154.1-acre lake in Brandenburg, Germany. The lake tops out around 4.5 m. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Auf der Karte umfasst Großer Gruminsee 62 Hektar hinter 3.2 km Uferlinie. Das Becken ist einfach (Uferindex 1.1) — fast eine Schüssel, die Tiefenlinien zählen mehr als das Ufer. Von Ende zu Ende misst das Gewässer rund 1.1 km, an der breitesten Stelle 0.8 km. Das nächste kartierte Gewässer ist Grimnitzsee, 3.2 km Richtung Südwesten.

Early season common bream use the shallows, holding in 1 to 4.5 m. Summer is a 1.5 to 4.5 m game here, winter a 1.5 to 4.5 m one. The chart's best answer is Deep basin — deep basin, 4.5 m, prime for fall. Best bite is early morning and the evening.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Tiefe | Beste Zeit | Einstieg | Köder |
|---|---|---|---|---|
| Frühling | 1 to 4.5 m | dusk | Back-bay flat (1 m) | |
| Sommer | 1.5 to 4.5 m chart-limited; documented 2.5 to 7.5 m | dawn & dusk | Break off the point (3.5 m) | |
| Herbst | 1.5 to 4.5 m chart-limited; documented 3.5 to 11 m | midday | Deep basin (4.5 m) | |
| Winter | 1.5 to 4.5 m chart-limited; documented 5.5 to 14 m | midday | Deep basin (4.5 m) |
Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Warm water sends them out to 1 to 4.5 m; cold water stacks them in 1.5 to 4.5 m. Top water on the chart: Back-bay flat, a weed flat in the 1 m range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.

| Saison | Tiefe | Beste Zeit | Einstieg | Köder |
|---|---|---|---|---|
| Frühling | 1 to 3.5 m | midday & dawn | Back-bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Sommer | 1 to 4.5 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (4.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Herbst | 1.5 to 4.5 m chart-limited; documented 3 to 10 m | midday | Deep basin (4.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 1.5 to 4.5 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (4.5 m) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. As the season builds they drop to 1.5 to 4.5 m, wintering in 1.5 to 4.5 m. Top water on the chart: Shallow bay flat, a weed flat in the 0.5 m range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

| Saison | Tiefe | Beste Zeit | Einstieg | Köder |
|---|---|---|---|---|
| Frühling | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Sommer | 1.5 to 4.5 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Break off the point (3.5 m) | Bucktail, Weedless spoon over cabbage |
| Herbst | 1.5 to 4.5 m chart-limited; documented 2 to 5.5 m | midday & dawn | Break off the point (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 1.5 to 4.5 m | midday | Back-bay flat (1 m) | Tip-ups, Large jigging spoon |
Spring roach on Großer Gruminsee hold shallow, usually 0.5 to 3 m. By summer they slide out to 1 to 4.5 m, and by winter most fish are in 1.5 to 4.5 m. The chart's best answer is Shallow bay flat — weed flat, 0.5 m, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a tiny spoon or a micro jig.

| Saison | Tiefe | Beste Zeit | Einstieg | Köder |
|---|---|---|---|---|
| Frühling | 0.5 to 3 m | midday & dusk | Shallow bay flat (0.5 m) | Micro jig under a float |
| Sommer | 1 to 4.5 m chart-limited; documented 1 to 5.5 m | dawn & dusk | Back-bay flat (1 m) | Tiny spoon, Micro jig |
| Herbst | 1 to 4.5 m chart-limited; documented 2.5 to 8.5 m | midday | Break off the point (3.5 m) | Tiny jig, Small silver spoon |
| Winter | 1.5 to 4.5 m chart-limited; documented 3.5 to 11 m | midday | Deep basin (4.5 m) | Tungsten mormyshka |
Come spring, look for rudd tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 0.5 to 3.5 m, then a winter hold in 1.5 to 4.5 m. Start at Shallow bay flat. It's a weed flat holding about 0.5 m of water and rates prime come spring. Prime time lands in early morning and the evening. A tiny surface fly or a micro spoon is the honest summer answer here.

| Frühling | 0.5 to 2.5 m | midday & dusk | Shallow bay flat (0.5 m) | Micro jig, Tiny dry fly |

| Winter | 1.5 to 4.5 m chart-limited; documented 3.5 to 9 m | midday | Deep basin (4.5 m) | Tiny mormyshka |
Start shallow in spring: ruffe sit in 1 to 4.5 m that time of year. They don't go far with the seasons — 1.5 to 4.5 m covers summer, 1.5 to 4.5 m covers winter. The spot to know is Deep basin, a deep basin in about 4.5 m of water that rates prime for ruffe in summer. Warm-month bites cluster around early morning and the evening. Throw a micro jig until the fish tell you otherwise.

Großer Gruminsee is about 15 ft (5 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Großer Gruminsee ist an der tiefsten Stelle etwa 5 Meter (15 Fuß) tief. Die Tiefen stammen aus echten Vermessungen.
Anglers target common bream, european perch, northern pike, roach, rudd, ruffe, tench, wels catfish on Großer Gruminsee.
Deep basin is the top-rated area: a deep basin in about 14 ft of water that rates prime for common bream in fall. Every other rated spot, per species and season, is on the map above.
For common bream, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
