Yesterday I mentioned Boulder Dam Hotel. Through the years there had been a bit of consternation as to what to call the dam. President Hoover, a trained engineer, strongly supported construction of a high concrete dam on the Colorado River to control its flows. In the 1800s and early 1900s the river would flood low-lying farmlands during the spring thaws and in late summer it decreased to a trickle. In 1928 President Hoover signed into law the Boulder Canyon Project Act, authorizing the construction of the dam. Democrats did not want the dam to be named after a Republican president, so for many years it was called Boulder Dam. It took an act of congress in 1947 to make it officially Hoover Dam. The dam was the greatest dam of its day. It has been featured as one of the Top Ten Public Projects of the Century, as well as a National Historic Civil Engineering Landmark. The cost of the project, $165 million, has been repaid to the Federal Treasury through the sale of Hoover Dam power sales. There are tours of the dam available, as well as a power plant tour.
