31.9-acre lake in Mecklenburg-Vorpommern, Germany. The lake tops out around 12 m. 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:
Das Gewässer zeichnet 13 Hektar mit 2.6 km Ufer. Die Uferlinie ist mäßig gegliedert (Index 2) — genug Landzungen und Buchten zum Abfischen. Etwa 58% der Fläche sind flacher als ~5 m — dort leben Kraut und Beutefische. Von Ende zu Ende misst das Gewässer rund 1.1 km, an der breitesten Stelle 0.3 km. Das nächste kartierte Gewässer ist Schmiedegrundsee, 4.8 km Richtung Norden.

When the water first warms, european perch slide up into 1 to 3.5 m. Summer is a 2.5 to 8.5 m game here, winter a 3.5 to 10 m one. Start at Shallow bay flat. It's a weed flat holding about 1 m of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| Saison | Tiefe | Beste Zeit | Einstieg | Köder |
|---|---|---|---|---|
| Frühling | 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 2.5 to 8.5 m | dawn | Break off the point (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Herbst | 3 to 10 m | midday | Break off the point (6.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3.5 to 10 m | midday & dawn | Deep basin (11 m) | Tungsten jig + maggots, Small balance jig |
Spring northern pike on Demenzsee hold shallow, usually 0.5 to 2.5 m. They move out to 2.5 to 6 m in summer and finish the year down in 1.5 to 4.5 m. Put Shallow bay flat first on the milk run — a weed flat near 1 m that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Saison | Tiefe | Beste Zeit | Einstieg | Köder |

Anglers target european perch, northern pike on Demenzsee. 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.
Shallow bay flat is the top-rated area: a weed flat in about 4 ft of water that rates prime for european perch in spring. The map above holds the full rated-spot list for every 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.
Fishing on Demenzsee is regulated by the LALLF Mecklenburg-Vorpommern (Angelfischerei). Check the official Germany regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
