Abstract The integrated river or catchment-based management of land and water resources is
generally regarded as the most effective way to address intertwined problems such as eutrophication and
progressive land degradation. Solving these problems requires assessing the ecological and socioeconomic
outcomes of the remediation measures and analysing the measures’ performance with regard to a defined
set of objectives. Following the recent changes in water management legislation in New South Wales
(NSW, Australia), both these components now have to be integrated within a seamless framework. The
legislative changes (e.g. the Water Management Act 2000) tackle problems related to sharing water across
government and water management boundaries and address combined water-land management. In this
paper we tackle the water quality issue related to land erosion and the subsequent washing of nutrient
loads into surface water using the example of the Ben Chifley Dam (BCD), which is located on the
Central Tablelands of New South Wales, Australia. Eutrophication in the dam has caused the increased
occurrence of blue-green algal blooms in the past, which impair the riverine ecosystems and the
downstream water uses. The BCD Steering Committee, a community institution in charge of catchmentbased
management, has to decide how to the use the funds available to tackle the problem. The
environmental modelling and decision aid approach described has been developed to help the Steering
Committee assess the ecological and economic impact of the measures and to identify subcatchments
where the measures are likely to have the greatest effect. Throughout the paper the strategies applied in
the EU and NSW to tackle water quantity ands quality issues are discussed.
