Assessment of River Health

AUSRIVAS – Australian River Assessment System

Predict aquatic macroinvetebrate fauna that would be expected

to occur in the absence of environmental stress

List of probabilities of occurrence of macroinvetebrates that

would be expected to occur at a test site if there were no impacts

The O/E ratio provides a measure of the degree to which the

macroinvertebrate fauna at a test site departs from that found at

reference sites.

The summed probabilities of the fauna expected to occur(E) is

compared to those actually collected (O).

Band OE

Scores

Band Name Comments

X >1.18 Richer than Reference More families than expected

Potentially biodiverse site

Possible mild organic enrichment

A 0.83-1.18 Similar to Reference Index value within range of the central 80% of reference sites

B 0.48-0.82 Significantly Impaired Fewer families than expected

Potential mild to moderate impact on water quality, habitat or both, resulting in the loss of families

C 0.13-0.47 Severely Impaired Considerably fewer families than expected

Loss of families due to moderate to severe

impact on water and/or habitat quality

D <0.13 Impoverished Very few families collected

Highly degraded

Very poor water and/or habitat quality



X - Richer than Reference A - Equivalent to Reference B - Significantly Impaired C - Severely Impaired D - Impoverished NS - Not Sampled Outside the experience of the model

Summary -River condition

Implementation of better riparian management practices, decreasing

agricultural run-off, providing adequate environmental flows especially during periods of low flow

Most sites in good to very good condition Number of sites undergo periodic episodes of slight impairment. Impacts appear to be due to insufficient habitat caused by high flows

or low substrate heterogeneity. Impacts at other sites due to habitat

degradation (unrestricted stock access, eroded banks, instream

sedimentation channelisation, and the presence of exotic weed

species in the riparian zone. Impacts from the physical degradation of instream and streamside

habitat can be compounded by poor water quality due to elevated

conductivity and turbidity levels.
