Overview
Completed in 2001, the dam is 8 metres (26 ft) high and 129 metres (423 ft) long. The resultant 2,600-megalitre (2,100 acre⋅ft) reservoir draws from a catchment area of 760 square kilometres (290 sq mi).[1]
The Teviot Creek is a tributary of the Isaac River, upstream of the Burton Gorge Dam.
Burton Coal Pty Ltd, who built the dam, have a licence to draw 1,500 megalitres (1,200 acre⋅ft) per year from the dam.[citation needed] The monthly supply reliability based on a relatively short period of record is thought to be 100%. This does not account for the current critical period and the supply should not necessarily be relied on in future. The Teviot Creek Dam is owned and operated by RAG Australia Coal subsidiaries.[2]
