River Description

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 classic run with many beautiful granite gorges and high quality whitewater. What is truly remarkable is that 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 releases on not only the Little Grass @

Paul MartzenDetails
> Because water was held in storage longer at Little Grass Valley this summer, releases
beginning August 17 and continuing through the end of September will be in the boatable range. The
planned schedule we have received from PG&E is as follows: > August 17 - begin ramping from
100 cfs to 250 cfs. Hold 250 cfs through September 1. > September 2 - ramp from 250 cfs to 300
cfs and hold at 300 cfs throughout September. This will take Little Grass Valley to its end of
September elevation of 5,022 feet, keeping the boat ramps at the reservoir in service until the end
of the month. > > The 300 cfs flow will probably continue into October as the fall drawdown
begins. I will let you know the updated flow schedule as we get closer to October. > > Can
you please add to the flow information posted that campgrounds at Little Grass Valley begin closing
after Labor Day, although many stay open through the middle of September. The Sly Creek Campground
will be closed on October 1. > > Thanks for posting the information. > > Kathy

Trash Can Falls

This is a 20 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 line 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)

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

The log at Post Creek

Photo of Large log across the river at Post Creek by Eric Petlock @ 300 cfs

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 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.

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

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
