The future outlook for the Murray-Darling Basin environment is extremely challenging and their will be no scope for environmental flows for the remainder of 2019 unless it rains, according to the Murray-Darling Basin Authority.

The Authority has cautioned there will focus on providing drought refuges and avoiding irreversible loss of species.

Moreover, the Authority warns that there are almost no reserves of environmental water in the northern basin and that, as a result some important wetlands and floodplain forests have not received water for long periods.
