End date

Ongoing program dependent on annual renewals

Objectives of the program

This program aims to:

  • collect a robust set of data to describe non-urban diffuse sourced pollutants during storm events
  • provide information to third parties for validation of catchment models
  • provide insights into catchment processes influencing water quality models
  • foster partnership approach across organisations to ensure consistent approaches to water quality collection.

Regional and catchment or basin scale

Brief description of sampling locations

End of catchment and major sub-catchments - 29 gauging stations to gather data over a long period of time (30 years).

Single land use and small catchments - ‘mini’ gauging stations at 10 sites. Rising stage samplers may also be installed at some sites. 

Frequency of monitoring

Stream flow rates are calculated from continuously logged stream water level height measurements using site specific rating curves.

Water quality sampling is conducted throughout major flow events. It is also conducted on a monthly basis during periods of base flow conditions. Manual ‘grab’ sampling is conducted at monitoring sites:

  • where auto-samplers are not installed (or not functional)
  • on the falling stage at sites where rising stage samplers are installed
  • when sampling base flow.
