How Cofferdams Helped Build the Hoover Dam
Located on the cusp of Clark County in Nevada and Mohave County in Arizona in the United States, is an architectural wonder known as Hoover Dam. The name was originally Boulder Dam, but was interchangeable, depending upon the political standings of the speaker, but was confirmed by President Harry S. Truman in 1947. The purpose of this marvel is to provide flood control, water storage and regulation, power, and it also serves as recreational landmark. Countless numbers of tourist traverse across the United States every year just to stand witness to its beauty and strength.
The construction of the site began in 1931 and complete d by 1936. It measures over 726 feet high and 1,244 feet in length, 660 feet wide at the base, and holds a whopping 28.9 million acre-feet (approximately 325,000 gallons per acre feet) of water.
