Overview of the Merced River

The journey of the Merced Wild and Scenic River is nothing short of spectacular. From the Sierra Nevada crest in a World Heritage Site crown jewel national park, to foothill meadows and river-carved canyons, discover the Merced and its South Fork a one-of-a-kind river.


On November 2, 1987, the Merced River was designated by Congress as a Wild and Scenic River, becoming part of Wild and Scenic Rivers System. A free-flowing river, the Merced and its tributaries possess pristine water quality, and rare, unique values that set it apart from all other rivers in the nation. The Merced River flows from its source (including Red Peak Fork, Merced Peak Fork, Triple Divide Peak Fork, and Lyell Fork) in Yosemite National Park, to the normal maximum operating pool (water surface level) of Lake McClure (elevation 867 feet mean sea level). The South Fork - the Merced River’s largest tributary - flows from its source in Yosemite National Park and the community of Wawona, to the confluence with the main stem.
