Itinerant Air-Cooled Greetings From Hoover Dam

[Amskeptic]

The above photograph I shot in 1982 with my Kodak Instamatic, the last time that the spillways spilled at the Hoover Dam. The below photograph was taken yesterday:





This is the bridge I was standing on that passes over the spillways just before they disappear into incredible tunnels that bring the excess water around the turbines and into the Colorado below:





I have bandwidth pigs to post later, but I am outta time just yet.
Wait here.

Why is that?

Most of the water goes thru the turbines. Only time they use the spillways is for maintenance or when there are high water events. The water levels have been very low for years so there has been no need.

Sufficient rains.
