1.1 Storages

Supporting information

The volume recognised in the water accounting statements (500 ML) represents the volume of water held in the Copperfield Dam at 30 June 2012. This is the only surface water storage within the Daly region and is used for the town of Pine Creek's water supply.

Quantification approach

Data source

Operational storage database.

Provided by

Power and Water Corporation.


Storage level data are not collected at Copperfield Dam and so it was assumed the storage volume at 30 June 2012 was the storage capacity of 500 ML.

Assumptions, limitations, caveats and approximations

It is assumed the storage is at capacity at 30 June 2012. This is likely to be an overestimate of the actual volume of the storage at this date.

Uncertainty information

The uncertainty estimate was not quantified.
