1975 Las Vegas flash flood caused millions of dollars in damages

On July 3, 1975, the Thursday before the Fourth of July holiday weekend, a summer monsoon triggered a flash flood in the Las Vegas Valley.

While some gamblers sat unaware inside Las Vegas Strip casinos, floodwaters put Interstate 15 exits underwater and closed major intersections.

Raging water swept down the Flamingo Wash into the parking lot at Caesars Palace on the Strip, flooding hundreds of cars. Cranes had to be brought in to move the cars. Some vehicles were reported to be found miles away from Caesars.

Rushing water and erosion brought down telephone poles. Sewage plants were overwhelmed and fetid water was expelled through manhole covers.

Well owners were warned of contamination. Estimates of damage exceeded $4 million.

While directing traffic, two North Las Vegas city employees died after they were hit by a wall of water at Losee and Craig roads and swept away from their vehicle.

In the July 4, 1975, edition of the Review-Journal, a spokesman for the Las Vegas Public Works Department said it was the worst flooding in the area since 1955, which caused an estimated$3 million in damages.
