About Hoover Dam
The Hoover Dam is located on the Colorado River between Arizona and Nevada. The dam is located 30 miles southeast of Las Vegas. The dam created Lake Mead, which is named after the man who oversaw the dam's construction, Elwood Mead. Although it has since been surpassed, the Hoover Dam was the largest concrete structure and the largest electrical power producing plant when it was completed in 1935.

If you had 13 to 1922 it would equal 1935. So Patrick William Tierney was killed December 20, 1935. My father, Patrick Gregory was 3 yrs. old, when his father had his accident. Thank you, Granddaughter & Great Granddaughter of John Gregory Tierney & Patrick William Tierney
