134,650-acre Fog Bay. West 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. West 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 102 ft. The depth chart comes from Geoscience Australia / AusSeabed 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.
Fog Bay - West maps at 134,648 acres behind 62.3 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 2% of the surface — that's where the groceries are. The basin spans about 20.5 mi end to end and 19.5 mi across at its widest. Fog Bay - Central sits 13 mi east — the closest neighbouring chart.
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.

Start shallow in spring: golden snapper sit in 8 to 35 ft that time of year. They don't go far with the seasons — 8 to 35 ft covers summer, 21 to 80 ft covers winter. Top water on the chart: Sharp break, a drop-off in the 43 ft range, good in fall. Fish it in early morning and the evening and you'll meet the bite.

When the water first warms, black jewfish slide up into 8 to 35 ft. There's no big seasonal slide here — summer means 8 to 35 ft, winter 21 to 90 ft. Start at Sharp break. It's a drop-off holding about 43 ft of water and rates good come fall. The feeding windows run early morning and the evening.

The spring pattern is a shallow one: king threadfin in 2 to 16 ft. The depth story barely changes: 2 to 16 ft through summer, 10 to 35 ft in winter. Plan around early morning and the evening in the warm months.

Early season queenfish use the shallows, holding in 3 to 25 ft. Even in summer they hold at 3 to 25 ft; winter keeps them in 15 to 55 ft. Put Sharp break first on the milk run — a drop-off near 43 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening.

The spring pattern is a shallow one: giant trevally in 4 to 30 ft. The depth story barely changes: 4 to 30 ft through summer, 18 to 80 ft in winter. The spot to know is Sharp break, a drop-off in about 43 ft of water that rates prime for giant trevally in fall. Plan around early morning and the evening in the warm months.

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 - West 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 - West is about 102 ft (31 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 golden snapper, black jewfish, king threadfin, queenfish, giant trevally, narrow-barred spanish mackerel, coral trout roster for Fog Bay - West. 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 43 ft of water that rates prime for queenfish in winter. Scroll up to the map for the complete spot list by species and season.
For golden snapper, 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 - West 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.
