Volume of Dam Wall[edit]

I'm new to this editing stuff, so I hope I'm doing this correctly. The dam volume of 2124 cubic metres appears to be the wrong magnitude - it is much too small for a wall that is 4800 metres long. It indicates that there is only 0.5 cubic metres of volume per metre of wall length. — Preceding unsigned comment added by Frogfund (talk • contribs) 15:46, 9 January 2019 (UTC+11)

It does seem low, even though the dam wall is not a consistent height. The wall itself is packed earth with a bentonite clay core brought up to a consistent height although the area surrounding the dam varies in height. According to this there are several incorrect figures in the article. --AussieLegend (✉) 06:31, 9 January 2019 (UTC)[reply]
