961-acre lake near Köping. The lake tops out around 23 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. Here's the year, species by species, as the scoring engine sees it.
På kartan täcker Iresjön 401 hektar innanför 26.7 km strandlinje, uppbruten av 5 öar. Ett strandindex på 3.8 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 59% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 4.7 km vatten från ena änden till den andra och 3.7 km på bredden. Sjön ligger i Lindesberg kommun. Svarttjärnen ligger 1.6 km åt sydost — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Iresjön, Sverige: ungefärliga djupkurvor ner till 23 m (77 fot), och de bästa fiskeplatserna för gädda, abborre och lake. 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 | Shallow bay flat (2 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 | Shallow bay flat (2 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Break off the point (11 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (11 m) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: burbot in 7.5 to 21 m. Midsummer fish sit out in 7 to 23 m before dropping to 4.5 to 18 m for winter. The spot to know is Deep basin, a deep basin in about 20 m of water that rates prime for burbot in spring. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Deep basin (20 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 7 to 23 m chart-limited; documented 15 to 37 m | night & midday | Deep basin (20 m) | Heavy jig + cut bait |
| Höst | 7 to 23 m chart-limited; documented 9 to 24 m | night & dusk | Deep basin (20 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Deep basin (20 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 20 m.
