ISBN 0 7347 5710 7 Acknowledgements The Hawkesbury Nepean River Health Strategy has been developed by the Hawkesbury Nepean Catchment Management Authority. The development of the Strategy would not have been possible without enormous assistance from a range of contributors including people who live and work in all areas of the catchment. Contributors included farmers, commercial and recreational fi shers, bushwalkers, environment groups, Landcare, non-government organisations, community groups, individuals, staff from Councils and state government departments. While the Strategy was an organisation-wide undertaking, the bulk of the document was developed by HNCMA Catchment Offi cers, Ruth Williams and Paul Bennett. Numerous other staff assisted with the rapid assessment and technical panels and contributed local expert knowledge. Everyone involved in the development of the Strategy share a passion for the many creeks and rivers of the Hawkesbury Nepean catchment and its environment. Some of the community members who gave their time and eff ort are profi led in the CD and website. The profi les give a taste of the valuable contribution made by many people. The Hawkesbury Nepean CMA gratefully acknowledge the wealth of knowledge and enthusiasm brought to the development of the Strategy by all who were involved. iv HAWKESBURY NEPEAN CATCHMENT MANAGEMENT AUTHORITY MINISTER’S FOREWORD Hawkesbury Nepean The protection of our natural resources is a River Health Strategy responsibility that we all share and which will only be achieved if a dialogue between all sectors of The Hawkesbury the community is sustained.

The Hawkesbury-Nepean River Health Strategy is an integral part in the puzzle which the NSW Government is constructing to protect the river system, now and into the future. An integrated response is imperative if we are to confront the wide array of complex issues our environment poses. The strategy will provide us The Hon Ian Macdonald MLC with an invaluable ‘tool’ to meet these challenges Minister for Natural Resources in an intelligent, empowered and informed manner. I congratulate the Hawkesbury-Nepean Catchment Management Authority (CMA) for its hard work in developing this strategy. It will play a critical role in delivering many of the objectives of the State Plan. The NSW Government established 13 CMAs across the State in 2003 to ensure the involvement of local people in natural resource decisions. This strategy is another example of that system working.

HAWKESBURY NEPEAN RIVER HEALTH STRATEGY vii EXECUTIVE SUMMARY The rivers of the Hawkesbury Nepean catchment: • Supply drinking water for over 4 million people living in Sydney, the Illawarra and the Blue Mountains • Help generate over $1 billion annually in agriculture production (12% of all NSW’s agriculture) including much of Sydney’s fresh vegetables, fl owers and fruit. • Support a $6 million a year commercial fi shing industry • Support 43,000 recreational fi shers • Supply 80% of the sand and gravel used in Sydney’s construction industry worth an estimated $100 million a year • Attract more than 10 million visitors to the catchment each year generating over $60 million annually in tourism and recreation • Provide 23% of NSW’s electricity using water from catchment’s rivers • Supports an extensive underground coal mining industry • Help sustain the environmental values of the 1 million hectare Greater Blue Mountains World Heritage Area Pressures on the rivers of the Hawkesbury Nepean catchment The rivers and riparian lands of the Hawkesbury Nepean are experiencing signifi cant pressure from urban and rural residential development; extraction of water for metropolitan water supply and agriculture; nutrient input from sewage treatment plants, on-site sewage systems and run-off from agricultural and urban areas; clearing of riparian lands; and altered aquatic habitats that support fewer species. The challenge exists to balance these pressures of development and to protect the environment. The fact that nearly 50% of the catchment is protected in National Parks and drinking water catchments is providing some protection for key waterways and reduces these pressures in some areas. But the symptoms of a stressed river system are obvious across the catchment.
