Here are some Water Quality Guidelines for your reference
As you can see, while there have been quite drastic increases and decreases, the levels of faecal coliform count have remained significantly lower than the maximum acceptable risk levels. To see the procedure we use for water testing, click here. Please remember to send through wildlife sightings in and around the river, as these are the best indicators of the health and ecological function of the ecosystem. Please submit sightings via iNaturalist.org with a photo and GPS point (or accurate location description) for us to download and include in our database.
