In 1987 the U.S. Congress designated the Merced a Wild and Scenic River to preserve its free-flowing condition and to protect and enhance the unique values that made it worthy of special protection under the Wild and Scenic Rivers Act. Both the Merced River above, through, and below Yosemite Valley, and the South Fork of the Merced above, through, and below Wawona have this special status.
In accordance with the law, the National Park Service (NPS) is preparing the Merced Wild and Scenic River Comprehensive Management Plan and Environmental Impact Statement (Merced River Plan/EIS) for the 81 miles of the river within Yosemite National Park. When completed, the plan will guide future management of activities in the river corridor, including site-specific actions needed to protect the river in Yosemite Valley, El Portal, and Wawona.
