Rainfall and run-off amounts vary widely from year to year and place to place, and we have a water management infrastructure with an accessible capacity of more than 80,000 GL to assist in redistributing water across time and space.
The past 5 years opened with widespread heavy rainfall and extensive flooding in Queensland, New South Wales and Victoria, and closed with some areas having record-breaking temperatures from October to December 2015.
The period since 2010–11 provided the first cooler than average year since 2001 (i.e. 2011), along with the warmest (2013), third-warmest (2014) and fifth-warmest (2015) years on record for Australia (BoM 2012,
Assessing water-related ecological processes and species populations further indicates the health of aquatic ecosystems. Processes and populations add a layer of assessment that integrates many of the individual parameters assessed in previous sections.
Risks from changes to land management arise mainly through potential hydrological and water quality changes, whereas those from water management relate to changes in the timing and nature of flows that may be beneficial or detrimental to aquatic ecosystem health.
