Mardi water storage

A new urban water supply system in New South Wales has been added to the Bureau's Water Storage website. The three major dams in the system supply the large population centre of the Central Coast, north of Sydney.

The storages – Mangrove Creek, Mardi and Mooney Mooney – are owned and operated jointly by the Gosford City and Wyong shire councils.

Amendments to Water Regulations 2008

On 10 May 2012, the Governor-General amended the water information provisions of the Water Regulations 2008.

Changes have been made to each of the ten water information categories to enhance the quality and usefulness of water information received by the Bureau.

Most of the changes will take effect on 5 July 2012, except for the amendment relating to a new Person Category (Category J – Owners or Operators of Hydrologically Significant Sites) which will not come into effect before 2013.

The amendments were drafted following consultation undertaken in 2011. Many of the comments received through this consultation were incorporated into the amendments.

The 2011–12 La Niña ended in March, following the second successive summer in which La Niña contributed to significant rain and flooding across many parts of Australia.

The period from April 2010 to March 2012 was Australia’s wettest two-year period ever recorded. Despite its demise, ocean temperatures around parts of Australia remain very warm, and hence above-average rainfall is still forecast for some regions.

So with La Nina finished, what can we expect next?
