Site Condition Summary

The headwaters of the Kerripit River are in the Barrington Tops National Park. This site was approximately 5 km downstream of the Park boundary. Land adjacent to the site was used for grazing. The riparian zone consisted of mainly native species with little sign of disturbance.

Water quality at the site was good, with nutrient concentrations close to detection limits, and other variables indicative of a relatively undisturbed stream of this type.

AusRivAS assessments indicated both the riffle and edge habitats had a rich macroinvertebrate fauna, which contained animals from all the major taxonomic groups.
