Outback NSW residents are frustrated, fed up and worried about their drinking water after the biggest fish kill on the Darling-Baaka River in memory.

Millions of native fish have washed up dead on the river at Menindee and downstream towards Pooncarie, in the state's far west, since late last month as floodwaters receded and the region was hit by repeated heatwaves.
