With its storage levels hovering above 50 per cent, Blowering Dam is holding up better in the dry conditions than many others in NSW.
On Monday, Blowering's level was at 52.6 per cent, while Burrinjuck Dam was at 32.5 per cent.
The figures for these southern NSW dams contrast sharply with those in the state's drought-ravaged north.
Keepit Dam, near Tamworth, for example, was at just 1.0 per cent of storage capacity, while Copeton Dam near Inverell was at 8.8 per cent.
A spokesman for Water NSW said that while higher storage levels would be welcome going into what is predicted to be a drier and warmer-than-average spring, Blowering and Burrinjuck were "quite good" compared to the rest of the state.
In 2003, during the millennium drought, storage levels at Blowering Dam dropped to less than 1 per cent, while Burrunjuck's also dipped into single figures.
Blowering has an available capacity of 1,628,000 megalitres, which is roughly three times the size of Sydney Harbour.
This week, there was even a little good news for irrigators, with general security allocations for water increasing from zero to three per cent.
The Water NSW spokesman said both Blowering and Burrinjuck remain open as normal to recreational users.
In contrast, in the state's north, Tamworth residents could face an upgrade from current level four water restrictions to level five as a warmer and drier-than-average springs kicks in.
Riverina Water has in place what it calls a water conservation measure, which means fixed sprinklers cannot be used between the hours of 10am and 5pm and applies to all customers, including residential, commercial and industrial customers.
Greg Verdon, the chairman of Riverina Water, said this region's water was sourced from an underground aquifer, rather than relying on dams like parts of northern NSW.
Councillor Verdon said despite the predictions for a dry spring, there were currently no plans to introduce water restrictions beyond the current conservations measures.
"Our water supply is very good," he said.
"We will have to monitor it as the dry spell continues. We always encourage people to use water wisely."
Cr Verdon said he had been this week been talking with councillors from across NSW and heard the extent of the concerns about water in the state's north.
"We are very lucky that the aquifer has been a very reliable source of water," he said.
