River Description

Overview:  
The South Fork Feather from the little Grass Valley Reservoir to the South Fork Diversion is a Lost Sierra Jewel that was discovered, or rediscovered, in 2004.  Even though this reach has flows every fall when the utility draws down Little Grass Valley Reservoir, little was known about the run due to its remote nature.  It takes roughly an hour to get to the put-in from either Oroville or Quincy, the two closest metropolises.  The foreboding views from the dam down into the first gorge likely scared off early would be paddlers from this reach.  What they did not know is that below this gorge, which is still a portage fest for most, is a classic run with many beautiful granite gorges and high quality whitewater. South Fork Water and Power, the utility that operates the Dam, has been more than willing to work with AW to schedule these flows so that they work for the paddling community.   This project has been going through FERC relicensing since 2003.  As part of that process South Fork Water and Power has agreed to schedule boatable releases from Little Grass Valley reservoir into the South Feather each fall.

Rapid Descriptions

Trash Can Falls (Class N/A, Mile 0.2)

Trash Can Falls

Trash Can Falls

This is a 20 to 30 foot falls in the middle of the top gorge.  Rusty Sage broke his boat after running the falls and landing in three feet of water. The bottom is said to be shallow all the way across the base of the falls.  None the less, some boaters are successfully running this drop.  If you are tempted to try it, you should thouroghly explore the landing first.

The portage is high on the right bank and requires catching a small eddy above the falls.



2nd Gorge (Class IV, Mile 1.0)

Second Gorge

After about one mile into the run, you will come to the second gorge.  This gorge contains a number of class IV ledge drops with several nice boofs.   Boat scouting should be reasonable for many paddlers.



Morneau's More Nose (Class IV, Mile 2.6)

More Nose

This is a rather innocuous looking drop with a very sticky hole at the bottom.  If you don't get your nose up, you won't punch the hole, hence the name. Shawn Morneau took a nasty beating here during the flow study.




Postage Due

Postage Due Entrance

This is one of the harder rapids on the run. The entrance is tricky, if you miss it you will get posted on the right rock at the top or the left wall at the bottom. The rapid finishes in a very pretty vertical walled gorge. You can do a short portage and seal launch on the right.

Live and Left Live (Class IV, Mile 3.0)

Live and Left Live

This rapid comes shortly after Postage Due. The rapid has a long lead-in and culminates in a riverwide 4 foot ledge that is best run on the left. Starting the rapid on the right gives you a nice charge to the left boof.

Left Over Postage (Class IV+, Mile 3.2)

Left Over Postage

This is the last hard rapid above Post Creek. The line is through the left slot to a six foot drop. You don't want the right side. The entrance can be a little tricky.

Post Creek (Class N/A, Mile 3.5)

The log at Post Creek

Post Creek enters on river right at approximately river mile 3.5. This spot is easy to recognize because of the large log that crosses the river just below the confluence. From this location a trail on river right leads up to FS Road 21N65 . The hike out requires about 30 minutes. This access location can be used for emergency egress or as an early takeout location. This take out also reduces the shuttle distance considerably.



Stump the Chumps (Class IV+, Mile 4.3)

Stump the Chumps

Shortly below Post Creek is a rapid named “Stump The Chumps: The top portion of this rapids is typically portaged due to the log in the main channel. A short portage on the right allows you to put in and run the class IV bottom portion of the rapid. River Mile 4.3

Roland's Nightmare

Roland's Nightmare

This rather innocuous looking rapid has a horrible cave sieve about half way down the rapid. To make matters worse, a significant amount of water flows into the cave. The rapid is not hard, just junkie and consequential. It is possible to portage on the left. River Mile 4.5

South Fork Falls

South Fork Feather

This narrow 25 foot falls is a mandatory portage. It is easy to have this one sneak up on you. The portage on the right is fairly easy but may require a little rope work with the boats. River Mile 5.1

Stein Stuffing (Class IV, Mile 5.8)
“Stein Stuffing” is the last significant rapid on the run. It requires a drop into a narrow slot; if you get deflected at all you can get broached sideways and likely swim, as Dave Steindorf did during the flow study.  The rapid can be easily portaged on the left. River mile5.75
