EVALUATING PERFORMANCE: MONITORING AND AUDITING
121
Baseline; Monthly/ yearly (taxa and ecosystem specific)
Indicator species (e.g. algae, micro/ macroinvertebrates, fish, other vertebrates); refer to biodiversity management handbook
Indicator species (e.g. algae, macroinvertebrates, fish, larger vertebrates); refer to biodiversity management handbook
Flow regime alteration (see above—Hydrology)
Passage design and operation; organism passage and persistence upstream and downstream
Aquatic ecosystems— reference and impact sites (ambient)
Aquatic ecosystems—direct toxicity assessment
Aquatic ecosystems— environmental flows
Aquatic ecosystems— organism passage
Baseline (passage requirements of aquatic and riparian biota)
Baseline (hydrology; flow dependency of aquatic and riparian biota)
As appropriate for pilot plant/ bench test effluents
Baseline/seasonal (late dry season to determine water source(s) used by potential GDEs)
Indicator species of riparian flora/fauna—determine if groundwater/baseflow dependent ecosystem (GDE) (ground and surface water monitoring as well as water use by plants to determine if dependent upon baseflow or other water sources)
Riparian ecosystems— reference and impact sites (ambient)
Exploration/ feasibility phaseb

Minimal alteration of organism distributions. Organism passage rates unchanged.
Minimal alteration of flow regime, particularly base flows and timing and frequency of peak flow events. Flow dependent ecosystem status. Minimal alteration of organism distributions.
See above (hydrology, aquatic and riparian ecosystems)
