Information gathered through monitoring enables us to make informed water resource management decisions by providing answers to the following questions:
- How much water is there?
- Where is the water?
- What is the quality of the water?
- How much water is being used?
- What is the water being used for?
Surface water data is collected from around 780 monitoring sites across the state under Victoria's Regional Water Monitoring Partnerships' program.
The partnership approach allows data to be collected to a well-defined standard once, but used for multiple business needs, such as allocation management, compliance monitoring, flood warning, water resource assessment and river health management.
It provides a coordinated and efficient approach to the statewide collection of the information required for delivering a continuous program of water resource assessment for Victoria, as required under the Victorian Water Act 1989.
Around 40 organisations invest in the program and the Department of Environment and Primary Industries acts as both a partner and overarching program manager.
Water Quality Trends
Water quality is an important indicator of river health and river managers have a keen interest in knowing about trends in water quality through time.
To date, there have been three studies that have analysed long-term trends in river water quality across the state. The first water quality trend report was published in 1998 and the second in 2007.
Victorian Water Quality Trends 1991-2010 is the third long-term assessment of trends in water quality and focuses specifically on changes in water quality before and after 2005.
The three trend reports can be accessed through the Water Measurement Information System
