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.
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.
