Water managers around Australia are currently considering various strategies to deal with water shortages. Many of these management actions have potential to impact water quality, through altering the nutrient balance within reservoirs and hence affecting nutrients available for cyanobacteria. Cyanobacteria blooms pose an increasing threat to water supplies, with economic, social and environmental costs of $150M pa in Australia. The project will provide tools to water quality managers to assess how changes to subtropical reservoirs, such as water recycling, catchment land-use changes and increased drawdown are likely to affect nutrient budgets and cyanobacteria blooms.

澳大利亚各地的水资源管理者目前正在考虑各种应对水资源短缺的策略。其中许多管理行动有可能通过改变水库内的营养平衡而影响水质，从而影响蓝藻可用的营养。蓝藻水华对供水构成越来越大的威胁，澳大利亚每年的经济、社会和环境损失高达1.5亿美元。该项目将为水质管理人员提供工具，以评估亚热带水库的变化，如水循环、集水区土地利用的变化和降水量的增加，可能会影响营养平衡和蓝藻水华。
