71,236-acre Anson Bay. Sector 09 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. Sector 09 trip-scale surveyed footprint within Anson Bay. A remote west Top End bay of the Daly River mouth, mangrove flats, channels and exposed outer water. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 141 ft. The depth chart comes from Geoscience Australia / AusSeabed 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.
The drawn water covers 71,234 acres wrapped in 53.4 miles of bank. Nearly circular (index 1.4), so the story is the bottom, not the bank. Roughly 3% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 13.7 mi, about 10.1 mi across. Its nearest charted neighbour, Anson Bay - Sector 05, is 11 mi to the north.
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.

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.

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 Anson Bay - Sector 09 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.
