Birds flock back to the Gwydir wetlands

Watch this Prime7 news clip showing how natural flooding and the strategic delivery of environmental water coordinated by the Office of Environment and Heritage (OEH) have helped water birds thrive after years of drought:

Extra water helps fish in the Edward-Wakool river system

Dissolved oxygen levels are now being boosted in this popular fishing river system thanks to extra environmental water deliveries being coordinated by OEH.

Recent rainfall and flooding throughout the catchment had caused extra organic material to be deposited into the river, resulting in a ‘blackwater’ effect and lowering dissolved oxygen levels to below 2 milligrams per litre. This may have been causing native fish such as the Murray cod and yellow belly to experience severe stress and possible death.

It is expected that by 30 June 2012, up to 60 gigalitres of environmental water will have been released into the Edward-Wakool river system, since environmental releases commenced in early April.

There are promising signs that the poor quality blackwater is being diluted and better quality habitat created for native fish and other aquatic fauna.The Edward River at Moulamein recently registered healthier oxygen levels of around 4 milligrams per litre and there have been very few reports of fish kills to NSW Fisheries and the Murray- Darling Basin Authority.

This initiative has been delivered in partnership with the Commonwealth, State Water Corporation, Murray CMA, Forests NSW, NPWS, NSW Office of Water, Fisheries NSW, the river operators and the local community. All the environmental water for this event was sourced from the Commonwealth Environmental Water Holder.

Water release revives Lowbidgee wetlands (September 2010)

April 2010

The Lowbidgee Wetlands near Balranald come to life after 8200 megalitres of NSW and Commonwealth environmental water was released via the North Redbank channel in March and April.

Birds flocked and vegetation flourished as the water spread across the floodplain on seven private properties: 'Murrundi', 'Springbank', 'Glen Avon', 'Auley', 'Moola', 'Riverleigh' and 'Baupie'. View video transcript (LowbidgeeWetlandsVideoTranscript.doc; 34 KB)
