[
The river flooded in April 1929, following unusually heavy rains in northern Tasmania. After rainfall of in ninety minutes, the Briseis Dam gave way upstream of Derby, causing a torrent of water to rush down the narrow gorge of the Cascade River. At the time, the flood was the worst in Tasmanian history, lasting several days. Thousands of buildings were damaged and the death toll is variously reported to be between 14 and 22. After the 1929 Briseis Dam Disaster, a dam across the Cascade River was rebuilt in 1936 as the Cascade Dam.]
