The Murray-Darling Basin is an incredibly complex ecological system.
A recent report argues more water is needed to resurrect the Murray-Darling Basin. But simply increasing river flow alone could actually harm the Basin.
Turtle hatchlings could be released into the Murray River to manage the sudden influx of dead carp.
Millions of dead carp will fill the Murray-Darling Basin after the government releases a targeted virus. Scavengers like turtles and crayfish might help – as long as we protect them.
Water markets are essential for many farmers to keep their crops alive.
The market for water entitlements is worth tens of billions, encouraging investors to raise funds and get involved. But the data shows they aren't having a big impact on prices.
The Murray-Darling is a complex freshwater ecosystem.

Tempers have flared once again over the long-term plan to return water to the Murray-Darling River and improve its health.
Nick Xenophon had previously said he would not vote on the ABCC legislation until the water issue was settled.
Malcolm Turnbull has promised key crossbencher Nick Xenophon closer monitoring of the Murray-Darling Basin Plan.
Malcolm Turnbull goes into this final parliamentary week of the year in need of compromises on both the ABCC legislation and the tax rate for backpackers.
Malcolm Turnbull has assumed responsibility personally for negotiating with key crossbencher Nick Xenophon over water.
Earlier this week, footage aired of George Brandis speculating that Queensland's Liberal National Party might demerge. But Barnaby Joyce says this won't happen.
Spangled perch are one of Australia’s strongly migratory native fish. After storms in January 2015 these fish were actively travelling up a flooded road in outback Northern Territory.
Freshwater fish are declining everywhere, in part thanks to dam-building. But we can have both.
Fixing water pollution on the Great Barrier Reef will take a huge effort.

Efforts to combat water pollution on the Great Barrier Reef aren't working, according to a new government report.
Blue-green algae in the Murray River upstream of Mildura in April.
Toxic algal blooms were unheard of in Australia's major waterways before 1991. Now the Murray River has been struck by four major events in less than a decade, with more likely in the future.
Barkindji protest outside Parliament in Canberra.
For the Barkindji people, the Darling River has been a symbol of Aboriginal survival since colonial times. Now, the once busy NSW town of Wilcannia is in danger of losing its water.
Northern rivers could increase Australia’s irrigated land by 50%. But we need to think about the environmental impacts.
It's full steam ahead for bringing vast increases in farming to northern Australia. In fact, probably too fast to adequately consider the environmental impacts.

As El Nino looms, the Murray-Darling is facing another drought. But after almost a decade of investment in water trading and other policies, its prospects are better this time around.
University of Canberra Professorial Fellow Michelle Grattan and and Deputy Vice-Chancellor (Research) Frances Shannon discuss the week in politics.
The Onkaparinga River, part of the catchment that supplies around half of Adelaide’s drinking water.
Imagine a future where the yearly flow into one of the largest water reservoirs of a major Australian city could halve within 70 years. This is a scenario that Adelaide could face if the world continues…
Australia’s north is home to many pristine rivers, but most national parks are focused on land-based conservation.

Freshwater ecosystems such as rivers, lakes and wetlands are precious. They contain several-times more vertebrate species per unit area than land and ocean environments, and they are more degraded. Protected…
Spending on water-saving infrastructure could expose Murray-Darling farmers to debt and drought.
The federal government’s approach for the Murray-Darling Basin Plan has shifted again, and now favours water-saving infrastructure over purchasing water rights. But is it the right move? The new scheme…

Deep cuts to environmental programs and staff predicted in today’s federal budget aren’t the only “green” cuts that Australians should be concerned about. The federal government is currently holding an…
Carp have spread throughout Australia’s waterways - but CSIRO is hoping to bring a new genetic weapon to bear on them.
A genetic modification that creates male-only populations could give us a new weapon against invasive fish such as carp that plague our waterways. “Daughterless technology”, which works by removing females…
Water management in the Murray-Darling may be inadvertently helping the common carp at the expense of native fish.
Wetlands and rivers need water – not least in the case of Australia’s biggest river system, the Murray-Darling Basin, which has been the target of an “environmental watering” plan designed to preserve…
