The two names are referring to the same dam, so one is not older than the other.
Hoover Dam was named for Herbert Hoover, the 31st US President.
According to the Bureau of Land Management website, the name of the dam built as part of the Boulder Canyon project was always "Hoover Dam". That was stated by the Secretary of the Interior on Sept 30, 1930 when construction started and the name was made official by an Act of Congress on February 14, 1931. The name "Hoover Dam" was never officially changed. It was political pettiness that perpetuated the names "Boulder Canyon Dam" and "Boulder Dam".
In 1947, resolutions were passed in the House and the Senate and signed by President Truman to restore the original name.
