Cooby and Perseverance Dams Project – Reservoir and Water Quality ManagementResMix 5000 CC |
|
Cooby and Perseverance Dams provide source water for Toowoomba and surrounding areas and are also important recreational facilities for the region. Both the reservoirs experienced seasonal stratification resulting in low dissolved oxygen levels, high concentrations of metallic ions and periodic outbreaks of cyanobacteria. These factors combined to drive up treatment costs and in the case of toxic blue green algae, put recreational users at risk.
