To this end, Environment Canterbury maintains a large network of several hundred water quality monitoring sites throughout the region, plus groundwater recorders and rainfall recording sites.
The Regional Council has also played a key role in the development, funding and implementation of the Canterbury Water Management Strategy. Launched in October 2009, the strategy is a vision for the sustainable use of water and a unique approach to complex water allocation and management issues.
Canterbury has been experiencing declines in water quality in recent years, with lowland streams having the poorest quality. Immediate steps to improve water quality, for instance by enhancing biodiversity along waterways, have been built in to the Canterbury Water Management Strategy from the outset.

Trend shows how the quality of water is changing over time. Depending on the sampling history duration, five and ten year timescales are available:
The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for data collection, laboratory analysis of samples collected and the statistical analysis and interpretation of the results presented.
If all Cawthron ticks are green, then you can trust this data. However, if one or more ticks are orange, then conclusions should be treated with some caution.
For more details on each tick, see our 'Can I Trust This Data?' Factsheet.
All samples were collected using approved field protocols and have been analysed in accredited laboratories. Therefore the data shown here has been collected and analysed following best practice.
