Lake Havasu City was established in 1963 by Robert P. McCulloch (of McCulloch chainsaws) as a planned community. McCulloch had purchased 3,500 acres (14 kmē) of property on the east side of Lake Havasu along Pittsburg Point, the peninsula that eventually would be transformed into "the island". The city was incorporated in 1978. The present city grew around an old mining town established in the early 20th century.

Lake Havasu City is a city in Mohave County, Arizona, United States. According to 2006 Census Bureau estimates, the population of the town is 56,355. The community first started as an Army Air Corps rest camp during World War II on the shores of Lake Havasu.

The lake was formed in 1938 by Parker Dam on the Colorado River. One cannot reach the Grand Canyon from Lake Havasu due to the dams: Davis Dam (creating Lake Mohave), Hoover Dam (creating Lake Mead), and Parker Dam.
