85,503-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 85,393 acres with 56.6 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 17.7 mi of water from one end to the other, 13.2 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. Sharp break is the standout, a drop-off at roughly 45 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 measured point (15 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (45 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | DDM measured point (15 ft) | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | DDM measured point (15 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | DDM measured current seam (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 measured current seam (22 ft) | Small feather rig, Compact silver spoon |
| Winter | 16 to 52 ft chart-limited; documented 20 to 60 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 Feeding flat: a feeding flat around 6 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 | Feeding flat (6 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (6 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (6 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 measured point is the standout, a point at roughly 15 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | DDM measured point (15 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | DDM measured point (15 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | DDM measured current seam (22 ft) | Weighted slim spoon, Small silver jig |
| Winter | 16 to 52 ft chart-limited; documented 20 to 60 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 Feeding flat, a feeding flat in about 6 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 | Feeding flat (6 ft) | Beaded flowing trace |

| Fall | 10 to 50 ft | dusk | DDM measured channel edge (26 ft) | Beaded bottom trace |
| Winter | 16 to 52 ft chart-limited; documented 25 to 80 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 measured channel edge, 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.

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 Køge Bay - 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.

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, thick-lipped grey mullet, brill, saithe (coalfish) 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.
Sharp break is the top-rated area: a drop-off in about 45 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.
Fishing on Køge Bay - North is regulated by the Danish Agency for Green Transition and Aquatic Environment (current recreational fishing rules). Check the official Denmark regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
