💡 Tip: Double-click anywhere on a Plotly chart to reset zoom/pan to the original view.
You can also use the Autoscale button in the toolbar.

Getting Started…

The app interface is split into two main areas:

Right: Leaflet map

  • 🔍 Zoom and pan on the map to locate your monitoring site of interest.

  • 🔵 Click on a blue circle to select a site.

Left: Controls, plots and site information

  • Site Selected: Displays the name of the chosen site.

    • e.g., Barratta Creek at Northcote
  • Water Level Location: Displays the station ID and full name.

    • e.g., 119101A - Barratta Creek at Northcote (WMIP)

Noting not all water quality monitoring sites are equiped with in situ hydrographic monitoring equipment (i.e. water level sensors). In such cases WQI opt to utilise the closest most appropriate water level source as a proxy, primarily for sample timing and decision making processes.

It also provides valuable context while interpreting concentrations. Take care when interpreting charts utilising water level from alternate locations.

  • Select Pesticides for Graphical Display: Choose which pesticides to show in plots.

    • Plots will generate at the bottom of the left panel and stack vertically as more are added.
  • Select Date Range: Choose the time period for plotting data.

    • Selecting large time periods will result in longer load times.

Once a site is selected and parameters are chosen, the plots on the left load (scroll down). Use the instructions below to explore the charts.
