Site Condition Summary

This site was within Dingo State Forest. The surrounding land was covered in native forest which extended to the riparian zone. There were some weeds in the riparian zone but the native vegetation was largely intact.

The instream habitat appeared undisturbed, and the water quality was good on all sampling occasions. Nutrient levels were below or close to detection limits and all other variables were indicative of excellent water quality.

All AusRivAS assessments for this site indicated high macroinvertebrate richness. All of the 23 individual assessments for either edge or riffle habitat gave O/E-Taxa values of 0.93 or greater, with most values >1.
