American River (South Fork)

DIY Guide to Fly Fishing the American River (South Fork)

The South Fork of the American River was the site of James Marshall’s famous discovery of gold on January 24, 1848, which sparked the California Gold Rush.

Nowadays, the River is more popular with white water rafters than prospectors, with the South Fork attracting around 80,000 visitors in 2011. 

The South Fork also provides excellent fishing opportunities as well, and anglers can find plenty of rainbow trout and brown trout weighing up to eight pounds. Still, it wouldn’t be much fun if it were easy.

Check out our guide so you can find out exactly what makes the trout of the South Fork of the American River tick.

Fly Fishing in the American River (South Fork)

The South Fork of the American River is a major tributary of the American River. The River rises at Nebelhorn, about ten miles south of Lake Tahoe. The River then flows west for 87 miles and empties into Folsom Lake. The North Fork of the American River also flows into this Lake, and together, the combined forks form the American River. The South Fork is fed by numerous tributaries, including Silver Creek, Rock Creek, Silver Fork American River, and Weber Creek. 

The South Fork boasts eight sections of boatable whitewater, which range from class II to class IV. In addition to whitewater rafting, outdoor adventurers are drawn to the River for the hiking, equestrian, and mountain biking trails, and for the breathtaking foliage. The fall colors are sure to dazzle you, but if you visit in the spring, you’ll be treated to a beautiful landscape of rolling hills blooming with wildflowers.

The River is stocked by the California Department of Fish and Game every year with rainbow trout. The South Fork also contains non game species including the Sacramento pikeminnow, the Sacramento sucker, the California roach, the Kokanee Salmon, and riffle sculpin, in addition to the brown and rainbow trout. The rainbows average in length from 10 to 12 inches. 

With so many outdoor activities to enjoy on the South Fork, it can be a great destination to visit with your family, whether there are other anglers in your ranks or not.

The upper reaches of the South Fork is relatively easy to access via Highway 50 (see map for access points). There are numerous pull-offs and picinic areas that provide access to the stream as it flows some 20 miles through Twin Bridges, Kyburz and Riverton.

Further downstream in the tailwater section below Chili Bar Reservoir, one of the best places to fly fish the South Fork is below Greenwood Creek.
