South Fork American River

Chili Bar and Gorge Runs The South Fork American, California's most popular whitewater river, provides 100,000 people a year with a thrilling ride through the heart of Gold Rush Country. Below the Chili Bar put-in the South Fork drops quickly through a remote, steep-walled canyon cut into metamorphic volcanic rock. Five miles farther, where the canyon opens up into the gentle Coloma Valley, Troublemaker Rapid provides the climax of the Chili Bar stretch. Civilization is close at hand for the next four easy miles between Coloma and Lotus. Then the river heads into back country again, winding through foothills and finally plunging into the exhilarating, nearly continuous rapids of the South Fork Gorge before stilling in Folsom Reservoir.

Dam-controlled flows often make the South Fork runnable year round. On summer weekends the river is very crowded. But weekday boaters enjoy the scenery and the bouncy but forgiving rapids in relative solitude. The Chili Bar and Gorge runs are considerably more difficult at flows over 3,000 cfs, but they are tough enough even at low and moderate levels to get the inexperienced into trouble. Beginners and novices should stick to the Class II stretch from Coloma to Lotus, or the Class I - II run on the Lower American below Folsom Reservoir.

The South Fork runs are on a small remnant of river bounded by Chili Bar Dam upstream and Folsom Reservoir downstream. Even so, additional dams have been proposed, including one at the site of Troublemaker Rapid. After negotiations involving river runners, landowners, and El Dorado County, in 1982 the California Legislature passed a bill to delay new dam proposals for at least ten years if a series of dam and diversion projects were approved for the upper South Fork above Kyburz. As of 1992 none of these projects had been built, and it was uncertain whether dam proposals on the South Fork would be renewed. The river is also threatened by an El Dorado County proposal to divert 20,000 acre-feet from the upper South Fork. Such a diversion would severely restrict instream flows and hamper boating. (For updated information contact Friends of the River; see appendix for address.)

Another problem is the extensive private property along much of the river below Chili Bar -- an important factor in El Dorado County's abortive attempt to prohibit whitewater sport on the South Fork in the early eighties. After the courts ruled that the public had the right to run the river, El Dorado County took over the task of regulating boating. The county now patrols the river, requires private river runners to register at put-ins, and asks all boaters to observe a "quiet zone" between miles 4.4 and 11.5. Use fees from commercial rafting outfitters provide the county with a tidy sum.

With so much private land, the South Fork faces a grave threat from the tremendous growth of greater Sacramento. New houses are appearing in previously undeveloped sections of the canyon. Leading the effort to protect the river from uncontrolled growth is the American River Land Trust, which has purchased sensitive parcels in the South Fork Gorge and is working to buy more riverside land in the Chili Bar stretch. The Trust's office and Nature Center in Coloma is well worth a visit (see Side Excursions).

Upstream Runs The South Fork offers some boating -- primarily for experts only -- above Chili Bar Reservoir. U.S. Highway 50 follows much of the upper river, offering easy access but detracting from the solitude. The most common run on the upper river is 7 miles of Class IV - V water from Kyburz to Riverton. Just above Riverton the South Fork cuts a steep chute through sharp rocks where a landslide bocked the highway and temporarily plugged the river in 1983. The run can be extended another 3.5 miles by continuing past Riverton to the Peavine Ridge Road bridge. Below Peavine the South Fork roars down an extremely steep Class VI gorge that drops more than 200 ft./mi. in places. This stretch is known as the Golden Gate Run because boating it is nearly as suicidal as jumping off the Golden Gate Bridge. (For more information on the upper river, refer to the guide books by Cassady and Calhoun or Holbek and Stanley listed earlier.)
