River health data

We measure the health of waterways based on the key values they support, which reflect their environmental and social importance to the community.

These values are represented by fish, platypus, frogs, birds, macroinvertebrates, vegetation and amenity. View ratings for the current, 20 year and long-term condition of each key value within your catchment area.
