Programme overview
Rivers and streams have important natural and cultural values. They are also important resources for drinking water, farming, recreational activities, managing storm water and industrial use. Human activities and discharges to rivers from various sources affect the quality of water and its suitability for human use and biodiversity.
Monitoring results and network
River and stream water quality is assessed at monthly intervals by measuring a range of physicochemical and microbiological variables. Click the links below or use the ‘Results’ dropdown menu in the navigation menu at the top of the page to see key results for:
- Nutrients: Nitrogen & Phosphorous
- Microbiology: E. coli
- Sediment: Water Clarity, Suspended & Deposited Sediment
- Ecosystem health: Water Temperature & Dissolved Oxygen
- Supporting variables: pH & conductivity
Monitoring sites within each Freshwater Management Unit (FMU) are shown below. Drag and scroll on the map to move and zoom in on areas of interest and hover over a site circle for more information.
