Sydney Water head of water supply and production, Ben Blayney, said when dam levels start to fall, they can drop quickly.
"We cannot wait until the dams are empty to take action," he said.
"What we can see as part of our daily monitoring processes is a series of red flags. These are the same trends we experienced going into the last drought.

Brownsville is the only Illawarra suburb to make Sydney Water's top 10 list of lowest water consumers for the first quarter of 2023. It ranked eighth with 35.25 kilolitres used per household.
Gerroa ranked fourth at 30.05kL, and the lowest consuming suburb was Berowra Waters, on Sydney's northern outskirts, at 23.84kL.
The highest water use was in Duffy's Forest on Sydney's northern beaches at 178.91kL per household. It was followed by some of Sydney's richest suburbs including Point Piper (175.13kL), Bellevue Hill (124.66kL), Centennial Park (116.70kL) and Darling Point (115.56kL).
Sydney's water desalination plant is used to supplement dam water for the Illawarra.
Water efficiency tips
Simple steps can be taken to help reduce the amount of water you use.
- Fixing leaks are the quickest way to save water
- Use a watering can or hose with a trigger nozzle to target areas that need water and avoid overwatering
- Water before 10am or after 4pm, when the sun's low. You'll reduce water loss through evaporation
- Using a pool blanket can reduce evaporation by up to 90 per cent
- Take shorter showers. Every minute under a shower with a standard showerhead uses around 9 litres of water
- Turn off the tap while you brush your teeth
- Only wash when you have a full load
- Fill a jug and keep water in the fridge so you don't have to wait for tap water to run cold
