West Wimmera Shire Council chief executive Mark Crouch.GWMWATER believes it will cost between $4.1 and $8.2 million to fill the drying Lake Wallace.
West Wimmera Shire Council investigated the cost to fill the Edenhope lake after residents raised concerns.
Edenhope and District Historical Society requested council find out what could be done about declining water levels.
Society secretary Geoff Langsworth said the low levels were affecting the town’s economy.
Council will discuss GWMWater’s findings at its December meeting at Edenhope on Thursday.
Chief executive Mark Crouch said in a report to council that GWMWater indicated any proposal that took in a raw water supply as well as recreational water would have an estimated cost ranging from $4.1 million to $8.2 million.
‘‘In relation to recreational water operating fill costs, based on water availability, to fill Lake Wallace at 5682 megalitres would have a potential fill cost of $113,640 if the full volume was required,’’ he said.
‘‘It would appear the main issues will centre on capital costs to establish a suitable supply infrastructure and the availability, willingness and capacity of GWMWater.’’
West Wimmera staff recommended council took no action to fill the lake.
Mr Crouch said GWMWater indicated there would be no short-term alterations to the water supply to Edenhope.
GWMWater managing director Mark Williams said in a letter to council that the authority was about to commission a new bore at Harrow to give the town a secure water supply.
‘‘GWMWater will be reviewing its Water Supply Demand Strategy as a feed into the next regulatory pricing proposal for 2018-2023,’’ he said.
‘‘As part of this review, we will assess the medium and long-term sustainability of the current bore supply to Edenhope and Harrow.’’
Mr Williams said GWMWater did not have a service obligation for the provision of recreational water supply to recreational lakes.
