Dam levels - what's the Council up to?

The Toowoomba City Council's Water Futures website showed the following figures on 30 March:

Overall (combined dams)
Percentage of Capacity = 24.3%
Volume = 30.8 Gigalitres
Days Supply = 1140.0 Days Supply

But on 1 April, the same page showed:

Overall (combined dams)
Percentage of Capacity = 24.3%
Volume = 30.8 Gigalitres

There was no longer a "Days Supply" figure.

Did the figure of 1140 days (a little over 3 years supply) not suit their "water will run out" argument?

Just a thought ...
