The run-off carried rubble to the Canyon Lake Dam creating a barrier in front of its spillway. [4]
The dam is owned and operated by the Bureau. The riverine reservoir it creates, the Black Canyon Reservoir, has a normal water surface of 1.7 square miles (4.4 km 2), [1] about twelve miles of shoreline, and an original maximum capacity of 44,700 acre-feet, reduced by siltation to about 31,200 acre-feet.

On March 12, 1928, the failure of the St. Francis Dam, constructed by the city of Los Angeles, caused a disastrous flood that killed up to 600 people. As that dam was a curved-gravity type, [21] similar in design to the arch-gravity as was proposed for the Black Canyon dam, opponents claimed that the Black Canyon dam's safety could not be ...

The partial failure of Minnesota’s Rapidan Dam sheds like on the almost 4,100 dams in the U.S. that are categorized at the same risk level and condition – or worse.
2000 Baia Mare cyanide spill: A dam failure resulted in the leak of 100,000 cubic metres of cyanide-contaminated water which spilled into the Someş and Tisza. Pollution flowed into Europe's second largest river, the Danube, and finally into the Black Sea, across six countries. Hungary asserted the spill killed 1,241 tonnes of fish in Hungary ...
