Lake Las Vegas in Henderson, Nevada, refers to a 320-acre artificial lake and the 3,592-acre developed area around the lake. The area is sometimes referred to as the Lake Las Vegas Resort. It is being developed by 5 companies including Lake at Las Vegas Joint Venture LLC. The area includes three resorts including the Aston MonteLago Village Resort, the Westin Lake Las Vegas Resort, and the Hilton Lake Las Vegas.

The dam that creates the lake is “an earthen structure 18 stories high, 4,800 ft in length and 716 ft wide at its base. It contains roughly the same amount of dirt as Hoover Dam does concrete,” and was completed in 1991. The Las Vegas Wash passes under the lake and dam in pipes that require maintenance every 10 years. The property was acquired by Transcontinental Properties in 1990. In 1995, Henry Gluck, the former chairman and chief executive officer of Caesars World, became the co-Chairman of Transcontinental Properties. With Sid Bass and Lee Bass, two billionaires from Fort Worth, Texas, he developed the new community. The project cost US $5 billion.
