- Channel network evolution within the Narran Lakes was assessed using aerial photographs for the period of 1959 to 1998. Over this time, there has been a general reduction in network distribution and area which has been attributed to upstream and localized changes in landuse. Network changes have taken three forms: creation of new network, destruction of old network and migration of existing network. Of these changes, network destruction has dominated, with three times more channel area being destroyed than created over the period of study. As the Narran Lakes is a terminal wetland for the Narran River and is recognized internationally as an important migratory bird breeding habitat, the findings of this study have important management implications. In order to predict the impact of future landuse changes on the hydrologic functioning of this system, a comprehensive hydrologic model will be developed. Fundamental to this model will be the incorporation of knowledge on the evolution of regional water delivery networks.
