33,316-acre Guldborg Sound. North Denmark saltwater fishing map with official Danish Geodata Agency 50 m bathymetry, measured-only fishing spots, DTU-supported fish targets, seasonal forage guidance and public shore-access context. Northern Guldborg Sound's constricted current corridor and shallow adjoining bays. The water tops out around 51 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
The outline encloses 33,335 acres, worked by 58.2 miles of shoreline. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 41% of the surface — that's where the groceries are. Tip to tip the water measures near 15.6 mi with an 8.7-mi widest point. If the bite dies, Karrebæk Fjord is 12 mi to the northwest.
The target roster combines the named DTU monitoring area with conservative habitat-compatible Danish regional records. It documents observed or regionally supported occurrence, not equal abundance, a catch rate, or a promised catch in this child. European eel is omitted because recreational eel fishing is currently closed. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Spring sea trout on Guldborg Sound - North hold shallow, usually 3 to 20 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 5 to 30 ft. The chart's best answer is Shoreline point — point, 4 ft, good for spring. Prime time lands in early morning and the evening. The summer box starts with a deep-running wobbler or a trolled spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shoreline point (4 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | DDM measured channel edge (25 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | Shoreline point (4 ft) | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | Sharp break (8 ft) | Slow coastal spoon, Suspending wobbler |
Early season atlantic herring use the shallows, holding in 5 to 25 ft. Summer is a 15 to 50 ft game here, winter a 15 to 51 ft one. The chart's best answer is Deepest basin — deep basin, 50 ft, prime for summer. Best bite is early morning and the evening. Tie on a herring feather rig or a small silver jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | DDM measured current seam (21 ft) | Small herring feather rig, Micro jig rig |

| Fall | 10 to 40 ft | dawn & dusk | DDM measured current seam (21 ft) | Small feather rig, Compact silver spoon |
| Winter | 15 to 51 ft | midday | Deepest basin (50 ft) | Small silver jig, Sparse feather rig |
In spring, european flounder run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 6 to 35 ft before dropping to 15 to 50 ft for winter. Spring european flounder concentrate at Feeding flat, a prime-rated feeding flat around 17 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom jig with spinner blade most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Feeding flat (17 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (17 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Sharp break (8 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Deepest basin (50 ft) | Small bottom jig |
Spring garfish on Guldborg Sound - North hold shallow, usually 1 to 15 ft. By summer they slide out to 2 to 20 ft, and by winter most fish are in 15 to 51 ft. The chart's best answer is Shoreline point — point, 4 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a slim casting spoon or a surface-skipping fly.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (4 ft) | Slim silver spoon, Small inline spinner |

| Fall | 8 to 30 ft | dawn & dusk | DDM measured current seam (21 ft) | Weighted slim spoon, Small silver jig |
| Winter | 15 to 51 ft | midday | Deepest basin (50 ft) |
When the water first warms, european plaice slide up into 8 to 35 ft. Summer is a 6 to 40 ft game here, winter a 15 to 51 ft one. Start at Feeding flat. It's a feeding flat holding about 17 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a light spooned bottom rig or a beaded trace rigged through the warm months.

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (Denmark). Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for Denmark waters are set by the Danish Agency for Green Transition and Aquatic Environment (current recreational fishing rules) — and special regulations can apply to Guldborg Sound - North specifically, so confirm the current rules before you fish. Most anglers using light hand gear need the applicable Danish angling licence, subject to the official age exemptions. Check live species rules, the mapped and unmapped 500-metre stream-mouth conservation belts, local fishing rights, protected areas and posted shore access before every trip. Recreational European eel fishing is currently prohibited, so eel is not promoted as a target here.

Guldborg Sound - North is about 51 ft (16 m) deep at its deepest point. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.

The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Deepest basin is the top-rated area: a deep basin in about 50 ft of water that rates prime for atlantic herring in summer. The map above holds the full rated-spot list for every species and season.
For sea trout, 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.
