Monitored sites in the Ashburton River/Hakatere Catchment catchment
Filter sites by:
No sites found.
The local climate is temperate and characterised by hot dry summers and cool winters. Average rainfall ranges from over 3000mm to 738 mm. The upper catchment is mostly characterised by alpine rock and gravel, covered in dry grassland/tussock with low intensity landuse activities. Further toward the coast, the lower plains are under moderate-to-high landuse pressures from such activities as pastoral beef and sheep, dairying, cropping, urban and industry.
Seven sites are monitored on the Ashburton River as part of Environment Canterbury’s state of environment monitoring programme. The sampling site locations are representative of a range of land uses and catchment land covered in the Ashburton Zone. The river demonstrates low nutrient concentrations in the upper catchment, then becoming increasingly impacted from point and non-point source contaminants further downstream.
Increased demand for water and the effects from increasing agricultural activities are putting pressure on the Ashburton lowland water quality and aquatic ecosystems. The best water quality is often observed in the upper reaches where there has been little degradation and anthropogenic activity. The poorest water quality is typically found at sites closest to the coast where the river has been under pressure over the years from increasing landuse intensification, degradation and urbanisation.

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.

This data is not flow adjusted. National guidelines suggest that flow-sensitive variables are flow 'adjusted' before trend analysis. Therefore, any trends shown here may be affected by variations in flow across sampling occasions.
