Mann577 - Mummel River at Cooplacurripa

Site Condition Summary

This site was just upstream of the junction of the Mummel and Cooplacurripa Rivers. The surrounding land was used for grazing.

The clearing of vegetation and cattle grazing had contributed to the degradation of the riparian zone. There was also some erosion due to the road. Within the river, the substrate was covered in filamentous algae and silt.

Water quality analyses indicated low nutrient concentrations. Other variables were within expected ranges.

AusRivAS assessments indicated the macroinvertebrate communities were similar to those predicted, with all O/E-Taxa values close to 1.
