Loss of water quality can adversely affect these uses and values. Management of the environmental quality of rivers and streams in the Bay of Plenty is guided primarily by the Regional Water and Land Plan (RWLP). Objectives, methods and policies in this plan, and in the regional plan for the Tarawera River Catchment, aim to provide for the maintenance and enhancement of water quality and quantity.
Water classifications are included in regional plans as a guide for issuing resource consents for activities that might affect waterways. There are 60 river and stream sites included in the Bay of Plenty's Natural Environment Regional Monitoring Network (NERMN) water quality module and NIWA monitors an additional six sites.
While there are significant improving trends, the water quality of many rivers and streams is deteriorating. The main indicators of this are nutrients, bacteria and suspended solids/turbidity.
This dashboard shows information on the data collected by the regional councils for water quality indicators, analysed as

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.

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.
