"I got a phone call saying your trays are floating down the river so I rushed out here," she said.

As she got near the oyster farms in Greenwell Point at 9.30am she couldn't drive down, so in waste-deep water she waded her way to the depot.

"I got down here and was just devastated, everything was underwater, our trucks were underwater."

She used a washed-up burnt tree log to stop the water from flooding the shed before the worst of the king tide arrived.

"There was nothing else I could do except just pick everything up and move it out of the way."

"It was coming, there was no stopping it."

Only six months ago Sally Maclean took over running her dad's business, Jim Wild's Oysters.

They had been through large floods before but none with the amount of debris this one brought with it.

On Tuesday, some of the impacts of the flood started to become clearer.

The delivery truck was inoperable and the property was covered in sticks, mud and rubbish.

Thankfully, the tables and stools, made by the local men's shed, were heavy enough to not float away but had to be moved and cleaned.

A week since the flood tore through the river and oyster farm, Sally hasn't been able to fully assess the damage to her business.

"There's been a bit of infrastructure broken, mainly my poles, I haven't fully been able to assess the lease because every time I've gone out there's been water over it.

"There is a big tree sitting on one of my leases that I have to try to get off.

"And I've lost stock, it's probably just floated out the heads with the tides."

All the other oyster farmers in Greenwell Point are in the same boat.

On Friday, as Jim Wild's Oysters was selling some of the last stock collected before the flood, two farmers were carrying large tree branches in their punt back to the depot.

"On Tuesday morning when I came in I got two big box-trailer loads full of twigs, ash, debris all off my wharf.

"With our canal, the debris has only just started going now - as soon as it goes out, it goes straight back in."

A sludge of ash, bark and silt coats the water along the edges of much of Greenwell Point.

Jim Wild's Oysters has been impacted hard financially, because of fire and coronavirus and now the flood.

"We have a lot of international visitors that come too, so the coronavirus hasn't helped either on top of the bushfires - everyone's suffering."

Now Sally has to wait at least 21 days before they will start testing the water to see when they can harvest oysters again.

It's a long process.

Sally said if people wanted to help out, on Wednesday, February 12, they will be doing a clean-up with OceanWatch of the Shoalhaven and Crookhaven rivers.

She said if anyone in the community spots washed up oyster baskets, tumblers or infrastructure to let the farmers known.

"If they want to give one of us oyster farmers a ring we can come and pick it up because it costs a lot of money to replace those kinds of things," she said.

"And a little bit later on if everyone wants to come down and support the local farmers that would be fantastic."
