Between December 2018 and January 2019, three mass fish death events happened along a 40km stretch of the Lower Darling River, downstream of Menindee Lakes.  Although this event occurred far from us in Victoria it was a highly public and very distressing event for everyone, seeing up to a million fish including 100-year-old Murray cod die in one of the biggest environmental catastrophes to hit the river.

The video linked to the title above and this one here help students understand the issues around what happened.  Note: views expressed are the opinion of the video producers not River Detectives or any participating CMA.  And a warning that some scenes could be distressing for students.
