Yosemite Valley Flood - January 9, 2017 Morning Update

January 09, 2017 Posted by: Yosemite National Park Rangers

The Merced River peaked last night (January 8, 2017) at about 12.5 feet and is beginning to recede. The park is currently doing assessments and will reopen Yosemite Valley to the public once it's safe, and water and sewer systems can support increased demand.

El Portal Road (Hwy 140) has been closed at the park boundary due to the Yosemite Valley closure, however, a rockfall will keep that road completely blocked at least for today. Road crews and geologists are on scene.
