Lake Havasu is a reservoir located on the Colorado River in Arizona. It was formed in 1938 after the completion of the Parker Dam, which created a water storage capacity of 648,000 acre-feet. The lake is a popular spot for boating, fishing, and watersports, and it is home to many species of fish, including largemouth and striped bass. The hydrology of the lake is influenced by the snowpack in the mountains surrounding the Colorado River basin, as well as specific surface flow from tributaries such as the Bill Williams River. The lake also serves as a source of water for agricultural irrigation in the surrounding area. In addition to recreational and agricultural uses, Lake Havasu plays an important role in generating hydroelectric power and maintaining water levels downstream.
