Satellite images of Hawkesbury River flooding show true extent of NSW devastation

Satellites orbiting the earth's exosphere have been able to capture the true extent of the past week's flood devastation in NSW.

The imagery shows fields and properties along the Hawkesbury River completely underwater.

The entire NSW coast has been drowned by at least 200 millimetres, and in some places, more than 400mm of rain.

To put that in context, Sydney averages 132mm of rain for the whole month of March.

As the pictures show, much of Windsor and its surrounding areas have been swallowed by the swollen river and houses are now islands in an ocean of flood water.

Although river levels are slowly falling from their peaks, flooding continues in Windsor and nearby North Richmond today.

On Wednesday, the Hawkesbury River at Windsor peaked at 12.9 metres above sea level.

Many residents in both towns remain cut off and groceries, medical supplies and veterinary supplies are being moved by boat across the river.

As the devastation becomes more clear, residents in these communities know they have a long road to recovery ahead.

Many have only just been reunited with their loved ones.

"Families are isolated, they are hungry there's no food, the generators are running out so there's no water to pump to the toilets...no water to drink,"  SES Hawkesbury unit commander David King said.

Stacey Gosper was separated from her three children for almost seven days.

"The isolation has been horrendous," she said.

"Nothing could get this lot off my mind, they are still very young and they need their mum."

Ms Gosper sent her children to her mother's place in Bligh Park, just south of Windsor, thinking they would be safer there than in North Richmond.

But her mother's home became flooded too.

"I was thinking the flood would be the same as last year and only last three days.

"I'm so glad to have my kids back."

Some buildings are no longer visible at all.(

Farmers say they may need to start from scratch after losing almost their entire livelihood to the waters.

"It just breaks your heart," said turf farmer Daniel Saliba , who now has 60 hectares of land to mop up.
