1997 Flood Recovery

The January 1997 flood was the largest experienced in Yosemite by this generation. The water volume of the Merced River reached 24,600 cubic feet per second, the highest flow in 80 years of recording. We know there have been three other floods of similar magnitude since 1937. The primary flood recovery objective was to restore facilities and operations in a way that would prevent destruction from future high water events. Secondly, the park wanted to make sure that flood recovery projects were compatible with the park's long range vision as defined in the 1980 General Management Plan.

Nevada and Vernal Falls

In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
