Scenes from CSOonline's tour of Hoover Dam security operations.

Power Center

Hydro-electric generators at the Hoover Dam.

Down Below, Where Tourists Don’t Go

The dam holds back the water of Lake Mead and is the focal point of security efforts. Seen from the bottom of the facility, an area off-limits to tourists.

Under The Bridge

The under-construction Hoover Dam Bypass can be seen on the approach to the dam, just past where traffic slows on the approach to the security checkpoint.

One of Many Security Layers

Cones like these were evident along the approach to the dam, as were other barriers.

Traffic Control

Vehicles pass over the dam. Luggage-carrying buses and several kinds of trucks are prohibited from using this road due to security concerns.

You’ve Been Warned

Signs throughout the area remind tourists that security is present.

Tools of the Security Trade

Vehicles outside the Hoover Dam police station. Much of the substation in the background is inactive but remains as a historical feature. These areas are constantly watched from the screens of the security command center.
