LAKE MEAD NATIONAL RECREATION AREA, AZ - MAY 12: A tall bleached 'bathtub ring' is visible behind the Hoover Dam on May 12, 2015 in Lake Mead National Recreation Area, Arizona. As severe drought grips parts of the Western United States, Lake Mead, which was once the largest reservoir in the nation, has seen its surface elevation drop below 1,080 feet above sea level, its lowest level since the construction of the Hoover Dam in the 1930s.

LAS VEGAS - Officials say there will be fewer Hoover Dam tours starting next month as work begins on renovations to the visitor center and guest elevators at the iconic structure.
The U.S. Bureau of Reclamation, which operates the dam, announced Tuesday that the construction will begin Oct. 1 and continue for about four months.
The Las Vegas Review-Journal reports the primary visitor center exhibit and other attractions will remain open during the work, but only a limited power plant tour will be offered during that period.
Leonard C. Schilling, area manager of the Lower Colorado Dams Office, said in a written statement that the tickets for the tour will be sold on a first-come, first-serve basis.
Online ticket sales will be suspended during this time period.
