91,210-acre Fog Bay. Northeast Australian saltwater fishing map showing only directly measured AusBathyTopo 2026 cells, source-qualified fishing spots, official regional fish evidence, seasonal forage context, access guidance and current-rule links. Northeast trip-scale surveyed footprint within Fog Bay. An open tropical bay linking Bynoe and Daly approaches, with reef, shoal, beach and estuary-mouth structure. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 108 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Fog Bay - Northeast runs 91,200 acres with 99.6 miles of edge. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. 34% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 20 mi long by 17.1 mi wide at the broadest reach. The nearest mapped water is Bynoe Harbour - West, 8 mi to the west.
Regional occurrence does not mean equal abundance, child-specific catch rate, retention permission or a promised catch. Live state, territory, Commonwealth, protected-area and local rules 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.

Early season barramundi use the shallows, holding in 2 to 18 ft. Even in summer they hold at 2 to 18 ft; winter keeps them in 11 to 35 ft. The chart's best answer is Sharp break — drop-off, 32 ft, good for winter. Best bite is early morning and the evening.

Spring golden snapper on Fog Bay - Northeast hold shallow, usually 8 to 35 ft. Depth-wise the year is flat: 8 to 35 ft in summer, 21 to 80 ft once it turns cold. Put Sharp break first on the milk run — a drop-off near 54 ft that grades good for fall. The feeding windows run early morning and the evening.

No facility from the cited Northern Territory boat ramps source was spatially attached within 3 km of this directly measured map footprint during the 2026-09-08 audit. This is an evidence gap, not a claim that public access is absent. Check the official portal, live site signs, tides, ramp condition, vessel suitability, fees, parking, working-port restrictions and landowner permissions before travel: https://nt.gov.au/marine/for-all-harbour-and-boat-users/boat-ramps
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Northern Territory waters are set by the Northern Territory Government (current recreational-fishing rules) — and special regulations can apply to Fog Bay - Northeast specifically, so confirm the current rules before you fish. Check the Northern Territory's live possession and size limits and rules for specific areas before every trip. Seasonal barramundi controls, protected species, marine-park and Aboriginal land or sea-country permissions, method limits, vessel rules and local closures can apply. Remote-water access often needs separate landowner or permit approval. A mapped survey footprint, fishing spot or access lead never grants fishing, retention, entry, parking, camping or launching permission.

Fog Bay - Northeast is about 108 ft (33 m) deep at its deepest point. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Northern Territory Department of Agriculture and Fisheries regional evidence informs the barramundi, golden snapper, black jewfish, king threadfin, queenfish, giant trevally, mangrove jack, narrow-barred spanish mackerel, coral trout roster for Fog Bay - Northeast. 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.
Shallow measured flat is the top-rated area: a feeding flat in about 3 ft of water that rates prime for king threadfin in spring. Every other rated spot, per species and season, is on the map above.
For barramundi, 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 Fog Bay - Northeast is regulated by the Northern Territory Government (current recreational-fishing rules). Check the official Northern Territory regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
