Abstract: This paper presents some of the results of a case study investigating stakeholder involvement in surface water planning processes in the joint catchment of the Diamantina and Georgina Rivers in central Queensland. Historic withdrawals and allocation arrangements with pastoralists and the mining industry have recently been formalised through the Water Resource (Georgina Diamantina) Plan 2004 and the draft Resource Operational Plan 2005. This paper specifically investigates stakeholder perception of the role floods play in the viability of the region. The perceived importance of the floods to economic viability, ecological viability and social viability is discussed.
