Water Quality Bulletin 2 March 2011 D11/6241 Water Quality Bulletin 2 March 2011 Update on blackwater in the River Murray system The blackwater event in the River Murray, the Edward–Wakool, the Goulburn–Broken, Lower Darling, Murrumbidgee and Loddon rivers is continuing. The severity and extent of this event is due to the prolonged drought followed by widespread and persistent flooding, as a result there has been several sources of blackwater. Poor water quality from these floodplains continues to have a detrimental impact on the River Murray, however, the effect is no longer as pronounced as in previous weeks. Water quality information compiled by the Murray–Darling Freshwater Research Centre, (MDFRC) indicates that Dissolved Oxygen (DO) levels around Barmah-Millewa Forest remain stable at non critical levels. DO monitoring at Taylors Bridge Road, and in Barmah Lake, still exhibits DO concentrations at critical levels. This has been caused by a recent flood pulse through the Barmah- Millewa Forest. Downstream of Barmah in the River Murray between Echuca and Robinvale DO concentrations remain at critical levels. A slight recovery of DO concentrations has been observed between Robinvale and Mildura. The Goulburn River, Broken Creek and Gunbower Creek daily average DO concentrations have stabilised at non critical levels except at the monitoring site Condidorios which is continuing to record extremely low DO concentrations. Monitoring in the Coliban River, and Loddon River at Yando Road continue to record high DO concentrations at non critical levels. In the Edward River at Deniliquin, the DO concentrations have continued to increase to non critical levels. DO concentrations in the lower Darling River are stable at non critical levels, except at Wentworth the DO concentrations continue to be near critical levels. Frenchmans Creek inlet regulator is continuing to record critically low DO concentrations. Physical re-aeration over the inlet structure is having a moderate positive impact on DO concentrations along the remainder of Frenchmans Creek to Lake Victoria. DO monitoring on Lake Victoria shows that DO has increased to non critical levels. A continuing trend of increasing DO concentrations have been recorded in the River Murray above Waikerie in South Australia. At all sites downstream of Waikerie to the Lower Lakes, DO concentrations continue to be stable at near critical levels. To provide information on water quality during the blackwater event in the River Murray system the MDBA releases a dissolved oxygen level status map and weekly bulletin. This map visually represents the most recent dissolved oxygen levels measured within a 10 day period for sites monitored by numerous agencies. This information can be accessed at the MDBA website, http://www.mdba.gov.au/water/blackwater on a weekly basis.

    RIVERS AND THEIR IMPACT ON CADASTRAL BOUNDARIES By Peter S. Knights Land Investigation & Advice Section Office of Surveyor General Authorised by John R. Parker Surveyor General October 1996 SYNOPSIS A paper, demonstrating with the examples of case studies, the impact on cadastral boundaries of moving rivers. The paper emphasis the significance and importance of (a) the 1881 Order in Council by which land along some 280 rivers was permanently reserved , (b) the 1905 Water Act which clarified the term "bed and banks", and (c) the 1850 Separation Act which dealt with the Murray River as the State boundary. The role of the Surveyor General as an arbitrator is discussed as is the role of the surveyor as a planner and land manager. RIVERS AND THEIR IMPACT ON CADASTRAL BOUNDARIES The complexities and variations of the position of title boundaries abutting or adjacent to water courses are topics that often cause vexation to property owners, surveyors, solicitors and Crown land administrators. A surveyor, grappling with a re-establishment problem on the banks of the Freestone Creek (15 kilometres north west of Stratford) where shortages of 200 metres over entitlement are evident. Or wondering which of the many courses is the main flow of the Murray River through the Barmah Forest, must surely question the sanity or sobriety of the careers adviser of his/her High School who recommended surveying as a suitable and rewarding profession. There are so many variables that effect the problem that as a general rule each and every case must be treated on its own set of circumstances.

  • Estimating the Impacts of Climate Change on Victoria's Runoff Using A
    Estimating the Impacts of Climate Change on Victoria’s Runoff using a Hydrological Sensitivity Model Roger N. Jones and Paul J. Durack A project commissioned by the Victorian Greenhouse Unit Victorian Department of Sustainability and Environment © CSIRO Australia 2005 Estimating the Impacts of Climate Change on Victoria’s Runoff using a Hydrological Sensitivity Model Jones, R.N. and Durack, P.J. CSIRO Atmospheric Research, Melbourne ISBN 0 643 09246 3 Acknowledgments: The Greenhouse Unit of the Government of Victoria is gratefully acknowledged for commissioning and encouraging this work. Dr Francis Chiew and Dr Walter Boughton are thanked for their work in running the SIMHYD and AWBM models for 22 catchments across Australia in the precursor to this work here. Without their efforts, this project would not have been possible. Rod Anderson, Jennifer Cane, Rae Moran and Penny Whetton are thanked for their extensive and insightful comments. The Commonwealth of Australia through the National Land Water Resources Assessment 1997–2001 are also acknowledged for the source data on catchment characteristics and the descriptions used in individual catchment entries. Climate scenarios and programming contributing to this project were undertaken by Janice Bathols and Jim Ricketts. This work has been developed from the results of numerous studies on the hydrological impacts of climate change in Australia funded by the Rural Industries Research and Development Corporation, the Australian Greenhouse Office, Melbourne Water, North-east Water and the Queensland Government. Collaborations with other CSIRO scientists and with the CRC for Catchment Hydrology have also been vital in carrying out this research.

  • Chapter 3. Landscape, People and Economy
    Chapter 3. Landscape, people and economy Department of Environment, Land, Water and Planning 3. Landscape, people and economy Victoria’s North and Murray Water Resource Plan applies to surface water resources in the Northern Victoria and Victorian Murray water resource plan areas, and groundwater resources in Goulburn-Murray water resource plan area. This chapter provides a brief description of the landscape, people and economic drivers in the water resource plan areas. Working rivers The rivers of this water resource plan area provide many environmental, economic, and social benefits for Victorian communities. Most of northern Victoria’s rivers have been modified from their natural state to varying degrees. These modifications have affected hydrologic regimes, physical form, riparian vegetation, water quality and instream ecology. Under the Basin Plan it is not intended that these rivers and streams be restored to a pre-development state, but that they are managed as ‘working rivers’ with agreed sustainable levels of modification and use and improved ecological values and functions. 3.1 Features of Victorian Murray water resource plan area The Victorian Murray water resource plan area covers a broad range of aquatic environments from the highlands in the far east, to the Mallee region in the far west of the state. There are several full river systems in the water resource plan area, including the Kiewa and Mitta Mitta rivers. Other rivers that begin in different water resource plan areas converge with the River Murray in the Victorian Murray water resource plan area. There are a significant number of wetlands in this area, these wetlands are managed by four catchment management authorities (CMAs): Goulburn Broken, Mallee CMAs, North Central and North East and their respective land managers.
