92,275-acre Waterford Harbour. Outer East saltwater fishing map with official INFOMAR survey bathymetry, measured-cell fishing spots, official fish evidence, seasonal forage guidance, access context and current-rule links. The outer east trip-scale survey reach of Waterford Harbour, retaining only official survey-backed seabed cells that pass the Ireland release gates. The water tops out around 228 ft. The depth chart comes from INFOMAR (Geological Survey Ireland and Marine Institute) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 92,302 acres wrapped in 48.2 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. 0% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 14.8 mi with a 13-mi widest point. If the bite dies, Waterford Harbour - Inner is 11 mi to the north.
Marine Institute spawning, nursery, observation and range layers support the principal surveyed pelagic and groundfish. IFI's national and regional sea-angling publications support additional habitat-compatible recreational targets. This is occurrence and search guidance, not equal abundance, a section-level population estimate or a promised catch. 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 european seabass on Waterford Harbour - Outer East hold shallow, usually 3 to 25 ft. They move out to 2 to 30 ft in summer and finish the year down in 10 to 55 ft. The feeding windows run early morning and the evening. The summer box starts with a surface lure or a paddle-tail soft plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | open water | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | open water | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | open water | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. Warm water sends them out to 15 to 80 ft; cold water stacks them in 30 to 120 ft. INFOMAR measured channel edge is the standout, a channel edge at roughly 125 ft, rated good for winter atlantic mackerel. Plan around early morning and the evening in the warm months. A feather rig or a small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | open water | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | open water | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | INFOMAR measured channel edge (125 ft) | Small deep jig |
Spring atlantic herring on Waterford Harbour - Outer East hold shallow, usually 5 to 25 ft. They move out to 15 to 50 ft in summer and finish the year down in 20 to 60 ft. The feeding windows run early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | open water | Small herring feather rig, Micro jig rig |

Come spring, look for whiting tight to the bank in 15 to 55 ft. They move out to 20 to 70 ft in summer and finish the year down in 15 to 70 ft. Best bite is early morning. A small vertical jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |

Spring puts european flounder in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 6 to 35 ft; cold water stacks them in 15 to 50 ft. Plan around early morning and the evening in the warm months. A bottom jig with spinner blade covers the summer program.

The complete Marine Institute Fishing Ports layer returned no port point inside this operational section. DepthScout does not substitute a nearby road, beach or community slipway as verified public fishing access; confirm legal access, parking, tides and local restrictions before visiting.
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Ireland waters are set by the Inland Fisheries Ireland (current sea-angling regulations) — and special regulations can apply to Waterford Harbour - Outer East specifically, so confirm the current rules before you fish. Check the current national and water-specific rules before every trip, including bass measures, the 2026 recreational pollack controls, salmon and sea-trout licences and river-specific status, protected areas, harbour directions, private land and local signs. A mapped fishing port or measured seabed feature is not permission to fish, park, launch or enter a working harbour.

Waterford Harbour - Outer East is about 228 ft (69 m) deep at its deepest point. The depth chart comes from INFOMAR (Geological Survey Ireland and Marine Institute) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Marine Institute and Inland Fisheries Ireland informs the european seabass, atlantic mackerel, atlantic herring, whiting, european flounder, european plaice, common sole, thornback ray, brill, thick-lipped grey mullet, garfish, atlantic cod roster for Waterford Harbour - Outer East. 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.
INFOMAR measured channel edge is the top-rated area: a channel edge in about 125 ft of water that rates good for atlantic mackerel in winter. Open the map above to see every rated spot for each species and season.
