About Lake Havasu

Lake Havasu is a reservoir on the Colorado River in western Arizona, United States, created by Parker Dam and completed in 1938. It forms a long, narrow lake used extensively for boating, fishing and water recreation.

The eastern shore is home to Lake Havasu City, a purpose-built community known for water-based tourism and seasonal events. The lake and city attract visitors for boating, houseboats and waterfront recreation throughout the year.

A notable modern landmark associated with the community is the relocated London Bridge, which was dismantled in London and reassembled in Lake Havasu City in 1968. The reservoir also plays a role in regional water storage and management on the Colorado River.

The lake straddles the border area between Arizona and California; Lake Havasu City sits on the lake’s eastern shore in Arizona.

  • Creation date: Formed by Parker Dam in 1938, creating a major recreational reservoir on the lower Colorado River.
