they slide out to 2.5 to 8.5 m, and by winter most fish are in 3.5 to 10 m. If you only fish one area, make it Shallow flat: a weed flat around 2.5 m that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow flat (2.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow flat (2.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Deep basin (52 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Feeding flat (7.5 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: brown trout sit in 1 to 7.5 m that time of year. Summer pushes them deeper, 7.5 to 18 m, and winter fish settle into 1.5 to 11 m. The spot to know is Main-lake point, a point in about 4 m of water that rates prime for brown trout in spring. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 7.5 m | dawn & dusk | Main-lake point (4 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Kesä | 7.5 to 18 m | night & dawn | Main-lake point (4 m) | Spoon at the thermocline, Deep stickbait (night) |
| Syksy | 1.5 to 9 m | dusk & dawn | Rock reef (2 m) | Jerkbait over gravel, Casting spoon |
| Talvi | 1.5 to 11 m | dawn | open water | Jigging spoon, Small stickbait (slow) |
Spring puts lake whitefish in skinny water — 4.5 to 14 m is the zone. Warm water sends them out to 12 to 27 m; cold water stacks them in 7.5 to 21 m. Rock reef is the standout, a rock pile at roughly 2 m, rated prime for fall lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Feeding flat (7.5 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 12 to 27 m | dawn | Shallow bay flat (22 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 | Feeding flat (7.5 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 7.5 to 21 m. Summer is a 15 to 37 m game here, winter a 4.5 to 18 m one. The chart's best answer is Rock reef — rock pile, 2 m, prime for winter. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

|---|---|---|---|---|
| Kevät | 7.5 to 21 m | night & dusk | Deep basin (52 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Kesä | 15 to 37 m | night & midday | Deep basin (52 m) | Heavy jig + cut bait |
| Syksy | 9 to 24 m | night & dusk | Rock reef (2 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 |
