31 January 2006 Mowamba Aqueduct Recommissioned the Mowamba

Date: 31 January 2006 Subject: Mowamba Aqueduct Recommissioned The Mowamba Aqueduct has been recommissioned concluding the temporary arrangement of water borrowing to the Snowy River via the Mowamba Weir. The recommissioning enables the 3 kms of the Snowy River closest to the dam to now receive the volume of environmental flows that was intended and described in the outcome of the environmental studies conducted during the Snowy Water Inquiry. The recommissioning of the aqueduct was undertaken in accordance with the provisions of the Snowy Water Licence. Those provisions are as agreed between the Commonwealth, New South Wales and Victorian Governments on corporatisation of the Snowy Mountains Scheme in June 2002. It now means that environmental flows to the Snowy River will be fully provided from Jindabyne Dam, as agreed to by the New South Wales, Victorian and Commonwealth Governments and as Snowy Hydro Limited has been directed. Those flows are now occurring. Snowy Hydro Limited Managing Director, Mr Terry Charlton, said: “The recommissioning of the aqueduct means that the Snowy River immediately downstream of Jindabyne Dam is receiving a higher volume of environmental flows. This is the outcome we all wanted.” “Further downstream at Dalgety and beyond, the environmental flow in the Snowy River is the same as the Snowy River was receiving before the recommissioning - and of course we will continue to additionally maintain a riparian flow down the Mowamba River below the Weir.” “Snowy Hydro has undertaken this work as part of our obligations under the Snowy Water Licence.” “Transferring an amount of water from the Mowamba River into Lake Jindabyne and then into the Snowy River is integral and critical to the water release arrangements that required the company to spend over $90 million upgrading and modifying the Jindabyne Dam, including works that enable us to release only oxygenated water from the top surface of the dam. This is the conclusion of a very desirable environmental outcome.” Mr Charlton added. For more information, please call: Paul Johnson Snowy Hydro Limited (02) 9278 1888 1 .

Between August 2002 and January 2006 environmental flows were released from the Mowamba River, a tributary below the Jindabyne Dam (Fig 1), to improve the ecological condition of the Snowy River. Although invertebrate communities were expected to recover via drift, the apparent lack of recovery2 has raised concern over the role of a weir on the Mowamba River acting as a barrier to the downstream migration of invertebrate fauna during environmental flows. Objectives 1. Determine if Mowamba Weir is a barrier to invertebrate drift and N particulate organic matter transport. 2. Evaluate options for managing Mowamba Weir to assist the recovery of macroinvertebrate communities in the Snowy River.

The Aboriginal Names of Rivers in Australia Philologically Examiped
The Aboriginal Names of Rivers in Australia Philologically Examiped. By the late REV. PETER 1I'L\.CPIIERSON, 1I'LA. [Read before the Royal Society qf N.S. W., 4 August, 188G.J IT is the purpose of this paper to pass in review the names which the aborigines of Australia have given to the rivers, streams, and waters generally of the country which they llave occupied. More specifically, attention will bo directed to the principles if discover able on which the names have been given. In this inquiry con stant regard will be had to the question whether the Aborigines have followed the same general principles which are found to pre vail in other languages of th"l world. -Without further preface, it may be stated that all available vocabularies will be searched for the terms used to designate water, whether in the shape of rivers, brooks, or creeks; expansions of water, as oceans, seas, bays, or harbours; lakes, lagoons, pools, or waterboles; swamps, or maJ"Shes; springs, or wells; rain, or ,vaterfalls; and any other form in which water is the important element. M, imitative of the sound of Waters. Words for Watel' containing the letter jJf. To make a beginning, let one of the imitative root words for water be chosen as the basis of experiment. There is the letter Jl, which represents the It1wnming sound pertaining to water, whether flowing in streams or moved by tides and winds in ocean expanses. In carrying out the experiment the method followed will be (1) to examine the vocabularies for root-words designating water in any of the shapes already indicated, and embodying in the present case the letter 1n; (2) to examine the gazetteers of the several colonies, to ascertain how the same letter is embodied in the actual names of rivers, streams, and waters generally; and (3) to compare the results with the root words for water in other part-s of the world.

Journal entry Restoring health to 04/11/2002 the Snowy River Why the Snowy needs restoring The construction of the Snowy Mountains Hydro-electric Scheme in the 1960s resulted in the diversion of 99% of the Snowy River’s natural flow at Jindabyne Dam. The result of this and other human activities has been a build-up of sediment in the river, weed infestation and reduced habitat for native flora and fauna. 1 Journal entry What’s so special about 04/11/2002 the Snowy River No other river in Australia flows through such diverse vegetation: alpine meadows and Snow Gum Woodlands near Mt Kosciusko, the Montane Grassy Woodlands and grassland of the MonaroTableland, tall wet mountain forests, Warm Temperate Rainforests of the lowland floodplain, wetlands and coastal scrubs and Littoral Rainforests on the coast at Marlo.% Much of the Snowy valley and its remnant vegetation and wetlands continue to be important resting, feeding and breeding areas for migratory species from tropical rainforests in south-east Asia and wetland birds from Russia, China and Japan.% The lowland floodplain of the Snowy River and its rich wetlands are the traditional land of the Krowathunkoolong clan of the Gunai (Kurnai) people. This area still retains cultural significance for these people. 2 Journal entry The History Jindabyne dam 04/11/2002 Dam Wall 1958 Outfall Snowy Mountains Hydro-electric Authority Act 1998 Snowy Water Inquiry Cobbon Dec 2000 Creek Snowy river Agreement of Victorian, New South Wales and Commonwealth Governments to increase the Mowamba aqueduct Snowy River flow by 21% within ten years of Cobbon corporatisation of Snowy Hydro-electric Authority, Weir and 28% in the longer term, as well as 70 gigalitres to the River Murray.

Long-Term Movements and Activity Patterns of Platypus on Regulated
www.nature.com/scientificreports OPEN Long‑term movements and activity patterns of platypus on regulated rivers Tahneal Hawke1*, Gilad Bino1, Richard T. Kingsford1, Dion Iervasi2, Kylie Iervasi2 & Matthew D. Taylor1,3 The platypus is a semi‑aquatic mammal, endemic to freshwater habitats of eastern Australia. There are gaps in the understanding of platypus movement behaviour within river systems, including spatial and temporal organization of individuals. We tracked movements of 12 platypuses on the regulated Snowy and Mitta Mitta Rivers for up to 12‑months, the longest continuous tracking of platypus using acoustic telemetry. Platypuses remained relatively localized, occupying 0.73–8.45 km of river over 12 months, consistent with previous tracking studies over shorter periods. Males moved further than females, and larger males had higher cumulative movements, suggesting a possible relationship to metabolic requirements. Platypuses moved greater distances on the Mitta Mitta River, possibly associated with impacts of altered fow regimes to their macroinvertebrate diet. Increased movements and diurnal activity during winter were primarily driven by males, possibly attributable to breeding behaviours, rather than increased costs of winter foraging. Evidence for relatively small movements has implications for declining populations, given areas of localised declines are unlikely to be supplemented by migrating platypuses, especially when dispersal is restricted by dam walls. Understanding platypus movement behaviour is pertinent for their conservation, as water resource development and habitat modifcation continue to reduce connectivity between populations across their distribution. Platypuses (Ornithorhynchus anatinus) occur mainly in creeks and rivers of eastern Australia, with an intro- duced population on Kangaroo Island1. Tey are primarily dependent on rivers and other water bodies, feeding exclusively on freshwater macroinvertebrates2, and using burrows on the water’s edge for resting and nesting3.

Snowy River Flow Response Monitoring and Modelling – Fish
Snowy River recovery November 2008 Snowy River flow response monitoring and modelling – fish Following construction of the Snowy Mountains Scheme between 1955 and 1967, flows in the Snowy River have been severely altered. To improve river health, water was released to the Snowy River via the Mowamba River as a result of the de-commissioning of the Mowamba River aqueduct. The Snowy River Flow Response Monitoring and Modelling program was established to assess the changes in river conditions that could be attributed to the new environmental water releases. This summary assesses the first stage Environmental Flow Regime (EFR) to the Snowy River from August 2002. Fish assemblages across the Snowy The fish in the Snowy River can be described as: • Consisting of two main groups above (upper) and below (lower) the major fish barrier of Snowy Falls (Figure 1). Upper and lower reaches refer to locations above and below Snowy Falls. • The fish in the upper Snowy River had a low abundance or absence of migratory fish (except eels) and a greater abundance of short-finned eel and trout. • The fish in the lower Snowy River comprised of a greater abundance of Australian smelt, congoli and long-finned eel. In both the upper and lower reaches, smaller differences were also observed between the main river sites of the Snowy River and the unregulated tributaries sites (Figure 2). These groupings can be explained by greater abundances of the fish identified in Figure 1. The EFR has had little influence on the fish of the Snowy River or the indices used to measure fish health, including native species richness, the proportion of individuals that were native species, population size structures, the abundance of trout, the proportion of individuals that were pest species or the abundance of each individual species.
