Hetch Hetchy Reservoir in Yosemite National Park, California, is currently closed to paddling and other boating activities. Despite its scenic location surrounded by towering cliffs and waterfalls, the National Park Service does not allow non-motorized vessels on the reservoir. This restriction is unique within Yosemite, as human-powered boats are permitted on other water bodies in the park.

The reservoir offers outstanding vistas, including views of Tueeulala and Wapama Falls that are not visible from hiking trails. If paddling were allowed, it would provide access for picnickers to reach Rancheria Falls, climbers to approach Hetch Hetchy Dome, and anglers to fish streams feeding the reservoir.

Restore Hetch Hetchy, an advocacy group, is working to encourage the National Park Service to allow kayaking and canoeing on the reservoir. They argue there is a compelling rationale that non-motorized vessels should be permitted, citing the intentions of Congress when passing the Raker Act. However, as of 2024, paddling remains prohibited on Hetch Hetchy Reservoir.

Visitors interested in paddling experiences within Yosemite National Park should consider alternative options like the Merced River in Yosemite Valley or Tenaya Lake in the high country. These areas offer sanctioned paddling opportunities with stunning Sierra Nevada scenery.
