It outlines prudent approaches to normal dam surveillance and maintenance practice with a view to enhancing the long-term safety and operation of farm dams. Notwithstanding the detail in some sections, the booklet is not intended as a manual or as a source of detailed information to cover all possible eventualities. The successful planning, design, construction and operation of any particular dam will depend not only on application of general principles or guidelines, but also on a combination of technical factors which are peculiar to that dam and which will generally not be apparent in their entirety or significance to persons other than professionals who are experienced in this work, even for small farm dams. Therefore, while this booklet has been prepared in good faith, no responsibility is taken by its authors or the State of Victoria for any outcome of the application of its contents to any particular dam, whether existing or proposed. Readers of this booklet are further warned that application of its contents to any particular situation should not be attempted without advice from a suitably qualified engineer. Furthermore, in the event of any suspected, imminent or potential failure condition, expert advice should be sought immediately. Also notify the local Licensing Authority, Police, Department of Sustainability and Environment (Emergency Co-ordination Centre) and State Emergency Service as a matter of urgency.
