The Tukituki at Walker Rd is a cobble dominated site. This area is popular with fishermen and also attracts swimmers and walkers during the summer months.
Elevated levels of bacteria are generally found after heavy and prolonged periods of rain causing increased surface runoff water to enter the river from the surrounding livestock dominated catchment.
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 sampling protocols follow current best practice. However, there have been inconsistencies in sampling protocols used during the past at this site (i.e., change from C1 to C3 in 2010). When analysing long-term data trends, however, this change in sampling methodology will need to be considered.
Macroinvertebrate sampling is done in riffle habitat at this site. Data shown here are therefore following best practice.
This council does not collect any macroinvertebrate samples for up to two weeks after a flood greater than three times the median flow as recommended by proposed national guidelines. Therefore, data collected at this site is following best practice.
Samples at this site have been processed following sampling potocols P2 or P3 and data have been processed following best practice.
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.
