The total storage in Sydney's dams is more than 98 per cent and climbing, but the state government is not talking about removing water restrictions.
Warragamba, the biggest dam, reached 100 per cent capacity on Monday and is spilling after dropping to 42.7 per cent in February this year.
Woronora Dam was at 78.5 per cent capacity, up seven per cent in 10 days.
Water Minister Melinda Pavey said Sydney's combined storage had risen by more than 10 per cent in a week as a result of the rain event between August 7-10, which generated the best inflows in six months.
"However, much of regional NSW remains in drought," she said in a statement.
"Water is a precious resource and...we can't lose momentum by forgetting that every drop counts.
"While Greater Sydney's water supply is healthy, our regional catchments continue to slowly recover from one of the worst droughts on record," she said.
Under level 1 restrictions, which remain in place, Sydney residents are only permitted to water their gardens with a hand-held hose fitted with a trigger nozzle, a watering can or a bucket before 10am and after 4pm.
The government is scheduled to review water restrictions in December.
The desalination plant continues to operate with minimum production, which can be quickly increased if there is any problem with dam water quality being affected by bushfire ash.
