3,143-acre lake in Sweden. The lake tops out around 44 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.
Umnässjön mäter 1 269 hektar bakom 29.1 km strandlinje. Ett strandindex på 2.3 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 14% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 11.4 km vatten från ena änden till den andra och 2.9 km på bredden. Sjön ligger i Storuman kommun. Nedre Boksjön ligger 14.5 km åt norr — närmaste grannvatten på kartan.

Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Shallow bay flat is the standout, a feeding flat at roughly 2 m, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. 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 | Sharp break (6 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. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Summer european perch concentrate at Sharp break, a prime-rated drop-off around 6 m. Warm-month bites cluster around early morning. 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 | Sharp break (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Sharp break (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Offshore hump (4.5 m) | Tungsten jig + maggots, Small balance jig |
Early season brown trout use the shallows, holding in 1 to 7.5 m. Expect a summer slide to 7.5 to 18 m, then a winter hold in 1.5 to 11 m. Put Sharp break first on the milk run — a drop-off near 6 m that grades prime for winter. In summer the feeding windows fall in 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 | Sharp break (6 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommar | 7.5 to 18 m | night & dawn | Break off the point (20 m) | Spoon at the thermocline, Deep stickbait (night) |
| Höst | 1.5 to 9 m | dusk & dawn | Shoreline point (10 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Sharp break (6 m) | Jigging spoon, Small stickbait (slow) |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. Summer is a 12 to 27 m game here, winter a 7.5 to 21 m one. Start at Sharp break. It's a drop-off holding about 6 m of water and rates prime come spring. The feeding windows run 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 | Sharp break (6 m) | Small jig + waxworm, Blade bait (small) |
| Sommar | 12 to 27 m | dawn | Break off the point (20 m) | Blade bait vertical, Small jigging spoon |
| Höst | 2.5 to 9 m | dusk | Offshore hump (4.5 m) | Small spoon (gold), Jig + plastic larva |
| Vinter | 7.5 to 21 m | midday & dawn | Break off the point (20 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 7.5 to 21 m that time of year. Warm water sends them out to 15 to 37 m; cold water stacks them in 4.5 to 18 m. Top water on the chart: Offshore hump, an offshore hump in the 4.5 m range, prime in winter. Fish it in after dark and midday and you'll meet the bite. 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 (20 m) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Sommar | 15 to 37 m | night & midday | Deep basin (37 m) | Heavy jig + cut bait |
| Höst | 9 to 24 m | night & dusk | Break off the point (20 m) | Glow spoon + minnow head, Blade bait (slow) |
| Vinter | 4.5 to 18 m | night & dusk | Offshore hump (4.5 m) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 10 features, led in depth by Deep basin at roughly 37 m.

Umnässjön is about 144 ft (44 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.

Anglers target northern pike, european perch, brown trout, lake whitefish, burbot on Umnässjön. 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.
Offshore hump is the top-rated area: an offshore hump in about 15 ft of water that rates prime for burbot in winter. The map above holds the full rated-spot list for every species and season.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
