Best tide state to fish The Causeway (Swan River)

This is lower-river saltwater at the eastern edge of the estuary, with tidal current funnelling around the island and under the two spans on every change. Tide changes are the productive windows; slack water in the middle of the tide is slow. The afternoon seabreeze funnels down the river corridor in summer, but the fish hold on structure rather than roaming, so the spot stays workable in most winds. Water clarity is generally reasonable but colours up and tannin-stains for days after heavy winter rain pushes fresh down the Swan.

What anglers target here

Anglers fishing The Causeway (Swan River) typically time sessions around the tide for black bream, flathead, tailor, cobbler, and mulloway (jewfish).
