Low oxygen levels could again be a strain for Darling River fish, as high floodwaters move downstream into the Menindee Lakes. Hypoxic blackwater, which occurs naturally through the breakdown of organic matter, can create a deficient level of oxygen in the water during flooding events. In combination with any sudden temperature increase could create an inhospitable environment for fish.
