Fishing Grungstadvatnet: what the data says
1,630-acre lake in Norway. The lake tops out around 135 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
On the chart, Grungstadvatnet draws 1,626 acres inside 10.1 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. About 2% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.

Brown Trout fishing at Grungstadvatnet
Come spring, look for brown trout tight to the bank in 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. If you only fish one area, make it Main-lake point: a point around 29 ft that scores prime in fall. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.

|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Secondary point (27 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Main-lake point (29 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (29 ft) | Jerkbait over gravel, Casting spoon |

Tie on a blade bait vertical or a small jigging spoon and you're in the game.
