It would work but only be a short term solution. The damage has been done to
the biota from the acid sulphate/salinity.
The only long term solution is extensive plantings and wetland rehabilitation.
This includes all of the Murray-Darling Basin include the Darling River, the
Murrumbidgee River, the Lachlan River and all of their tributaries. It is not
just NSW. The Darling system starts in Qld with the Paroo and Warrego rivers.
Better controls of chemicals in the catchments. When the rains come all dam
wall have to be opened 100% and no pumping from any of the watercourses. The
system needs a full length full flood flush.
Before the days of dams and pumps the salinity would build up in the
waterholes from the natural salts then the river beds as they evaporated. When
the first rains came the initial flow would be very saline.

I'm not familiar with this area. Would it be impractical to build a weir so
that a small section could be flooded as a trial?
