Due to hazardous currents and fast water velocities SCUBA diving in rivers is inherently dangerous. Inexperienced divers can easily find themselves in a life-threatening situation and even experienced divers can be caught off guard. Visibility is frequently poor, and without warning moving water can change direction and velocity. River bottoms contain a gauntlet of hazards including boulders, woody debris, litter, fishing line, pumps, weirs and other obstacles, presenting numerous opportunities for SCUBA gear to get snagged. Navigating river channels requires an understanding of fluid dynamics and should only be attempted by experienced, well-trained divers.
