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.

 

Did You Know?

El Portal Boulder Bar

At the east end of El Portal, just west of Yosemite National Park’s boundary, changing river gradients, glacial history, and powerful floods have created a boulder bar with boulders much larger than typically found in such deposits. This is no ordinary boulder bar, however, for it contains massive boulders over a meter in diameter and weighing many tons.
