Wilderness beauty and big drops are the promises when rafting the Middle Fork of California’s American River. The whitewater rafting run that starts just below the Oxbow Powerhouse and includes rapids like the Last Chance, Tunnel Chute, Kanaka, Chunder, Ruck-A-Chucky Falls and heaps more. These rapids demand skilled guides, good paddling technique and world class equipment.

The Middle Fork American River is rated a Class III-IV river and runs through Tahoe National Forest. In addition to the bigger rapids there are also numerous Class II rapids scattered throughout the deep canyon. Large pools follow most of the big rapids allowing you plenty of time to set up for the next rapid or to get regrouped after that unexpected, out-of-boat experience or upside down raft. The rapids on the Middle Fork are created by large boulders and natural slides with the exception of Tunnel Chute.

One of the most notable rapids on the Middle Fork American is the world class Tunnel Chute. This is a man-made rapid created during the mining days of the late 1800’s. Black powder was used to blast through the cliff wall, diverting the water out of the oxbow so it could then be mined for gold. There are many sharp rocks hidden in the chute…so think twice before you decide to fall out or swim it.

The Ruck-A-Chucky Rapid is an unrunnable Class VI 30 foot waterfall. You can portage this rapid via right side trail. The portage itself is about 100 yards long and takes about 30 minutes depending the number of boats you have. This is a great spot to watch how the various guides and rafting companies negotiate the portage. Skill, experience and quite a bit of luck is involved.

Mile 0.1
Good Morning (Class III) – Aptly named rapid is going to make sure you’re awake and paying attention to your guide.

Mile 0.2

Last Chance (Class IV) – This is a near vertical drop that can easily flip or surf a raft. Just below it Tunnel Chute Rapid awaits so when your guide asks you to paddle – make sure you listen.

Mile 1.5
Tunnel Chute (Class IV)
– This rapid was created by some industrious miners in the 1890’s that wanted easy access to the gold rich river bed at Horseshoe Bar. The blasted a tunnel through the narrow part of the horseshoe and then blasted a chute in the bedrock to divert the river to their new tunnel. The sharp rock walls in the chute make this a rapid that you don’t want to swim. This is an amazing rapid and interesting place that all serious California rafters should visit at least once.

Mile 13.3
Ruck-A-Chucky Falls (Class VI – portage)
– This rapid used to be un-runnable, but became merely V+ after high water re-arranged big boulders in winter of 1992. Before this rapid became less hazardous, several kayakers had tried to run it; all died or became partially paralyzed.
There is an easy portage path and viewing platform on the right. Some kayakers say that the portage is easier, though exposed, on the left side, but that was before the portage path was built. Some commercial outfitters ghost-boat their rafts over the falls while some guides are comfortable running it. Guests always walk around.
