Low-head dams likely wouldn't catch the attention of a person floating down a river on a paddle board or inner tube. The unassuming structures can have drops as low as 1 foot, appearing as little more than a smooth bump in otherwise calm waters. But the continuous motion of water over the top of the dam creates a dangerous vortex at its base. As recently reported in the Register Guard, the churn can trap swimmers, kayakers and others recreating in the water, earning them the nickname “drowning machines.”
