Appendix 1. Overview of Lake Eyre Basin Rivers Assessment programThe Lake Eyre Basin Rivers Assessment, established under the Lake Eyre Basin Intergovernmental Agreement (2000), was developed to: report on the condition of rivers and catchments within the Basin; promote and facilitate long-term monitoring of river conditions in the Basin; and promote and facilitate river research in the Basin. The main activity of the Basin Rivers Assessment program has been a river monitoring progam that has been conducted since 2011 based on an implementation plan established in 2009 (Kiri-ganai Research 2009). Under this monitoring program, data concerning hydrology, water quality and fish communities of over 50 waterholes across the Basin has systematically collected, collated and analysed for the past six years.

The methods for the Lake Eyre Basin Rivers Assessment monitoring program were developed in 2010/11 following the decision to commence ‘no regrets monitoring’ with a set of key indicators: hydrology, water quality and fish. The development of these methods built on the work of the Lake Eyre Basin Rivers Assessment planning in 2009 (Thoms et al. 2009) and the ARIDFLO project (Costelloe et al. 2004) and also incorporated survey methods used by the South Australian and Queensland governments. Key methods for fish and water quality are documented in McNeil & Cockayne (2011) and in the first annual monitoring report from the project (Cockayne et al. 2012). The first round of Lake Eyre Basin Rivers Assessment field monitoring resulted in slight adjustments of the monitoring methodology for subsequent rounds as reported in Cockayne et al. (2013).

The monitoring program methodology was developed to be consistent with the Strategic Adaptive Management Framework (subsequently finalised in Kingsford and Biggs 2012), abbreviated as SAM. This included specifying indicators of river and catchment health (condition) in the form of hypotheses. For each indicator, there are attributes that can be measured and compared to critical threshold values. The thresholds are referred to as Thresholds of Potential Concern (ToPCs). Draft ToPCs were proposed with a view to identifying when significant changes may be occurring.

The current monitoring program involves field visits to fixed monitoring sites (waterholes) where fish, water quality and flow/drying data are collected. The program also involves collating and presenting data from government river gauging stations which are monitored by the Northern Territory, South Australian and Queensland governments. Some monitoring sites are co-located with a flow gauging station, but most are not (Duguid et al. 2016).

The monitoring sites are waterholes in the major river systems of the Basin: Georgina, Diamantina, Cooper, Finke, Macumba and Neales. The sampling strategy adopted involves monitoring representative ‘fixed’ sites with a focus on permanent and near-permanent aquatic refuges (i.e. waterholes). Site selection prioritised waterholes with historical monitoring and those with government river-gauging stations. Some less persistent waterholes were also selected to provide a broader geographic spread of monitoring sites and to incorporate a wider range of habitats than if only permanent sites were selected. As a consequence, some sites were completely dry on some survey trips. In such cases, substitute sites have been surveyed. Some contingency sites have also been identified, which are to be monitored if fixed sites are inaccessible. Each contingency site is in the


same catchment area as a particular fixed site or has similar environmental characteristics. This method allows for additional sites to be selected in the field when required (N.B. a contingency site becomes a substitute site once it has been monitored). In some catchments, knowledge of the waterholes has improved considerably as a result of this monitoring program, leading to the deselection and replacement of some initial fixed sites.

The Lake Eyre Basin Rivers Assessment monitoring program involves surveys of the selected waterholes at least once a year (unless inaccessible due to flooding), with some sites surveyed twice a year. Fixed sites are all scheduled for a monitoring visit each autumn, and a subset of these sites is also monitored in spring. This approach enables consideration of ecological seasonality, particularly for fish population dynamics, as discussed further in McNeil and Cockayne (2011) and in Cockayne et al. (2013). It involves a trade-off between the total number of sites and the sampling frequency. However, by not sampling all sites twice a year, more sites can be monitored at least once a year. This has benefits for the spread and representativeness of sites and should improve the power of some analyses.

The monitoring program collects and collates hydrological and water quality data from a range of sources using various methods, as different data types are available at different locations. Some data is continuous data from sensors with either data loggers or telemetry (i.e. data transmitted to government databases). Other data is only collected on site visits during monitoring survey trips. Some data is relevant at local and regional scales, while other data has most relevance at the scale of individual waterholes. This variety creates some complexity in reporting methods and results.

Hydrology data collected under the monitoring program consists mainly of:

river flows (flow height)

water levels in waterholes (i.e. when they are below their cease-to-flow level)

waterhole physical dimensions (depth, length/perimeter, cease-to-flow control location, and bathymetric survey/mapping).

Figure 1 and Table 1 in the following pages show all sites where flow data is recorded for Lake Eyre Basin Rivers Assessment. Futher information is available in the Lake Eyre Basin Rivers Assessment 2014/15 Monitoring Report (Duguid et al. 2016).

Data on water levels in waterholes improves understanding of waterhole persistence and drying rates and can be correlated with fish and water quality data to interpret ecological dynamics. Water level data can also contribute to understanding the sources of water (e.g. river flow, groundwater, local rainfall, minor river flows and tributary flows) and water losses (e.g. evaporation, transpiration, extraction, stock drinking, draining into soil and aquifers). Waterhole water level data is obtained from in-water data-logging instruments at the monitoring sites where these are installed.

Water quality data is derived from three major sources:

hand-held sensors used to take measurements during survey visits to Lake Eyre Basin Rivers Assessment monitoring sites (temperature, EC, turbidity, pH, dissolved O2)

in-water data-logging instruments (CTD-Diver) at Lake Eyre Basin Rivers Assessment program monitoring sites


(recording EC and temperature, as well as water level)

telemetered in-water data-logging instruments at some telemetered gauging stations (EC and temperature, as well as water level).

A summary of the water quality statistics used to inform this report are in Tables 2, 3 and 4.

Fish community data is collected through passive trapping using fyke nets, set overnight.

At some sites, fyke netting is supplemented with bait traps and/or seine netting and/or visual survey and/or dab-netting. The effectiveness of the strategy is supported by extra-sampling undertaken at some Queensland sites to test aspects of the methods (reported in Sternberg et al. 2014). All fish are identified and counted and measurements are recorded for total length of 100 individuals of each species. Information on reproductive status and disease is recorded. The presence of large crustaceans (e.g. inland crab, yabby, redclaw, freshwater prawn) and some other macroinvertebrates are recorded opportunistically. Fish community sampling has been undertaken twice yearly since 2011 with between 44 and 55 sites sampled across these years (Cockayne et al. 2012; 2013, Mathwin et al. 2015, Duguid et al. 2016). Each sampling round has consistently found a greater range of distribution of fish species than previously understood and has increased a greater baseline understanding of this distribution in relation to wetting and drying cycles. There has also been a greater appreciation of the spread of exotic and translocated species.

Figure 2 and Table 5 in the following pages show the fish monitoring sites for Lake Eyre Basin Rivers Assessment in 2015/16.

2 Is this the first flow event to exceed 150,000 megalitres per month within the last two years?(If ‘Yes’ go to 3; if ‘No’ go to 4)

3 When calculating BCG Tier scores use the dispersal phase descriptors.

4 This is a subsequent flow comprising a part of a supraseasonal flood event. When calculating BCG Tier scores use the boom phase descriptors.
