265,144-acre lake near Enköping. The lake tops out around 64 m. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
På kartan täcker Mälaren 106 218 hektar innanför 2624.5 km strandlinje, uppbruten av 820 öar. Ett strandindex på 22.7 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 60% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 116.7 km vatten från ena änden till den andra och 67.1 km på bredden. Sjön ligger i Strängnäs kommun. Lilla Ullfjärden ligger 29 km åt öster — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Mälaren, Sverige: ungefärliga djupkurvor ner till 64 m (210 fot), och de bästa fiskeplatserna för gädda, abborre, gös med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
In spring, northern pike run shallow here, mostly 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. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (2 m) | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Feeding flat (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Shallow bay flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (2 m) | Tip-ups, Large jigging spoon |
In spring, european perch run shallow here, mostly 1 to 3.5 m. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. Shallow bay flat is the standout, a weed flat at roughly 2 m, rated prime for spring european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 2.5 to 8.5 m | dawn | Offshore hump (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Offshore hump (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Offshore hump (6 m) | Tungsten jig + maggots, Small balance jig |
In spring, zander run shallow here, mostly 1 to 4.5 m. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. Örsundaån inflow is the standout, an inflow / creek mouth at roughly 2.5 m, rated prime for spring zander. Time it for the evening and early morning. You won't need more than a vertical softbait over humps or a deep crankbait most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | Örsundaån inflow (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Offshore hump (6 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Shoreline point (3.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Offshore hump (8 m) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: burbot in 7.5 to 21 m. Midsummer fish sit out in 15 to 37 m before dropping to 4.5 to 18 m for winter. The spot to know is Offshore hump, an offshore hump in about 6 m of water that rates prime for burbot in winter. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Offshore hump (8 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Deep hole (42 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Offshore hump (8.5 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Offshore hump (6 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Come spring, look for european grayling tight to the bank in 0.5 to 3 m. They move out to 1 to 4.5 m in summer and finish the year down in 2.5 to 7.5 m. If you only fish one area, make it Örsundaån inflow: an inflow / creek mouth around 2.5 m that scores prime in spring. Best bite is the evening and early morning. A dry fly (caddis, terrestrial) or a nymph under an indicator is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 3 m | midday & dusk | Örsundaån inflow (2.5 m) | Small dry fly (midge, olive), Inline spinner #0-1 |
| Sommar | 1 to 4.5 m | dusk & dawn | Örsundaån inflow (2.5 m) | Dry fly (caddis, terrestrial), Nymph under an indicator |
| Höst | 2 to 6 m | midday | Örsundaån inflow (2.5 m) | Weighted nymph, Small spoon (copper) |
| Vinter | 2.5 to 7.5 m | midday & dawn | Offshore hump (6 m) | Tiny jig + maggot, Small mormyshka |
