What is a Watershed?

From mountain top to mountain top, it's the land that water flows across or under on its way 

from streams and rivers to lakes and oceans. It's where you live, work, and play!

The headwaters of the Merced River are at the foot of the Clark Range in Yosemite National Park. The river flows for 145 miles (233 km) westward through a series of canyons, gorges, and the flat plains of California's Central Valley where it joins the San Joaquin River and flows to the Pacific Ocean through the Sacramento Delta and the San Francisco Bay.
