2,797-acre river near Ameland. The water tops out around 132 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 rest of this page walks each species through its year, using the map's own scoring.
On the chart, Borndiep Offshore draws 2,797 acres inside 14.4 miles of shoreline, with a single island in the mix. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 63% of this chart. Tip to tip the water measures near 6 mi with a 2.2-mi widest point. For a second option, Terschelling Coast lies 7 mi southwest.

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. Summer atlantic herring concentrate at Measured coastal depth break, a prime-rated drop-off around 16 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 (5 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Measured coastal depth break (16 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Measured coastal depth break (16 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Measured coastal depth break (16 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, 5 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 (5 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Measured shallow feeding flat (33 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Measured coastal depth break (9 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Measured coastal depth break (16 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 9 ft of water that rates prime 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 (9 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Measured coastal depth break (9 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | Measured coastal depth break (16 ft) |
