34,409-acre lake near Brouwershaven. The water tops out around 146 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 34,275 acres wrapped in 56.4 miles of bank. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. About 47% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 14.5 mi, about 9.6 mi across. If the bite dies, Goeree Coast is 8 mi to the northwest.
Vis- en dieptekaart van Grevelingenmeer, Nederland: gemeten dieptelijnen (Rijkswaterstaat) tot 45 m, met visstekken voor haring, bot, geep.

Come spring, look for atlantic herring tight to the bank in 5 to 25 ft. They move out to 15 to 50 ft in summer and finish the year down in 20 to 60 ft. If you only fish one area, make it Measured coastal depth break: a drop-off around 8 ft that scores prime in fall. Best bite is early morning and the evening. A herring feather rig or a small silver jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Measured shallow feeding flat (8 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Measured coastal depth break (8 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Measured coastal depth break (8 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Measured deep-water holding area (146 ft) | Small silver jig, Sparse feather rig |
Start shallow in spring: european flounder sit in 5 to 25 ft that time of year. Warm water sends them out to 6 to 35 ft; cold water stacks them in 15 to 50 ft. Top water on the chart: Measured shallow feeding flat, a feeding flat in the 8 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bottom jig with spinner blade until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Measured shallow feeding flat (8 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Measured shallow feeding flat (8 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Measured coastal depth break (8 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Measured coastal depth break (8 ft) | Small bottom jig |
Come spring, look for garfish tight to the bank in 1 to 15 ft. Expect a summer slide to 2 to 20 ft, then a winter hold in 20 to 60 ft. Start at Measured coastal depth break. It's a drop-off holding about 8 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A slim casting spoon or a surface-skipping fly is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | open water | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Measured coastal depth break (8 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Measured coastal depth break (8 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | open water |
