Waipapa at Landing

The Waipapa Stream is fed by Lake Manuwai and flows east out into the Kerikeri Inlet. The stream passes through a mixture of land use types, including pastoral, horticulture (orchards) and lifestyle blocks. The underlying geology is predominantly acidic volcanic.

The Waipapa River site is located at the Waipapa Landing boat ramp and picnic area near Kerikeri.

Scientific Indicators
Scientific data for this site

This dashboard shows information on the data collected by the regional councils for water quality indicators, analysed as state and trend.

  • State

    State shows how the median of samples from this site compares to other sites.

    This site is a Lowland Rural site. Currently showing the state of this site compared to:

  • The state is also represented by comparison to the National Objectives Framework (NOF) in the National Policy Statement for Freshwater Management 2014  for some indicators.

  • Trend

    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 state is also represented by comparison to the National Objectives Framework (NOF) in the National Policy Statement for Freshwater Management 2014  for some indicators.


Can I trust this data?

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.

Data Collection

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.

State

All samples were collected using approved field protocols and have been analysed in accredited laboratories.

Trend - SAMPLING FREQUENCY

Samples are collected monthly at this site. Proposed national guidelines suggest monthly sampling is required for trend analysis. Therefore, any trends shown here are based on best practice in terms of sampling frequency.

Trend - Adjustment for flow

This site is not sampled during high flows so the data shown only represents base flow conditions. Proposed national guidelines recommend sampling during both low and high flows to get a full picture of water quality at the site.

What do the icons mean?

It is important to note that changes to the National Policy Statement for Freshwater Management 2014 were announced in August 2017. The changes have removed the below set of criteria for E. coli, and any reference to this use of water (i.e. occasional immersion). The new criteria, effective from 6 September 2017, are for the use of water for swimming and other full contact, sustained exposure activities (diving, surfing etc). The data on LAWA has not yet been updated to reflect the new requirements.

The bands for E. coli are as outlined in the NOF for freshwater:

A
Water quality is considered suitable for the designated use. People are exposed to a very low risk of infection (less than 0.1% risk) from contact with water during activities with occasional immersion (such as wading and boating).
B
Water quality is considered suitable for the designated use. People are exposed to a low risk of infection (less than 1% risk) from contact with water during activities with occasional immersion (such as wading and boating).
C
Water quality is considered suitable for the designated use. People are exposed to a moderate risk of infection (less than 5% risk) from contact with water during activities with occasional immersion (such as wading and boating).
National bottom line: Annual median 1000 n/100mL.
D
Water quality is not considered suitable for the designated use. People are exposed to a high risk of infection (greater than 5% risk) from contact with water during activities with occasional immersion (such as wading and boating).

What do the icons mean?

The bands for Total Oxidised Nitrogen are as outlined in the NOF for freshwater:

A
Water quality is considered suitable for the designated use. High conservation values system. Unlikely to be effects even on sensitive species.
B
Water quality is considered suitable for the designated use. Some growth effect on up to 5% of species.
C
Water quality is considered suitable for the designated use. Growth effects on up to 20% of species (mainly sensitive species such as fish). No acute effects.
National bottom line: Annual median 6.9 mg NO3-N/L. Annual 95th percentile 9.8 mg NO3-N/L (milligrams nitrate-nitrogen per litre). Note 1 mg/l = 1 g/m3
D
Water quality is not considered suitable for the designated use. Impacts on growth of multiple species, and effects starts approaching acute impact level (i.e. risk of death) for sensitive species at higher concentrations (>20 mg/L).

Data Collection

Macroinvertebrates are sampled at this site as part of council's stream health monitoring programme, as recommended by proposed national guidelines.

Sampling - Frequency

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.

Sampling - Protocols

This site is a hard-bottomed site and appropriate sampling protocols have been applied.  Data shown here have been collected using current best-practice.

Sampling - Habitat

Macroinvertebrate sampling is done in riffle habitat at this site. Data shown here are therefore following best practice.

Sampling - Stand-down period

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.

Processing - Protocol

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.

Quality Control - Field

Field data collected at this site had no quality control applied to it.

Quality Control - Lab

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.
