Blowering Dam to the south east of Wagga and Burrinjuck Dam to the north east are both expected to receive increased water after recent rainfall, and are currently at 93 per cent capacity and 80 per cent capacity respectively.
Water NSW said releases of water from the dams for more airspace will likely increase in coming days to mitigate risk of flooding.

"We will use [Bureau of Meteorology data] to help us decide whether to make flood mitigation pre-releases in the event of a significant rain forecast," Mr Langdon said in a statement.
"As dam managers we are mindful that we cannot make releases... without a high degree of certainty that the anticipated inflows will replace those releases, and therefore not impact adversely on long term water security."
Scheduled maintenance of Blowering Dam in July has been cancelled in the wake of the water uptick, as it would have called for releases to be closed off entirely for the duration.
The shutting off of water releases would have seen river flow as far as Goobagandra reduced to almost zero for the duration of the works.
"For these particular works on Blowering Dam we need to cease releases, and given this [rainfall] weather event and its proximity to works we've decided to postpone them," a Water NSW spokesperson said.
"With a high storage you want to maintain operability, if you turn off the releases you can't operate it."
However, Bureau of Meteorology meteorologist Hugh McDowell said no unprecedented rainfall levels are expected in the Riverina, with the main heavy rain hitting south of the border.
"The south west region has seen 20-40 ml of rainfall in the past 24 hours," he explained. "It's a reasonable amount of rainfall but a lot of the heavier rain has been over in VIC."
He said there seemed little likelihood the area would experience much extra water based off the predicted rainfall.
