Inconsistent laws and penalties for water theft in the Murray-Darling Basin make compliance and enforcement especially challenging. But it doesn’t have to be this way.

Phosphorus and nitrogen contribute to water pollution and cause harmful algal blooms. New research shows how mats of floating flower beds can take advantage of these nutrients while cleaning the water.
Over 200 million tonnes of sediment are transported by rivers to the sea each year, the most widespread water contaminant in the country. Its devastating impact on marine life has to be reversed.
We sampled 118 rivers and creeks before and after the Black Summer bushfires, searching for platypus DNA. Here’s what we found.
Following historic drought in 2021, reservoir levels dropped down in the Hoover Dam on the Colorado River, which gets its waters from the melting snowpack from the Rocky Mountains of Colorado and Wyoming.

New research forecasts that climate change will make multiyear stretches with low snow levels more common across western North America – bad news for water managers, farmers, foresters and skiers.
Muddy water from debris flows like those in the Macalister catchment (West Gippsland, February 2007) can disrupt a region’s drinking water supply for years.

The federal government’s new $500 million funding package for the Great Barrier Reef seems predominantly focused on the tactics that are already being tried, without much success.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
Nitrogen pollution is one of the factors driving outbreaks of crown-of-thorns - giant starfish that devour the reef.

The latest Great Barrier Reef report shows some improvements to water quality over the past five years, but there’s still a lot to do on one particular problem: nitrogen.
Rainwater + hard urban surfaces = lots of runoff.

Built-up urban environments transform the resource of rainwater into wasted runoff. Low Impact Development mimics nature to help get stormwater into the natural water system.
