Junee's 50-metre pool has been reduced to 25 metres and will be a welcoming 26 degrees Celsius.

But while the temperature is up, fewer visitors mean the centre will move into its "low patronage" mode.

It means from Monday to Friday, the pool will be open from 6am to 8pm and on Saturday from 9am to 1pm and 11am to 3pm.

Junee Shire Council's general manager James Davis said low patronage mode was about trying to minimise the operational costs while fewer people went swimming.

"If there's less than 25 people in the pool, supervision is done by staff on a regular basis, but there isn't a lifeguard on the pool deck," he said.

Mr Davis said some visitors had told council they felt they were taking up staff time when they were the only person in the pool while a lifeguard was on duty.

"We implemented it (low patronage mode) to good effect last year," he said.

While operating hours have been reduced for winter, council is also seeking a grant to fund improvements and efficiencies.

"We've been informed by the Independent Pricing and Regulatory Tribunal (IPART) gas prices could rise by as much as three times their current prices over the next five years," Mr Davis said.

"We want to be able to maintain or increase access to the centre for the public but we have to find ways to reduce operational costs - the majority of which is energy and gas use."

Part of the grant application is a feasibility study on opening the gym 24 hours a day for members.

"We've listened to members who have been calling for extended access to the gym," Mr Davis said.

"There's up to 400 people in town on shift work.

"We see an opportunity to extend our memberships by offering more flexible access."
