Hello all,
I work for a private communications company. Some of our work is with the the Army Corps of Engineers. I did work in a control tower on a dam. Cut and paste the link below to See the Taylorsville dam.

I got to find out a lot on how some dams work.
A. In case the power goes out, a generator is used for backup.
B. Telemetry equipment is used to monitor such things as lake levels, gate levels, and water temperature.
C. The hydraulic pumps are used to open and close gates.
D. Large hydraulic pistons open and close the gates. The largest gates are at the bottom level. They are 6 feet by 15 feet big. The piston itself is 2 feet wide and 30 plus feet long.
E. The manifolds direct the hydraulic pressure where it needs to go. There are 15 gates at the dam.
F. During the winter, the water is cold top to bottom.. In the warm months the lake is warm on the top and cold on the bottom.
G. Gates are built at different levels.The reason for this is that fish need oxygen and correct river temperature at the tail water. Oxygen is always at the top. In the winter, upper level gates are open. When it warms up, various gates are open to get the right temperature.

I got to see my daughters twice on Saturday and that made me happy. My oldest went with me, the Baronette, and her daughter, to see the Baronette's son in CATS the musical. We had a good time. I'll try to put up Cats pictures on my next post.
Until then
TBB
