Wild and Scenic Rivers, like all rivers, are protected under the Clean Water Act, which requires states to establish water quality standards for waters within their jurisdiction. Every two years, states are required to report whether these standards are being met. In 2018, NPS compiled information from the most recent state assessments to identify the water quality status of all designated Wild and Scenic Rivers. Based on the information available at the time, NPS determined that roughly 44% of all Wild and Scenic River miles did not meet their water quality standards, with temperature, mercury, and metals being the most common causes of impairment.
