The Middle Fork is 62 miles (100 km) long.
It originates a mere 1.7-mile (2.7 km) from the source of the North Fork on the south face of Granite Chief, between the summit and Emigrant Pass.
It is characterized by somewhat broader steep canyons interspersed with reservoirs, waterfalls, and quiet riparian areas.
 The Middle Fork is used extensively for both motorized and non-motorized recreation, including fishing, white water adventuring, bicycling (mountain and road), horseback riding, trail running and hiking.
 It contains areas used for hydroelectric generation, mining, and agricultural timber cultivation and harvesting.

The Middle Fork features part of the Auburn State Recreation Area.
The Western States Trail hosts multiple annual endurance events, including the Tevis Cup equestrian trail ride, and the world-famous Western States 100- Mile Trail Run, both beginning at Squaw Valley and leading to Auburn via remote wilderness trails.
