Manning River

Mann572 - Manning River at Gloryvale Reserve

Site Condition Summary

Land adjacent to this site was covered in native forest. On the left bank, this had been partly cleared for a picnic and camping area. Both upstream and downstream, the primary land use was agriculture.

The water quality was good on both sampling occasions. Nutrient concentrations were low and other variables were within expected ranges. Nutrients and turbidity were slightly higher when sampled in Spring compared to the previous Autumn. This was due to rain and increased flow in Spring.

AusRivAS assessments indicated a rich macroinvertebrate fauna was present, with all assessments returning O/E-Taxa values >1.
