About the report
Yellow Water Billabong is a diverse freshwater wetland situated within the World Heritage listed Kakadu National Park. It is an important habitat for many birds and has become a major tourist attraction within Kakadu National Park. Commercial boat tours allow visitors the opportunity to view the abundant wildlife, especially the birdlife and saltwater crocodiles. Yellow Water is also a popular fishing spot for the both Traditional Owners and ecreational fishermen who are chasing the much prized barramundi.
Recently the Traditional Owners and Parks Australia North (PAN) raised concerns about the effects of boat traffic on Yellow Water with regard to erosion of the banks. A report by Cullen and Taylor (1988) was prepared for the Australian National Parks and Wildlife Service (now PAN) on bank erosion on Yellow Water Billabong. As part of the study for the report, a sacred area, Binji Water, was also visited to inspect and identify erosion occurring in a billabong with minimal boat traffic. The Cullen and Taylor (1988) report compiled a map of erosion locations on Yellow Water and made 10 recommendations to try and reduce bank erosion problems on Yellow Water. It is uncertain how many of these recommendations have been implemented. There is also a concern about possible damage caused by boat motors and propellers when the water levels are low towards the end of the dry season.
