89,314-acre river near Zierikzee. The water tops out around 115 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. Every species below gets its seasonal read from the same numbers driving the chart.
Shoreline on the chart totals NaN miles — one island included. Index NaN on the shoreline: a few honest points and pockets, nothing labyrinthine. About NaN% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The nearest mapped water is Kanaal door Zuid-Beveland, 5 mi to the southeast.

In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 20 to 60 ft for winter. Spring atlantic herring concentrate at Measured shallow feeding flat, a good-rated feeding flat around 9 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a herring feather rig or a small silver jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Measured shallow feeding flat (9 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Measured coastal depth break (4 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Measured coastal depth break (4 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Measured coastal depth break (4 ft) | Small silver jig, Sparse feather rig |
Early season european flounder use the shallows, holding in 5 to 25 ft. Summer is a 6 to 35 ft game here, winter a 15 to 50 ft one. The chart's best answer is Measured shallow feeding flat — feeding flat, 9 ft, prime for spring. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Measured shallow feeding flat (9 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Measured shallow feeding flat (30 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Measured shallow feeding flat (30 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Measured shallow feeding flat (30 ft) | Small bottom jig |
The spring pattern is a shallow one: garfish in 1 to 15 ft. Midsummer fish sit out in 2 to 20 ft before dropping to 20 to 60 ft for winter. The spot to know is Measured coastal depth break, a drop-off in about 4 ft of water that rates good for garfish in fall. Plan around early morning and the evening in the warm months. Summer baits: a slim casting spoon or a surface-skipping fly gets it done.
| 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 (4 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Measured coastal depth break (4 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | open water |
