6,798-acre lake in Norway. The lake tops out around 29 m. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
På kartet dekker Førrevatn (Blåsjø) 2 748 hektar innenfor 130.7 km strandlinje. Strandlinjen er sterkt oppfliket (indeks 7) — viker og nes overalt, som mangedobler den fiskbare kanten. Omtrent 65% av flaten er grunnere enn ~5 m — der maten finnes. Fra ende til ende måler vannet omtrent 13 km, på det bredeste 9.7 km. Vannet ligger i Hjelmeland kommune. Nærmeste kartlagte vann er Sandsavatnet, 14.5 km mot nordvest.

When the water first warms, brown trout slide up into 1 to 7.5 m. By summer they slide out to 7.5 to 18 m, and by winter most fish are in 1.5 to 11 m. If you only fish one area, make it Sharp break: a drop-off around 11 m that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 7.5 m | dawn & dusk | Shoreline point (1 m) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Sommer | 7.5 to 18 m | night & dawn | Sharp break (11 m) | Spoon at the thermocline, Deep stickbait (night) |
| Høst | 1.5 to 9 m | dusk & dawn | Shoreline point (1 m) | Jerkbait over gravel, Casting spoon |
| Vinter | 1.5 to 11 m | dawn | Break off the point (6 m) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. The spot to know is Break off the point, a drop-off in about 6 m of water that rates prime for european perch in summer. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | Shallow bay flat (0.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Break off the point (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Høst | 3 to 10 m | midday | Break off the point (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Break off the point (6 m) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 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. The spot to know is Shallow bay flat, a weed flat in about 0.5 m of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommer | 2.5 to 6 m | dawn & dusk | Break off the point (6 m) | Bucktail, Weedless spoon over cabbage |
| Høst | 2 to 5.5 m | midday & dawn | Sharp break (2.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shallow bay flat (0.5 m) | Tip-ups, Large jigging spoon |
Spring lake whitefish on Førrevatn (Blåsjø) hold shallow, usually 4.5 to 14 m. They move out to 12 to 27 m in summer and finish the year down in 7.5 to 21 m. Put Deep basin first on the milk run — a deep basin near 20 m that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

| Vår | 4.5 to 14 m | midday & dawn | Break off the point (6 m) | Small jig + waxworm, Blade bait (small) |

Spring arctic char on Førrevatn (Blåsjø) hold shallow, usually 1 to 4.5 m. They move out to 6 to 18 m in summer and finish the year down in 3 to 12 m. Put Deep basin first on the milk run — a deep basin near 20 m that grades prime for summer. The feeding windows run early morning. The summer box starts with a jigging spoon vertical or a tube jig (smelt).
| Sesong | Dybde | Beste tid | Start ved | Agn |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | midday & dawn | Sharp break (1 m) | Small casting spoon (silver/orange), Jerkbait (small) |
