Wanderlust World Wanderlust World Lake Havasu, a picturesque freshwater reservoir straddling the Arizona–California border, is a popular destination for boating, fishing, and water sports. One question visitors sometimes ask is whether sharks inhabit the lake. The answer is a definitive no.
Sharks are fundamentally marine creatures; their physiology is adapted to saltwater environments. Lake Havasu is fed by the Colorado River and consists entirely of freshwater. Without the salinity sharks require for osmoregulation, they cannot survive there.
Instead of sharks, the lake supports a variety of freshwater fish such as bass, catfish, crappie, and bluegill. Its clear waters and desert surroundings make it a unique recreational spot, but you’ll never need to worry about a shark encounter.
