“There is no threat to the power grid and there is still power being generated,” said Jacklynn L. Gould, Bureau of Reclamation regional director for the Lower Colorado region.
The fire started around 10 a.m. and was extinguished about half an hour later, she said.
Videos posted to social media showed what appeared to be a fire or explosion in a building near the base of the dam.
A huge plume of black smoke billowed over the building.
The city of Boulder City announced on its Twitter account that the fire was extinguished before the fire department arrived. It referred additional questions to the Bureau of Reclamation and Hoover Dam.
The cause of the fire is being investigated.
Hoover Dam is located in the Black Canyon of the Colorado River on the Nevada-Arizona border.
According to the Federal Bureau of Reclamation, the dam is 726 feet high and 660 feet at its base, the length of two football fields measured end-to-end.
Up to 20,000 vehicles cross the 14-meter-wide crest, which is a National Historic Landmark, every day.
