There are different categories in the Crowdwater App:

  • Virtual Staff Gauge: For water level observations if there is no staff gauge installed in the stream.
  • Physical Staff Gauge: Water level observations based on a staff gauge (ruler) installed in the stream.
  • Soil Moisture: Moisture status for any unsealed surface.
  • Plastic Pollution: Observations of plastic in a water body or on the shore.
  • Temporary Stream: The flow state of streams that sometimes dry up.
  • Stream Type: General information for a watercourse, including information on the water quality.
