Monitored sites in the Waingongoro River catchment
Filter sites by:
No sites found.
This catchment has been monitored since 1998. Ecological health has shown signs of significant improvement in the catchment especially at three Waingongoro River sites around Eltham. Recent riparian fencing and planting in the catchment is expected to result in better water quality as these areas become established, and as a result of the removal of the Eltham industrial and municipal discharges in 2010.
Including Egmont National Park, the Waingongoro catchment has a total of 1,219 km of stream bank. 57% of the stream banks have riparian vegetation that is either covered by a Taranaki Regional Council riparian management plan (53%) or within the National Park (4%). 82% of stream banks are protected by riparian fencing outside of Egmont National Park and another 4% are protected within the Park. There are stretches of stream bank that are both fenced and planted.
96% of the stream banks outside of Egmont National Park are covered by riparian plans (June 2017).
For all sites, the Council advises:
Avoid for three days after heavy rain, if the river is high, or if you cannot see the bottom clearly.

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.
