3327-acre Polish Bornholm Basin Coastal Waters. Sector 04 Poland coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Polish POL200M/POL500M hydrographic DTM / traceable CDI assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Polish WFD named coastal or transitional assessment water in Polish Baltic Coast. This child is clipped to the exact source polygon and a trip-scale ownership window. Coverage classes and uncertainty limits are disclosed; this is a fishing-planning chart, not a navigation chart or catch forecast. The water tops out around 52 ft. The depth chart comes from EMODnet, with national hydrographic source-reference audit official hydrographic-chart depth models, so the contours are chart-derived rather than computer-modeled; no directly measured sounding coverage is claimed. What follows comes from the same scoring engine that paints the spots above.
On the chart, Polish Bornholm Basin Coastal Waters - Sector 04 draws 3,327 acres inside 12.5 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 29% of this chart. The basin spans about 5.3 mi end to end and 1.6 mi across at its widest. For a second option, Polish Bornholm Basin Coastal Waters - Sector 03 lies 7 mi southwest.
Occurrence evidence does not promise a catch or establish that retention is legal. Current seasons, closures, protected species, gear rules and local restrictions always control. 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. As the season builds they drop to 15 to 50 ft, wintering in 5 to 30 ft. Spring sea trout concentrate at Rock reef, a prime-rated rock pile around 6 ft. Warm-month bites cluster around early morning and the evening. 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 | Rock reef (6 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (35 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 | Rock reef (6 ft) | Slow coastal spoon, Suspending wobbler |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 16 to 52 ft. The spot to know is Deepest basin, a deep basin in about 51 ft of water that rates prime for atlantic herring in winter. Warm-month bites cluster around early morning and the evening. 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 | Rock reef (6 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Deepest basin (51 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Sharp break (35 ft) | Small feather rig, Compact silver spoon |
| Winter | 16 to 52 ft | midday | Deepest basin (51 ft) | Small silver jig, Sparse feather rig |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. Expect a summer slide to 6 to 35 ft, then a winter hold in 15 to 50 ft. Start at Sharp break. It's a drop-off holding about 35 ft of water and rates prime come fall. Prime time lands in 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 | Sharp break (23 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Sharp break (35 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Sharp break (35 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Deepest basin (51 ft) | Small bottom jig |
Spring puts garfish in skinny water — 1 to 15 ft is the zone. As the season builds they drop to 2 to 20 ft, wintering in 16 to 52 ft. Spring garfish concentrate at Shoreline point, a prime-rated point around 4 ft. Warm-month bites cluster around early morning and the evening. 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 | Shoreline point (4 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (4 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Sharp break (23 ft) | Weighted slim spoon, Small silver jig |
| Winter | 16 to 52 ft | midday | Deepest basin (51 ft) |
Spring atlantic salmon on Polish Bornholm Basin Coastal Waters - Sector 04 hold shallow, usually 5 to 30 ft. They move out to 15 to 52 ft in summer and finish the year down in 10 to 45 ft. Put Deepest basin first on the milk run — a deep basin near 51 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a trolling spoon or a flasher + fly.

Polish maritime administration ports and harbours review was reviewed, but no stable government record establishes a public fishing entrance, parking or launch for this exact mapped child. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, port and harbour rules, protected areas, local signs, parking, safety, permits and fishing permission before entry.
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Poland waters are set by the Polish Ministry of Agriculture and Rural Development (current recreational marine-fishing rules) — and special regulations can apply to Polish Bornholm Basin Coastal Waters - Sector 04 specifically, so confirm the current rules before you fish. Check Poland's live national and EU Baltic recreational-fishing rules before every trip. Fees, permitted methods, protected sizes and periods, species prohibitions, harbour spinning closures, marine protected areas and local port or shoreline directions can change. Directed recreational retention of cod, eel and some salmon is restricted or prohibited under the cited framework; never infer an open fishery from a regional occurrence roster. An official DTM contour, fishing spot or nearby port reference is planning context only and never grants fishing, retention, access, parking, launching, port-entry or safe-navigation permission.

Polish Bornholm Basin Coastal Waters - Sector 04 is about 52 ft (16 m) deep at its deepest point. The depth chart comes from EMODnet, with national hydrographic source-reference audit official hydrographic-chart depth models, so the contours are chart-derived rather than computer-modeled; no directly measured sounding coverage is claimed.
Official coastal monitoring from Poland national fisheries and coastal monitoring agencies informs the sea trout, atlantic herring, european flounder, garfish, atlantic salmon, european smelt, european perch, zander roster for Polish Bornholm Basin Coastal Waters - Sector 04. 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.
Rock reef is the top-rated area: a rock pile in about 6 ft of water that rates prime for sea trout in spring. 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.
