Plummeting temperatures and heavy rain trigger a spawning response in mature browns, and they gather in huge numbers in April, May and June to head up the rivers and streams to reproduce.

Literally tens of thousands of fish will do this over coming weeks and months in lakes Eucumbene, Jindabyne and Tantangara - and it begins now.

There have already been signs of massive trophy browns moving towards the river mouths.

Most are still sitting deep in the lake, feeding on yabbies and waiting for more signs from Mother Nature - namely, a repeat of last week's icy blast.

So dust off your glo-bugs and hard-bodied minnows - with so much water around, the scene is set for one of the best spawning runs in years. Stay tuned.

The South Coast can't take a trick at the moment. After being pummelled by torrential rain and flooding for weeks, the coast was last weekend slammed by some of the heaviest surf in recent memory.

Six-metre swells, powerful enough rip up the cement footpath on the Moruya Breakwall, made it impossible to fish anywhere near the open ocean.

On a positive note, the fishing from the rocks and beaches should be excellent as the seas abate.

Before the wild weather, there were reports of good catches of salmon, tailor, bream, snapper, drummer, bonito and frigate mackerel from the stones. Expect the action to be even livelier after this latest storm.

The calm estuaries have been the saviour of late, and they're all fishing extremely well as we head towards the Easter and Anzac Day long weekends.

April is crossover species time, so expect mixed bags of flathead, bream, trevally, tailor, whiting, blackfish and salmon.
