New aerial footage appears to show thousands of dead fish at Lake Pamamaroo in the Menindee Lakes System, near Broken Hill, nine months after a mass fish kill event on the nearby banks of the Darling River.

The Florida Keys is experiencing higher than usual fish kills this summer, but wildlife officials don't think it's part of a red tide or other type of algae bloom affecting other parts of South Florida.

The condition of the lake isn’t very good and it has the typical problems with high nutrient levels and depleted oxygen.
