Understanding units

Flow is generally reported as mega litres per day (ML/day),  1,000 ML/day is equivalent to 11.57 cubic metres per second (cumecs).


River flows and lake levels can change rapidly in Tasmania, because of rainfall and inflows throughout the state and the operational requirements of hydropower stations.

Hydro Tasmania is unable to guarantee or provide predictions about river flows or lake levels.

People using rivers and lakes for recreation should exercise caution.

For up to date information on flood warnings in Tasmania please visit the Bureau of Meteorology’s Tasmanian flood warning centre.
