499-acre reservoir in Switzerland. The lake tops out around 220 ft. The depth chart comes from Federal Office of Topography swisstopo (swissBATHY3D) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Drawn out, this is 499 acres of water rimmed by 6.1 miles of bank. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. About 6% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2.3 mi long by 0.6 mi wide at the broadest reach. Closest neighbour on DepthScout: Lake Sarnen, 5 mi northeast of here.
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 12 to 33 ft. The spot to know is Shallow bay flat, a feeding flat in about 1 ft of water that rates prime for european perch in spring. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (1 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 1 ft 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (1 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Spring lake whitefish on Lake Lungern hold shallow, usually 15 to 45 ft. They move out to 40 to 90 ft in summer and finish the year down in 25 to 70 ft. Put Feeding flat first on the milk run — a feeding flat near 54 ft that grades good for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Feeding flat (54 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Feeding flat (54 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Feeding flat (54 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, brown trout slide up into 3 to 25 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 5 to 35 ft. If you only fish one area, make it Main-lake point: a point around 1 ft that scores prime in spring. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | open water | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (1 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
Spring arctic char on Lake Lungern hold shallow, usually 4 to 15 ft. They move out to 20 to 60 ft in summer and finish the year down in 10 to 40 ft. Put Shallow bay flat first on the milk run — a feeding flat near 1 ft that grades good for spring. The feeding windows run early morning. The summer box starts with a jigging spoon vertical or a tube jig (smelt).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | open water | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | open water | Jigging spoon (glow/silver), Tungsten jig + plastic |
Lake Lungern carries 7 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 220 ft down.
Season dates, license requirements, and size and bag limits for Switzerland waters are set by the Federal Office for the Environment (federal framework; licences and rules are cantonal) — and special regulations can apply to Lake Lungern specifically, so confirm the current rules before you fish.

Lake Lungern is about 220 ft (67 m) deep at its deepest point. The depth chart comes from Federal Office of Topography swisstopo (swissBATHY3D) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target european perch, northern pike, lake whitefish, brown trout, arctic char on Lake Lungern.
Shallow bay flat is the top-rated area: a feeding flat in about 1 ft of water that rates prime for northern pike in spring. Scroll up to the map for the complete spot list by species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
