Step 1 : Introduction to the question "What was the Hoover Dam called under Franklin D. Roosevelt’s government?"
...Although it is universally known today as Hoover Dam, the massive structure on the Colorado River was officially called Boulder Dam during much of Franklin D. Roosevelt’s presidency. The dam was originally named after nearby Boulder Canyon, even though it was ultimately built in Black Canyon. In 1933, Roosevelt’s administration formally reverted to the name Boulder Dam, distancing the project from former President Herbert Hoover. It was not until 1947 that Congress officially restored the name Hoover Dam, which has remained ever since.
