DAYLESFORD and Hepburn residents are being urged not to become complacent with their use of water heading into summer.

Water storages supplying Daylesford, Hepburn and Hepburn Springs are at 100 per cent full, or 828ML.

Daylesford's full levels are in direct contrast to Ballarat's critically low levels sitting at just under 12 per cent of capacity.

However despite the healthy water supply Central Highlands Water spokesman Phil Anstis said the situation could change quickly.

"It's a relatively small system and can respond very quickly to rainfall and inflows which it has done over the year," Mr Anstis said.

"But it can also deplete reasonably quickly as well so given the uncertainty around the dry period we are asking to be conservative about their water usage."

Mr Anstis said it was unlikely stage three water restrictions would be lifted when the CHW board meets on Tuesday, September 25.

Under stage three water restrictions new outdoor pools and spas must not be filled. Existing pools and spas greater than 2000 litres in capacity can only be filled after preparation of a water conservation plan and written permission

from CHW.

Meanwhile Hepburn Shire Council is planning to open all three of its pools for this summer.

Last week it was reported CHW had advised the Ballarat City Council it would be unlikely all pools in the city would be allowed to open because of critical water shortages.

CHW allowed the Hepburn Shire Council council to fill the Daylesford pool last summer under strict conditions.

The Trentham and Clunes pools aren't affected by CHW restrictions.
