Watsit (water situation) report
type: Dataset
description: The water situation (or Watsit) report is a report we produce to oversee our water resources. It includes a summary of all the major sources of water we draw on to make sure your taps stay full of water 24 hours a day. Data such as weekly rainfall, regional reservoir stocks, river levels and demand is monitored allowing insight into our current position against historical and seasonal trends and fluctuations. The majority of the figures are produced either as a % of total capacity (in the case of reservoir stocks) or as Ml/d which is megalitres per day, note: 1 megalitre is equivalent to 1 million litres. Occasionally values are compared to the Long-term Average (LTA) The monthly Watsit reports can be downloaded below:
