显示更多 [+] 显示较少 [-]This dam has been classified as unsafe, emergency by the St Louis District as a result of the application of the following criteria: Spillway will not pass 10-year frequency flood without overtopping of the dam. The spillway is, therefore, considered to be unusually small and seriously inadequate. Overtopping could result in dam failure. Dam failure significantly increases the hazard to life and property downstream.
