Between 50mm and 70mm of rain was dumped on Canberra over the weekend even more in some catchment areas producing the best inflows to Canberra's reservoirs in five years.

The big wet translated to about 10 gigalitres flowing into three of the ACT's four reservoirs the fourth being already full. The combined ACT water storage yesterday was sitting at 72.3 per cent, up from 66.1 per cent on Friday morning. The previous significant inflows were in 2005 when reservoir levels reached about 68 per cent. Reservoirs have not been at their present levels since July 2002.

Actew managing director Mark Sullivan said that even without forecast further rain, storages would be more than 75 per cent full and the capital's water restrictions could be eased even further after they were relaxed from stage3 to stage2 last Wednesday.

''The possibility of dam levels going to 80 per cent is very real,'' MrSullivan said yesterday.

''If it went to that level we would have to review water restrictions again. We had thought the recent review would be the end.''

Any further reduction would reintroduce permanent water conservation measures which would allow sprinklers to be used from 7am to 10am and from 7pm to 10pm.

''I am sure no one is thinking of using their sprinklers at the moment,'' Mr Sullivan said.

Although the weekend soaking spelled mostly good news for the capital, winds up to 85km/h generated plenty of headaches, with the ACT State Emergency Service receiving 372 calls for help during the weekend.
