MRP User Capacity Workshop

People biking along the Merced with someone floating in a raft on the river.

Biking and boating are just two of the many activities that visitors enjoy along the Merced River.

This workshop will outline how the National Park Service will meet Wild and Scenic River Act requirements to address user capacity, or the kinds and amounts of visitor use that can be accommodated in the Merced River corridor without negatively affecting river values. Foundational aspects of this process will be discussed along with engaging the public in first hand case examples. Relevant science and information will be brought to bear on this important topic to illustrate how user capacity will be addressed the planning effort.

Date: April 29, 2011
Time: 8 AM-4:30 PM
Location: Yosemite Lodge, Garden Terrace

Did You Know?

Yosemite Museum

When it opened to the public on May 29, 1926, the Yosemite Museum became the first museum building in the national park system, and its educational objectives served as a model for parks nationwide. It still functions much as it was originally intended, and currently exhibits items which mainly reflect the Native occupation of Yosemite Valley and its surroundings. When in the park, you can visit with one of three cultural demonstrators who primarily staff the Museum.
