Horseshoe Bend is a beautiful section of river that has seen relatively little boating use in the
past. It only has boatable flows during periods of spill; typically late Winter and Spring of an
average to high water year. Many years there is no spill at all and therefore no boatable flows.
Scheduled weekend recreation releases will happen in the future if certain fishery studies allow
it. In the meantime SCE started providing real time flow information in the summer of 2006, which
will allow boaters to use this reach whenever there is boatable flow.
The river character is classic pool drop, with long pools separating relatively short steep
drops. The streambed is a deep granite trench and many rapids are formed by large boulders. Most
rapids, even the small ones, have distinct horizon lines, which hide any view of the correct
route until you are just about entering the rapid or have in fact committed to the rapid. Low
cliffs or sculpted boulders form much of the shoreline, but all rapids are easily scouted from
shore. There are a few small beaches along the length and one large beach at about the halfway
point. It is a very pretty section of river.
Time required: One can enjoyably spend all day, but fast trips are also
feasible. A recent kayak trip at 2000 cfs with 3 boaters, doing 4 scouts, two portages, 1 swim,
and numerous rolls, took 2 hours and 15 minutes from put-in to take-out.
The Horseshoe Bend Trail is on river right. It comes close to the river in a
couple spots, but usually it is several hundred yards up on the hillside. Sometimes its path is
obvious but in many other areas it is faint. The downstream end of this trail starts where the
road to the powerhouse is gated. The upstream end starts from a level area a mile before you
reach Willow Creek. At the upstream end, there is a sign for the trail and a dirt road leading to
a power tower. Vegetation in the area is grasslands, brush, oaks and some Digger Pines.
Getting there: From Fresno, take Highway 168 (or highway 41 to Friant Rd to
Auberry rd), to Prather. Continue a couple miles then turn left onto Auberry road and go to the
town of Auberry. In town veer left at the school onto Powerhouse Rd. Drop down to Kerchoff
reservoir, cross the bridge and immediately turn left into a parking area which is the take-out.
Allow 1 hour and 10 minutes from Fresno. Continuing to the put-in, cross the highway to a small
but paved road. Drive 4.5 miles to Willow Creek below Reddinger dam.
From Madera take highway 145 to Friant, to Auberry rd, to Prather and Auberry, etc. See this
Google Map.
Put in: Is easiest at Willow Creek just downstream of the dam rather than at the
dam itself. Drive on a dirt road on the left side of the creek to where a huge pipe comes out of
the hill and crosses the creek. Duck under the pipe and follow the trail out to the main river.
Kayakers often just launch into the creek itself and fight through the trees on the way to the
river. Trees are thick in the creek just below the bridge and again very thick at the mouth. A
new trail is to be constructed someday, but the final plan has not been approved by the forest
service yet.
Sept 2008 trail status report to FERC.

You can launch near the dam, by carrying down a trail that leads to a gauging station. Launching
here allows you to run a big serious drop in a narrow gorge.
Take out any where at Kerchoff Reservoir. There is a large turnout on the
northwest side of the highway bridge and a decent take out underneath this bridge. It is a short
carry from the water up to the road, but rafters may wish to paddle across the reservoir to good
beaches with car access. The shuttle is about 4.5 miles on a paved one lane road. Allow 10 to 15
minutes driving time each way.

Toilets and primitive campsites are available at Smalley Cove on Kerchoff reservoir. Toilets are
also available at the boat ramp on Reddinger Reservoir, not far past the dam. There is an area
suitable for primitive camping at the put-in, but on the north side of the paved road, up a short
dirt road. There is a grocery store and several decent resteraunts in the nearby town of Auberry.
There are more stores and restaurants at the shopping mall in Prather, at the junction of Auberry
Rd. and Highway 168.
FERC Information: Reddinger Reservoir and Big Creek #4 powerhouse operate
under FERC license # 2017 reissued in December 2003.
Threats to the River:
The downstream area of the San Joaquin is presently under study for several potential large dam
and reservoir sites which could also affect this section of the river. See: Upper San Joaquin Basin Storage
Investigation Three sites are under serious investigation! One site is about one mile
upstream of the confluence with Finegold Creek and could have a maximum size of around 2.1
million ac/ft. Another site is downstream of Temperance flat and could be as big as 2.7 million
ac/ft. The last site is upstream of Squaw Leap about halfway through the Patterson Bend section.
This would only contain 1.4 million ac/ft. Despite their size maximum annual yield is only
200,000 ac/ft. All of these reservoirs will bury the Patterson Bend section and will also bury
some or all of the Horseshoe Bend section. Maps from the study showing the sizes of the proposed
reservoirs are linked below.
A speech by Gary Bobker of
the Bay Institute, gives some arguments against building new dams at these locations.

Chris Labounty comments:
Ran Horseshoe on Sunday (May 29, 2005) with a stomping flow (10,000 cfs). Reddinger had one door
full open, and a second maybe half way. Big water, confusing currents, and random whirlpools that
liked to try to turn you sideways or backwards right above holes. I can't recall a time I've ever
had to fight so hard to catch eddies, but I scouted about 5 times. Scouting Big Dog was near
impossible, as the big river right eddy appeared to be at a higher elevation than the current
going past. There was one enormous hole a little ways before Little Dog that took most of the
right half of the river. An exciting run to say the least, and I look forward to doing it again
at a downshifted flow. Interestingly, later in the afternoon, they had shut off the second door
of the damn and took things down a notch from the looks of the 1st rapid.

Flow in Horseshoe Bend is a combination of spill from Reddinger, now posted by Edison as San Joaquin River Above Willow Creek-Spill and the flow in Willow Creek. Willow Creek often contributes 100 cfs or so early in the season, but decreases to almost nothing by summertime. Willow can contributes huge amounts during some big winter rainstorms. Click on the "Show List" button and you can see flows for some other river reaches in the basin as well as reservoir elevations. See also Dreamflows for this flow and many other rivers.
There is a staff gauge behind a rock at the downstream side of the mouth of Willow Creek. The staff measures increments of 500 cfs, up to 5000 cfs.
Horseshoe Bend will occasionally have flows in the winter and early in the Spring from low elevation runoff. It will also receive any spill from Mammoth Pool, which usually occurs if the Snow pack in the basin is 100%. The probability increases as the snow pack rises above 100%. Depending on weather patterns, spill can sometimes occur with less snow pack.

Reddinger Dam diverts 3,600 cfs to the Big Creek #4 Powerhouse and controls flows into Horseshoe Bend. One gate open is typical. Two gates open means really big water and only the hard core will want to challenge themselves.
Some people do or have launched just downstream of the dam, but getting to the river requires descending steep and very exposed slabs that are very wet and very slimy. A better put in is to descend a trail from the access road gate to the gauging station,
This is the best put in option for paddling through the Reddinger Gorge. Look for the gated road leading down towards the base of the dam. A sign on the gates says, "Dam #7" The trail starts just outside the gate and leads straight down the hill. The trail is not in great condition but it is discernable. There are some stairs and ladders near the bottom.
After a mile of flatwater, small holes and ledges, cliffs develop, especially on the left. A group of large boulders block the channel. To scout, take out upstream on the right. At low flows the center slot is clean and the right side develops a route. At high flows the left side cleans up while the center develops into an ugly hole.

Boulders on river right block your view of this sharp right turn. Rocks in the middle of the entrance force boaters to go far left or down a steep drop on the right. The current pushes boats towards a big hole on the left. Paddle hard to get right. An equally large hole hides in the middle in the tail waves below. Scout or portage on river right. Good recovery pool below. A few boaters have had deep dark swims here after being separated from their gear. (mileage is an estimate)
The river turns right into the bottom of the horseshoe and heads west. The small Backbone Creek comes in on the left and forms the nicest sand bar on the section. Flat water allows one to enjoy the beautiful cliffs and scenery for the next .3 of a mile.
Big rocks obstruct the middle and left at the top of this steep drop. Enter on the far right, aiming diagonally left between a big hole on the right and the recirculation from the rocks blocking the middle top. Once past the right side hole, immediately cut back right to avoid a huge ledge hole on the left. Once past this left side hole, aim back to the far left to avoid the big hole in the bottom middle.

The river turns back north and immediately comes to "Little Dog", the lead in rapid to "Big Dog". An easy take-out for scouting is on river left. Scramble over some boulders to reach a sloping ledge that runs some distance along the river. You can scout all of Little Dog from this ledge and get a fair view of the entrance to Big Dog. With some rope work or strong climbing skill, you get onto the next ledge and probably scout Big Dog as well.
There are left, center and right routes through Little Dog. The center has more water at lower flows, but the side routes look easier at higher flows. A second drop just downstream is straightforward down the center. WARNING! Only about 40 yards of swift water separates the end of Little Dog, from the beginning of Big Dog. If someone swims out of Little dog there is a strong likelihood of also swimming Big Dog. At 3000 cfs the two rapids are starting to run together.

The most commonly run line is to take the narrow center chute and paddle hard towards the right. If you do not make the move properly, the current will push you back to the left towards an undercut boulder. Warning: In 2009 there is a long tree trunk stuck in the undercut. Stay Far Away! If you eddy out on the left above the rapid, you will be perfectly set up to enter the rapid at the right angle and with enough momentum.
When boaters exit Little Dog, they have a choice. Paddlers can head right to a small take-out, from where it is easy to scout, and easy to portage if so desired. At higher flows it can be very difficult to get into this eddy. Alternatively, boaters can paddle left towards several different eddies behind boulders. The lowest left side eddy situates one perfectly to run the center chute.
The river enters a large round pool with a very narrow exit down a single steep drop. There tends to be strong recirculation at the base. Boats have to punch one side or the other of the hole, but the exact best line varies with flow. Scouting from river left is easiest. The right wall below the drop is very undercut and there is a strong eddy current going under it. If swimmers or equipment get pushed into this eddy, it can be awkward to reach them.
Past this drop, moderate rapids, weird upwelling and beautiful scenery continue until just above the powerhouse.

cfs. I ran it with Dan and Evan, and I have to say they did a great job showing me the lines. I
must also say I was quite nervous. I was happy to discover that all the holes that I encountered,
or watched those guys try to punch through and then get flipped, were all washing out. There were a
few really large and nasty holes, but they were easy to see and avoid as you paddled down the
rapids. The bottoms of most of the rapids were made up of these crazy lateral waves that were
bouncing off the sides of the canyon, along with some very strong boils. This all helped add to my
excitement and nervousness. Once I got over my fears, I was able to enjoy this incredibly scenic
river that included some beautiful granite gorge walls. We also saw three large owls near the
put-in, a first for me, after living in the area for seven years. I uploaded pictures and videos
for your enjoyment, and I hope it encourages you all to take a trip down this section of river.
