86,356-acre Køge Bay. 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 Køge Bay from the Copenhagen approaches toward the middle bay, with sand bars, harbor edges and Oresund exchange. The water tops out around 52 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Køge Bay - North runs 86,333 acres with 56.9 miles of edge. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 15% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 18.2 mi of water from one end to the other, 13.7 mi at the beam. Closest neighbour on DepthScout: Køge Bay - Middle, 8 mi south of here.
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 puts sea trout in skinny water — 3 to 20 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 5 to 30 ft. DDM source-backed depth reference (32 ft) is the standout, a drop-off at roughly 32 ft, rated prime for summer sea trout. Plan around early morning and the evening in the warm months. A deep-running wobbler or a trolled spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | DDM source-backed depth reference (16 ft) (16 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | DDM source-backed depth reference (32 ft) (32 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | DDM source-backed depth reference (16 ft) (16 ft) | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | DDM source-backed depth reference (16 ft) (16 ft) | Slow coastal spoon, Suspending wobbler |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Warm water sends them out to 15 to 50 ft; cold water stacks them in 16 to 52 ft. Top water on the chart: Deepest basin, a deep basin in the 52 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a herring feather rig or a small silver jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | DDM source-backed depth reference (22 ft) (22 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Deepest basin (52 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | DDM source-backed depth reference (22 ft) (22 ft) | Small feather rig, Compact silver spoon |
| Winter | 16 to 52 ft | midday | Deepest basin (52 ft) | Small silver jig, Sparse feather rig |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. If you only fish one area, make it DDM source-backed depth reference (7 ft): a feeding flat around 7 ft that scores prime in spring. Best bite is early morning and the evening. A bottom jig with spinner blade is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | DDM source-backed depth reference (7 ft) (7 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | DDM source-backed depth reference (7 ft) (7 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | DDM source-backed depth reference (32 ft) (32 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Deepest basin (52 ft) | Small bottom jig |
Spring puts garfish in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 2 to 20 ft; cold water stacks them in 16 to 52 ft. DDM source-backed depth reference (11 ft) is the standout, a gravel shoal at roughly 11 ft, rated prime for spring garfish. Plan around early morning and the evening in the warm months. A slim casting spoon or a surface-skipping fly covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | DDM source-backed depth reference (11 ft) (11 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | DDM source-backed depth reference (16 ft) (16 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | DDM source-backed depth reference (22 ft) (22 ft) | Weighted slim spoon, Small silver jig |
| Winter | 16 to 52 ft | midday | Deepest basin (52 ft) |
Start shallow in spring: european plaice sit in 8 to 35 ft that time of year. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 16 to 52 ft. The spot to know is DDM source-backed depth reference (7 ft), a feeding flat in about 7 ft of water that rates prime for european plaice in summer. Warm-month bites cluster around early morning and the evening. Throw a light spooned bottom rig or a beaded trace until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | DDM source-backed depth reference (7 ft) (7 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | DDM source-backed depth reference (7 ft) (7 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | DDM source-backed depth reference (26 ft) (26 ft) | Beaded bottom trace |
| Winter | 16 to 52 ft | midday | Deepest basin (52 ft) |
Start shallow in spring: whiting sit in 14 to 52 ft that time of year. They don't go far with the seasons — 15 to 52 ft covers summer, 11 to 52 ft covers winter. The spot to know is DDM source-backed depth reference (26 ft), a channel edge in about 26 ft of water that rates prime for whiting in spring. Warm-month bites cluster around early morning. Throw a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 14 to 52 ft | dawn & dusk | DDM source-backed depth reference (26 ft) (26 ft) | Small silver jig, Two-hook feather rig |
| Summer | 15 to 52 ft | dawn | Deepest basin (52 ft) | Small vertical jig |
| Fall | 9 to 52 ft | dusk | DDM source-backed depth reference (26 ft) (26 ft) | Small silver jig, Sparse feather rig |
| Winter | 11 to 52 ft | dusk | Deepest basin (52 ft) | Compact vertical jig |

Køge Bay - North is about 52 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.
Official coastal monitoring from DTU Aqua key-fisher monitoring, 2020–2022 informs the sea trout, atlantic herring, european flounder, garfish, european plaice, whiting, atlantic mackerel, common sole roster for Køge Bay - North. 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.
DDM source-backed depth reference (32 ft) is the top-rated area: a drop-off in about 32 ft of water that rates prime for sea trout in summer. The interactive chart above rates every spot for each 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.
