Part 3 [Hoover Dam]
The first tourist trap we came to was the Hoover Dam. We paid our money and took the dam tour. It was a worthwhile dam experience.
One of the tour guides talking about the diversion tunnels.
The diversion tunnel (on the Nevada side).
Making electricity, with the exception that "Nevada 3" had been pulled for repair. Sometime, around the 1980s I think they said, the elecricity produced and sold from the dam paid for the cost to have built it. But electricity was never the goal. It was always about the reservoir.
Walking to a vent on the downstream side of the dam. Tourism was considered at the time of construction. Finished tunnels, like the one above, were created for future tours. However, in the coming years, tours spread to the unfinished tunnels too.
The view from the vent.
Strings tied between bolts were once used to measure movement of the concrete blocks making up the dam. A broken string indicated the blocks had shifted away from each other; a bowed string indicated the opposite.
