Beneath the shadows of Half Dome and El Capitan, in the heart of Yosemite Valley, lies the Merced River. It’s been known as a Wild and Scenic River since 1987. It’s a federal designation that aims to preserve river ecosystems and values. But after a major flood damaged much of the park’s infrastructure in 1997, environmental groups and park management clashed over plans for how best to restore the park in compliance with the law. Now, after 15 years marked by lawsuits and studies, a new management plan for the Merced River has been released.
