Attitudes and Policy Responses to Australian Farm Dam Safety Threats: Comparative Lessons for Water Resources Managers

The safety of medium- and large-scale dams is addressed in many countries, but limited attention is paid to problems associated with smaller farm dams, particularly potential cumulative threats posed in larger catchments. Farmers in Australia often overlook the common law obligation to review and design dams in line with current standards. The result is downstream communities, property and environment placed at risk. This paper demonstrates the significance of this problem with case studies undertaken in policy-absent South Australia, policy-driven Victoria and policy-strong New South Wales, including empirical evidence on attitudes and responses of landholders and key policy actors. This demonstrates need for supervision of small dams. Tasmania is included as a case study as it represents a policy-model state on how this can be best achieved in line with international best-practice. The four cases provide useful comparative lessons. Policy guidelines applicable to any jurisdiction are included; their application is illustrated with the case studies. The paper considers the policy implications of these lessons for Australia in particular and the world in general.
