Estuaries with large catchments, like the Tuross, Moruya, Clyde and Shoalhaven systems, have been hardest hit and will take a while to clear.

It's hard to gauge how long the fishing will take to bounce back.

Over the next week or so, anglers' focus should be on the lower reaches of the estuaries on the incoming tide.

Bream, trevally, tailor, salmon and blackfish are likely to be scavenging for food in these areas. There's also the chance of crossing paths with larger predators like mulloway and sharks.

Forget the middle and upper reaches until at least Easter - these sections will be too fresh and discoloured for most species.

Wagonga Inlet at Narooma, which has a very small catchment, clears up rapidly and will fish well as early as this weekend.

It's already been producing flathead, bream and small mulloway.

Wild seas, which accompanied the deluge, are starting to abate. There should be some decent fishing for snapper, bream and drummer off the stones as calmer conditions return.

In saying that, there's no need to rush back to the rocks. Play it safe and wait until the seas die down - the fish will still be there.

Locally, the rain has put fishing on hold but there should be some good action once the skies clear.

Googong Dam is 100 per cent full and overflowing. It was fishing well before the drenching for redfin and golden perch, and it should fire up again soon.

The urban lakes will be extremely discoloured in the immediate future, but bait fishing should still yield plenty of redfin and carp, as well as the odd yellowbelly.
