Summer recreational surveys showed that 38% (2016-2017) and 23% (2017-2018) of samples met the freshwater microbiological water quality guidelines prepared by the Ministry of Environment in conjunction with the Ministry of Health (MfE, 2003) and did not exceed the ‘Action’ level (>550 E.coli cfu/100mls).
The State of the Environment technical report showing the freshwater recreational monitoring results for 2017-2018 is available at www.trc.govt.nz/environmental-monitoring-technical-reports/
The Council also monitor ecological health at this site. We use an ecological index based on the macroinvertebrate communities (tiny animals including insects, crustaceans, mulluscs, worms and leeches) found in waterways to measure ecological health.
Macroinvertebrate data for Taranaki shown on LAWA may vary from some data reported elsewhere by the Taranaki Regional Council. This variation is because the level of macroinvertebrate identification used by the TRC has some minor differences from that used by other Councils and LAWA, affecting the taxonomic richness and % EPT taxa scores. Taranaki Regional Council also uses Macroinvertebrate Community Index (MCI) scores which have been modified to reflect the conditions experienced in Taranaki, while the scores shown here are based on the National MCI scores.

This dashboard shows the results from macroinvertebrate sampling at this site. It displays three ecological indicators: macroinvertebrate community index, taxonomic richness and percent EPT.
For sites where State is 'N/A' or Trend is 'Not Assessed', there are not enough data to calculate a State and/or Trend result. Click on an indicator to see the available historical data.
The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for macroinvertebrate data collection, processing of the data in the laboratory, quality control in the field and laboratory and the statistical analysis and interpretation of the results presented.

Macroinvertebrates are sampled at this site as part of council's stream health monitoring programme, as recommended by proposed national guidelines.
Macroinvertebrate sampling is done annually or more frequently at this site as recommended by proposed national guidelines. Therefore, data shown here follow current best practice guidelines.
This site is a hard-bottomed site and appropriate sampling protocols have been applied. Data shown here have been collected using current best-practice.
Macroinvertebrate sampling is done in riffle habitat at this site. Data shown here are therefore following best practice.
Macroinvertebrate samples are collected within the first two weeks after a flood greater than three times the median flow at this site. Proposed national guidelines suggest a minimum of two weeks 'stand-down' period after a flood greater than three times the median flow. Therefore, data shown here is not following best practice and conclusions based on this data need to be treated with caution.
Samples at this site have been processed following sampling protocol P1 (semi-quantitative - coded abundance). Data shown here is not following best practice, but are still robust.
Field data collected at this site had no quality control applied to it.
Data processed at this site has had one of the three Laboratory Quality Control Protocols (i.e., QC1, QC2,Q C3) applied. Data shown here is more robust than data with no laboratory QC applied.
