 FAQS

Where does our raw water come from?

Mount Isa’s raw water is supplied from either Lake Moondarra or Lake Julius. Lake Moondarra is 13 km downstream from Mount Isa and Lake Julius is more than 60km away. In normal conditions, all water is supplied from Lake Moondarra. However, when there is a drought, water is also supplied from Lake Julius.

What are blue-green algae?

Blue-green algae are naturally occurring bacteria found in rivers, lakes, soil, tree trunks and other places. In certain weather conditions, particularly involving long periods of hot dry weather, the blue-green algae “blooms” and there is a significant increase in the blue-green algae cell population. The recent local bloom has resulted in unprecedented levels of blue-green algae in Clear Water Lagoon, Lake Moondarra and Lake Julius.
