Abstract: In the initial period after rehabilitation of the Ranger Uranium Mine most particulate matter released into Magela Creek will be wash load. 10% of the annual deposits on the backwater plain of the Magela Creek immediately downstream of Mudginberri Billabong will be fine-grained erosion products if the wash load exceeds 500tyr-1 (an average denudation rate of 0.3 mmyr-1). In the long term bed material load will be released into Magela Creek. The environmental impact of the deposits needs to be assessed.
