User Capacity Management Program for the Merced Wild and Scenic River Corridor

These documents describe the management tools employed by the National Park Service to address visitor use throughout Yosemite National Park. This program has expanded in recent years from monitoring efforts in the Merced River Corridor to further reaching visitor use monitoring parkwide. The documents introduce guiding legislation, management systems that have been in place for decades, and the latest park efforts in establishing standards, indicators, and monitoring programs for visitor experience and resource protection.

Did You Know?
Yosemite Falls is fed mostly by snowmelt. Peak flow usually happens in late May, but by August, Yosemite Falls is often dry. It begins flowing again a few months later, after winter snows arrive.
