Fishing Onilsavatnet: what the data says
168-acre lake in Norway. The lake tops out around 131 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. What the data behind the map says about each species, season by season:
The drawn water covers 168 acres wrapped in 2.9 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. 8% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.

Brown Trout fishing at Onilsavatnet
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 25 to 60 ft before dropping to 5 to 35 ft for winter. The spot to know is Secondary point, a point in about 6 ft of water that rates prime for brown trout in spring. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Secondary point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Main-lake point (27 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (27 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
European Perch fishing at Onilsavatnet
Come spring, look for european perch tight to the bank in 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. If you only fish one area, make it Back-bay flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (5 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (18 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (125 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Shallow bay flat (18 ft) | Tungsten jig + maggots, Small balance jig |
Northern Pike fishing at Onilsavatnet
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Back-bay flat — weed flat, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |

| Winter | 5 to 15 ft | midday | Back-bay flat (5 ft) | Tip-ups, Large jigging spoon |
Lake Whitefish fishing at Onilsavatnet
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. Shallow feeding flat is the standout, a feeding flat at roughly 32 ft, rated prime for spring lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (32 ft) | Small jig + waxworm, Blade bait (small) |
