The level serves as a connector between the four power plants and contains eight turbines, but only four are working. In some sections, water is flowing into the turbines. Touching the water streams will knock the Courier down, but cause no damage. There is no notable loot found here.
Hoover Dam lower level appears only in Fallout: New Vegas.
Behind the scenesEdit
The Hoover Dam lower level is based on the lower levels of the real world Hoover Dam, which includes similar walkways, tunnels, stairwells, and a resemblance overall in architecture and function.
