Hoover Dam – Intake Towers

The best way to view the pictures is to use the links below.

The pictures of this post show the Lake Mead side of the dam. At this side there are four intake towers, from where the water is lead to the turbines. Two towers on both side of the lake, so two in Nevada and two in Arizona.
◙ The main picture is a triptych with on the left side a Nevada Intake tower and on the right side an Arizona Intake tower. The picture on the right was taken 15 minutes after the picture on the right side, so you can tice the different time zones.
The centre picture of the triptych shows the two Intake towers on the Arizona side and the lake behind. You can easily see the difference of the highest water level and the present level of the water.
◙ The first workshop shows a wider view of the Intake Towers and Lake Mead behind with the strong colour-contrast on the rocks of the highest water level of the lake. You can read more about it in the info below.
◙ The second workshop gives a detailed view of the highest water level on the rocks around Lake Mead.

The Intake Towers

The Hoover Dam project includes four 103 m. high Intake Towers which stand in the deep waters of Lake Mead behind Hoover Dam.
They are reinforced-concrete structures, located above the dam, two on each side of the canyon. The diameter of these towers is 82 feet at the base, 63 feet 3 inches at the top, and 29 feet 8 inches inside. Each tower is 395 feet high and each controls one-fourth the supply of water for the powerplant turbines. The four towers contain 93,674 cubic yards of concrete and 15,299,604 pounds of steel.

Water level
The amount of electricity generated by Hoover Dam has been decreasing along with the falling water level in Lake Mead due to the prolonged drought in the 2010s and high demand for the Colorado River's water. Lake Mead fell to a new record low elevation of 326.63 m on July 1, 2016 before beginning to rebound slowly. Under its original design, the dam will no longer be able to generate power once the water level falls below 320 m. To lower the minimum power pool elevation from 320 to 290 m, five wide-head turbines, designed to work efficiently with less flow, are being installed and will be fully online by 2017. Due to the low water levels, by 2014 it was providing power only during periods of peak demand.
Control of water was the primary concern in the building of the dam. Power generation has allowed the dam project to be self-sustaining: proceeds from the sale of power repaid the 50-year construction loan, and those revenues also finance the multimillion-dollar yearly maintenance budget. Power is generated in step with and only with the release of water in response to downstream water demands. (Wikipedia)

I add the dark frame to the picture to give the posts a screen format of 1920x1080 pixels
The idea is that, if you use the links in the text, you have a full screen image of the picture with the photo in the centre of a dark screen.
This works with the browsers and screens I use, but I’m not sure that everybody will have the same result.
