Dive-site story
Situated along the Black Canyon section of the Colorado River south of Hoover Dam, Willow Beach offers freshwater diving shaped by cold hypolimnetic river releases. The riverbed features rocky outcroppings, submerged trees, canyon walls, and fish hatchery infrastructure. Divers encounter stocked fish alongside resident river species against sheer canyon walls extending below the surface.
