Baywide Water Quality Monitoring Program Milestone Report No.5 BAYWIDE WATER QUALITY MONITORING PROGRAM MILESTONE REPORT NO.5 MARCH 2010 EXECUTIVE SUMMARY Port Phillip Bay (PPB) is a large, shallow, almost landlocked bay under the influence of substantial urbanisation. Maintaining the key environmental processes of PPB is essential for sustainability. Water quality is important to a variety of assets, values and uses of PPB. There are several factors that can influence water quality in PPB, including: • Exchanges between the water column, sediment and atmosphere • Tidal flushing from Bass Strait • Sediment, nutrient and toxicant loads in freshwater inflows, particularly from the Yarra River • Discharges from industry and other users. These influences are reflected in the spatial and temporal variability of water quality parameters such as toxicants, nutrients and turbidity. This is the context for the Water Quality Baywide Monitoring Program (WQBMP) associated with the Channel Deepening Project (CDP). The WQBMP has been monitoring water quality in PPB on a monthly basis since November 2007, three months prior to the commencement of dredging activities for the CDP. Generally, the results of water quality monitoring in PPB over this period are within natural variability and the expected effects of the CDP, as determined by historical range and associated statistical analyses. For the most part, water quality was within levels of accepted guidelines. EPA identified no major areas of concern from assessment of the five month reporting period, August – December 2009. The results reported here are consistent with an understanding of water quality in PPB derived from earlier studies and other monitoring programs. Water quality in PPB during this period has been noticeably influenced by the increased catchment inflows as a result of rainfall exceeding the long term monthly average in September and November 2009. The results from this and other programs designed to monitor the health of PPB have indicated that changes in key environmental processes and assets are within the natural variability expected for PPB. Water quality throughout PPB remains as high as it has been for at least the past 20 years and is sufficient for maintaining assets and beneficial uses. 2 Table of Contents Executive Summary ............................................................................................................................................................ 2 1.

    June 1946 MEM. NAT. Mus. V1cT., 14, PT. 2, 1946. https://doi.org/10.24199/j.mmv.1946.14.06 THE SUNKLANDS OF PORT PHILLIP BAY AND BASS STRAIT By R. A. Keble, F.G.S., Palaeontologist, National Jiiiseurn of Victoria. Figs. 1-16. (Received for publication 18th l\fay, 1945) The floors of Port Phillip Bay and Bass Strait were formerly portions of a continuous land surface joining Victoria with Tasmania. This land surface was drained by a river system of which the Riv-er Y arra was part, and was intersected by two orogenic ridges, the Bassian and King Island ridges, near its eastern and western margins respectively. \Vith progressive subsidence and eustatic adjustment, these ridges became land bridges and the main route for the migration of the flora and fauna. At present, their former trend is indicated by the chains of islands in Bass Strait and the shallower portions of the Strait. The history of the development of the River Yarra is largely that of the former land surface and the King Island land bridge, and is the main theme for this discussion. The Yarra River was developed, for the most part, during the Pleistocene or Ice Age. In Tasmania, there is direct evidence of the Ice Age in the form of U-shaped valleys, raised beaches, strandlines, and river terraces, but in Victoria the effects of glaciation are less apparent. A correlation of the Victorian with the Tasmanian deposits and land forms, and, incidentally, with the European and American, can only be obtained by ascertaining the conditions of sedimentation and accumulation of such deposits in Victoria, as can be seen at the surface1 or as have been revealed by bores, particularly those on the N epean Peninsula; by observing the succession of river terraces along the Maribyrnong River; and by reconstructing the floor of Port Phillip Bay, King Bay, and Bass Strait, and interpreting the submerged land forms revealed by the bathymetrical contours.

  • VICTORIAN MULLOWAY TAGGING Newsletter- February 2019 Welcome to the Third Edition of the Victorian Mulloway Tagging Newsletter
    VICTORIAN MULLOWAY TAGGING Newsletter- February 2019 Welcome to the third edition of the Victorian Mulloway Tagging Newsletter. The purpose of this newsletter is to provide anglers with a summary of the tag and recapture data collected across the Victoria and interstate. This recreational tagging program is funded by the Victorian Fisheries Authority through Recreational Fishing License Fees and relies on the involvement of anglers. It’s been a very busy spring and summer, with plenty of Mulloway caught across the state. We have quite a few anglers on the waiting list to receive a tagging kit, so at this stage we unfortunately can’t recruit any more anglers. This is likely to change in the future however, so please stay posted! If you have a kit and find yourself no longer using it, please consider sending it back to us (see address on last page) and we can send it out to others. Rob Jeffery is one of our recently recruited taggers. He’s already been quite busy – this is Mulloway #1082 which was tagged a few weeks ago in the Glenelg River, at 79.5 cm. 1 Tagged Fish Since the last newsletter in May 2018, a further 148 fish have been tagged, bringing the current total to just under 300 (Figure 1). A huge thank you to all the anglers involved! Over the past few months we’ve seen Mulloway tagged in new areas of Victoria, including Western Port Bay (thanks to Dom Gillot) and the Moyne River (thanks to Peter McCallum). The majority of tagged fish however, are still being caught from the Glenelg River and nearby beaches in South East SA.

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.
