DRAFT Waterway Health Strategy 0 Closing date for submissions: 30th September 2001 Comments to: Simone Gunn CCMA 64 Dennis Street Colac 3250 [email protected] 5232 9100 1 FOREWORD The Draft Waterway Health Strategy is an important step in continuing to build on the planning framework for integrated natural resource management in the Corangamite region. This Draft Strategy aims to take an integrated and whole of catchment approach to managing the region‟s waterways. Waterway management is a core responsibility of this Authority and as such it is important that our efforts are clearly and effectively directed. The Draft Waterway Health Strategy attempts to do this through identifying the condition of our waterways, the issues and proposing priorities for their treatment. The board encourages the input to the Strategy by our partnership agencies, stakeholders and the broader community. This is essential if the Strategy is to reflect the needs, priorities and aspirations of the whole community. I thank those involved in the preparation of this Draft and commend it to you for your consideration and input. Bob Carraill Chairman- Corangamite CMA I am pleased on behalf of the Authority‟s Water Resources Implementation Committee to present this Draft Waterway Health Strategy to the regional community. Improving the health of our waterways will require strong partnerships between the Authority and the community, and this Draft Strategy identifies many opportunities for such partnerships to flourish. The Strategy builds on the strong foundation of community work undertaken over the last four years to protect the health of the regions waterways, and provides a strong basis for community support for undertaking priority action over the next ten years. By establishing a benchmark of current waterway conditions, we can now move forward and focus on targeted actions to primarily protect our most valuable waterway assets and then to provide a framework for rehabilitating our more degraded waterways. The vision we have proposed best sums up what this Draft Strategy proposes for our waterways; “Working in Partnership, our community will maintain, protect and improve the regions waterways.” Importantly, the process for achieving this vision will be dynamic, and your input on the document is the first step in this evolution. I look forward to your involvement.

INTRODUCTION 2.1 The Need for a Strategy Our rivers, creeks, streams and wetlands – our waterways – are fundamental to our very existence. Water regulates all human activities and is implicit in all life. Waterways, wetlands and their floodplains act as natural water filters, helping to protect the quality of water for the environment and for human consumption. The aesthetic beauty of our tree-lined rivers is an intrinsic part of the Australian landscape. The overall quantity and quality of water gives the Corangamite region a significant natural advantage over drier areas of the state (CALP, 1997). Our waterways need our help. Recent assessments of the region‟s waterways found them in poor to moderate condition. Problems include loss of flora and fauna along stream banks, reduced water flows, deteriorating water quality, sedimentation, erosion and salinity. Our waterways have been substantially changed since European settlement by clearing of catchments for agriculture, intensive use of floodplains, draining of wetlands and development of water resources. A waterway is a function of its landscape, continually changing according to variations in the topography, climate, geology, vegetation, and land use. Improving the health of our waterways can only be achieved by the collective efforts of the entire regional community working together to rehabilitate both the land and waterway environments. Figure 2 View from Red Rock scenci lookout- Lake Corangamite Catchment In recent decades, the community has recognised the need for action to achieve integrated catchment management and the evolution and continued success of the Landcare movement has pioneered this approach. The emphasis for much of this work has focused on catchment or land based issues, with less focus on those issues directly relating to waterways. Consequently, many of our waterway problems have remained untreated and in some cases they have worsened. We now acknowledge the need to concentrate on the waterways themselves, for we cannot just rely on other works, which might be implemented in the catchments. This Draft Strategy for waterway health complements other regional strategies and plans designed to improve the management and enhancement of all of our natural resources. It focuses on developing and implementing actions that will directly maintain or improve the waterway environment, including the water, the bed, the banks and the streamside or „riparian‟ zone. Its scope includes rivers, creeks, streams, watercourses, tributaries and wetlands, however, as wetlands are such unique feature of the landscape, their management will be covered in more detail through prescriptive plans in the future. This Draft Strategy includes both strategic and operational recommendations relating to the improvement of waterway health. In addition to strategic recommendations, Action Plans have been developed for each of the key waterway systems in the region. These Plans provide a more detailed guide to the recommended works required
