The total storage in Sydney's dams is 95 per cent and climbing, but the state government is not talking about removing water restrictions.
Warragamba, the biggest dam, is 96 per cent full after dropping to 42,7 per cent in February this year.
Woronora Dam is at 78 per cent capacity, up 6.4 per cent in the last week.
Water Minister Melinda Pavey said Sydney's combined storage had risen by 9.8 per cent since last Friday as a result of the weekend rain event, 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, despite Warragamba being at almost 100 per cent capacity, we can't lose momentum by forgetting that every drop counts."
Mrs Pavey said while this is a welcome relief for Sydney residents, regional communities were still feeling the effects of drought.
"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.
