464-acre lake in Sweden. The lake tops out around 53 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. The rest of this page walks each species through its year, using the map's own scoring.
Lilla Ullfjärden mäter 187 hektar bakom 8.5 km strandlinje. Strandlinjen är måttligt strukturerad (index 1.8) — tillräckligt med uddar och vikar att fiska av. Ungefär 19% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 3.9 km vatten från ena änden till den andra och 1 km på bredden. Sjön ligger i Upplands-Bro kommun. Lejondalssjön ligger 11.3 km åt sydost — närmaste grannvatten på kartan.

Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Spring northern pike concentrate at Shallow bay flat, a prime-rated feeding flat around 2 m. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| 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 |
Spring puts european perch in skinny water — 1 to 3.5 m is the zone. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Shallow bay flat is the standout, a feeding flat at roughly 2 m, rated prime for spring european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| 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 | open water | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Early season brown trout use the shallows, holding in 1 to 7.5 m. Summer is a 7.5 to 18 m game here, winter a 1.5 to 11 m one. The chart's best answer is Main-lake point — point, 13 m, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | open water | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Main-lake point (13 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | open water | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | open water | Jigging spoon, Small stickbait (slow) |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. By summer they slide out to 12 to 27 m, and by winter most fish are in 7.5 to 21 m. If you only fish one area, make it Break off the point: a drop-off around 24 m that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 4.5 to 14 m | midday & dawn | Shallow bay flat (2 m) | Small jig + waxworm, Blade bait (small) |
| Sommar | 12 to 27 m | dawn | Break off the point (24 m) | Blade bait vertical, Small jigging spoon |
| Höst | 2.5 to 9 m | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Break off the point (24 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 7.5 to 21 m that time of year. Summer pushes them deeper, 15 to 37 m, and winter fish settle into 4.5 to 18 m. The spot to know is Break off the point, a drop-off in about 24 m of water that rates prime for burbot in fall. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 7.5 to 21 m | night & dusk | Break off the point (24 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Break off the point (24 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Break off the point (24 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | open water | Glow tungsten + cut bait, Rattle spoon + minnow head |
Early season european smelt use the shallows, holding in 1 to 7.5 m. Expect a summer slide to 7.5 to 21 m, then a winter hold in 6 to 20 m. Put Break off the point first on the milk run — a drop-off near 24 m that grades good for summer. In summer the feeding windows fall in early morning and the evening. Tie on a tiny vertical spoon or a micro jig and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | night & dusk | open water | Micro silver jig, Tiny feather rig |
| Sommar | 7.5 to 21 m | dawn & dusk | Break off the point (24 m) | Tiny vertical spoon, Micro jig |
| Höst | 4.5 to 17 m | dusk | open water | Micro jig, Tiny silver spoon |
| Vinter | 6 to 20 m | dusk | open water | Tiny glow jig, Micro ice spoon |
