But, a report going to Riverina Water's board meeting next week says the expected summer conditions could trigger tighter restrictions if demand becomes high enough.

Permanent Riverina Water restrictions ban the use of fixed sprinklers between 10am and 5pm every day.

Tighter restrictions can either be enforced by an instruction from Water NSW or by Riverina Water when demand exceeds 90 megalitres a day.

Riverina Water general manager Andrew Crakanthorp said both Blowering and Burrunjuck dams "have still got a lot of water".

But, with current water production sitting at between 70 and 75 megalitres a day, it is possible demand will exceed 90 megalitres a day in hot, dry weather.

"But no restrictions are imminent," Mr Crakanthorp said.

Many parts of Sydney are already on stage two restrictions and facing even tighter controls within months, while towns in northern NSW are planning for a "day zero", when they run out of water, as rivers including the Barwon and Namoi are dry.

The board meeting will also discuss preliminary results from a customer survey, which showed "the majority of customers surveyed know the steps to conserve water and are also concerned about the future and current availability of water".

Greens campaigner Michael Bayles has expressed concerns about the city's water usage, saying "we are probably too liberal with our water use when there are so many towns facing shortages".

"It does feel wasteful to be watering our lawns," he said.

"For us in Wagga to be flouting our water when others are running out is not a good look."

Meanwhile, the Wagga Country Club has put a $2 per round levy on all players to help cover the cost of watering the course.

In a letter to members, secretary-manager John Turner and president Tom Curtis wrote that the club has spent $62,000 on course water since March.

"With the state in drought conditions, the impact has also affected the club and our access to water from Lake Albert," they wrote.

"After extreme conditions in the summer of 2018-19 and a dry winter, our access to Lake Albert to water the course ceased on March 12, 2019.

"In February we asked Riverina Water for consideration for a reduced rate for water, but this was denied.

"Since this time, we have been accessing water from the town's supply which has been mainly trying to keep our greens in good condition.

"An audit was done on our irrigation system to maximise our water usage to include the tees and landing zones when possible.

"The club continues to meet with council regularly to stay informed of proceedings to try and find a permanent solution to Lake Albert."
