Maps: 1 Final recommendations omitted A1—A17 Victorian heritage rivers omitted INTRODUCTION The Land Conservation Council, Victoria - established by the Land Conservation Act 1970 - carries out investigations and makes recommendations to the Minister for Conservation and Environment on the use of public land in order to provide for the balanced use of land in Victoria. In making its recommendations, Council must have regard to both the present and future needs of the people of Victoria, in relation to criteria emphasising the need to protect significant conservation and recreation values. Council has also taken the view that it must achieve a balance between these and other community needs of public land seen from local, regional, State, and national perspectives. As part of this, it must provide for legitimate uses such as water use, the harvesting of forest produce and mineral extraction. Under its Act the Council is required to take into account the social and economic effects of its recommendations, and that has been done for this Investigation. Rivers and Streams Investigation In June 1987, the government directed the Land Conservation Council to conduct a Special Investigation of Victoria’s Rivers and Streams, in accordance with the following Order in Council: ‘Under Section 8 of the Land Conservation Act 1970 the Council is required to carry out an investigation of the scenic, recreational, cultural and ecological values of rivers and streams in Victoria, and to make recommendations on the use of these rivers and how their identified values can best be protected.’ Notices announcing the commencement of the Investigation were published in the Victoria Government Gazette and in Victorian newspapers in November 1987. In September 1989, the Council published the ‘Rivers and Streams Special Investigation - Resources Report’, which described the natural, cultural heritage, recreational, and scenic values of Victoria’s rivers and streams. Its purpose was to ensure that everyone who had an interest in the future use of our waterways and their catchments could obtain and study the basic information that the Council itself studied, and provide a submission on the report and its contents. The Council then formulated its Proposed Recommendations, and published them in November 1990 to provide a basis for public comment. Copies were distributed to all who made submissions on the Resources Report. A further submission period followed, and a list of those who made submissions is provided in Appendix I. Council’s response to submissions is given below. These Final Recommendations are the next stage of the process followed by the Council in accordance with the Land Conservation Act 1970. They will be presented to the Minister for Conservation and Environment for consideration by the government. Recommendations approved by the government will be implemented by the relevant land and water managers. The Council’s role is public land use planning; it does not have a role in ongoing management, beyond proposing broad management guidelines that are intended to clarify recommendations for the use of land. Availability of submissions Submissions received by the Council are available for inspection at the Council’s offices. Reasons for this Investigation Clean water, along with clean air and food, are fundamental to society. For thousands of years humans have sought to control the flow of rivers to our direct advantage. As a result, dryland areas have bloomed, floods have been reduced, and we have developed cities and industries that utilise large quantities of water. Hydro-electricity resources have also been developed. Societies are now recognising, however, that these benefits have had costs for the rivers. This century - with the advance of concrete technology, heavy earth-moving equipment, high-capacity pumps, and the availability of capital - changes to rivers, wetlands, and ground-water tables have taken place at an unprecedented rate. While Victoria has enjoyed the benefits of water resource development and the resultant economic growth, this growth has not been without adverse environmental and economic impacts. Construction of numerous weirs and dams has substantially changed the flow of many rivers. Rather than reflecting natural processes, river flows increasingly reflect human requirements, and as a result many natural systems have been put at risk. Our rivers have also been adversely affected by the discharge of a variety of effluents arising from off-stream domestic, industrial, and agricultural uses of water. Land use practices also have an impact. For example, land degradation, the addition of increased amounts of sediment to streams, and dryland salting have resulted from past land use. The salt not only makes an affected area unsuitable for agriculture but also adds to the salt load of the river, decreasing its suitability for irrigation or domestic consumption further downstream. Collectively, land uses, polluting discharges, and flow regulation have often reduced the scenic, recreational, ecological and cultural heritage values of rivers. They may also have economic implications where they restrict the downstream use of water, or affect the sustainability of important industries, or the attractiveness of areas with significant recreational or tourism values. The availability of water, which with minimal treatment is suitable for drinking, is becoming a pressing issue around the world. Debates in Australia reflect differences of opinion over the appropriate use of water and surrounding land. The flooding of Lake Pedder and the proposed flooding of the lower Gordon and Franklin Rivers in Tasmania became major issues. In Victoria, controversies over proposals to dam the Murray at Chowilla, to build a storage at Yarra Brae, and to divert the Aberfeldy at Donnelly Creek are reviewed in Dr J. Powell’s 1989 book ‘Watering the Garden State’. This work also discusses the 1964 proposal to divert Big River water to Melbourne, resulting in Premier Bolte’s pronouncement that not ‘one drop’ of water would cross the Great Dividing Range. More recently, plans to dam the Mitchell River at or below Angusvale and proposals to extract additional water from the Snowy River have aroused concern. The debates have emphasised the need to consider all values, be they economic return, flora, fauna, scenery, recreation, or cultural heritage, when determining appropriate water and associated land use. Increases in population and leisure time are likely to place greater demands on public land and resources, as people seek those recreational opportunities provided only by public land.
