Pit River (CA)

The Pit River is the largest river in northeastern California; its watershed is 4,324 square miles. The Pit flows in a southwesterly direction through valleys and basalt canyons before being inundated by Lake Shasta, where the confluence with its main tributary, the McCloud River and the Pit’s confluence with [...]Read More


River Description

This section of the Pit River is in a deep canyon through a volcanic plateau. Upstream of this section, on top of the Modoc Plateau, the Pit River meanders through pastoral countryside. At Fall River Mills, the Pit is joined by Fall River and begins cutting a canyon. Over seven miles, the river cuts to the bottom of the plateau and exits onto another lower basin. Like the adjacent Upper Klamath, the Pit River has a basalt riverbed which is generally uncommon in California.

The Pit 1 reach is a great class IV+ run that has fall weekend releases, thanks to American Whitewater. Flows are normally diverted around this section for hydropower but during scheduled weekends in the fall, flows are restored to the river providing a great recreational resource for the community. This section also has boatable flows during periods of powerhouse maintenance (usually scheduled around the same time as the fall boating flows) and in winter or early spring when there's more water in the river than PG&E can divert for hydropower generation. American Whitewater also secured real-time flow information for this run to benefit the boating community. Note that release flows have a 7-8hr travel time to the gauge so it may not accurately reflect the current reach conditions or may read as low during a recreational release.

The put-in is on the river left across the bridge from Fall River Mills at a river access facility built and operated by PG&E. Use of the river access is free and there is a paved parking area, vault toilet, and short trail to the river.

The first 1.8 miles on the water is a scenic, mosty flatwater warm-up before the whitewater begins. It takes about 20 minutes from the put-in to reach the first bona fide whitewater rapids. The old access closer to the start of the whitewater crossed private property and access here is no longer allowed: please do not trespass here.

PG&E River Access

Distance: 0 mi
PG&E River Access

PG&E has built a parking area with pit toilets on the hill above the river just dowstream of the Fall River confluence.  Parking spots are limited and there is no room for trailers.

A nice trail leads down to a low weir across the river. It is easy to launch above this weir into a flat pond area. There is gap in the weir on river right that should have a reasonable route. It could have obstacles in it, so always double check. The weir itself is very low and could be scraped over at various points, but trees and bushes grow all across the river below the weir on shallow ledges. Most of the width is obstructed.

The maintained trail ends at the weir but a rough use trail wanders over low rocks and through trees to access the open flat water below the trees.

Kayakers could easily carry past the weir on the trail, but groups carrying rafts would have a more difficult time.

Start of whitewater

Start of whitewater

This marks the end of the flatwater and the beginning of the whitewater. Access to the river here is not permitted across the privately owned land (Big Eddy Estates); please do not trespass.

Small Ledge

Class: IIIDistance: 2.13 mi
Rapid
Small Ledge

Small boulders form a river wide ledge. There are multiple lines over it, but it might be sticky in spots.  There are good eddies above it. A cheat chute on far left, to the left of a tree offers a more gradual descent.

Typewriter

Class: III+Distance: 2.2 mi
Rapid
Typewriter

This is a two part rapid with a tricky end.  There is a fairly steep but open lead in to a big eddy on the right.  The lower drop must be run on the far left because of a sticky ledge guarding the center and right. However a strong curling diagonal wave guards the left and must be punched. This diagonal often typewriters boats all the way across into the rocks on river right where a strong eddy can feed them back into the ledge hole. It caused more problems at 1100 cfs than at 800 cfs.

Unhappy Ending

Class: IV+Distance: 2.78 mi
Rapid
Unhappy Ending

A long straight, but congested rapid with multiple slalom routes ends with even greater congestion. A line of boulders create holes and boof opportunities across the entire width except for the far right. An upstream line of boulders guards the right side and prevents a straight approach.

A common line is to enter center or left, then when it opens up head down the center. At 800 cfs many people could cut to the right at the bottom between the two lines of boulders to run the clean exit. At 1100 cfs the right cut is much harder and most people charged through the bottom boulders where ever they ended up.

Spring

Distance: 2.85 mi
Other
Spring

A small spring runs into the river on the left near the end of a large pool. Boaters can paddle up to it to drink and refill water bottles.

Pit River Falls: Right Side Slide

Class: IVDistance: 4.59 mi
Portage
Hazard
Waterfall / Large Drop
Pit River Falls: Right Side Slide

The river spreads out and green islands hide the top of the falls. There is a scouting and portage route at water level on the right edge of the falls. A steep clean slide is often run on the right side, as well.

On the left side of the falls there is also a scouting and portaging route.

Pit Falls: Left Side - Fish Ladder

Class: IV+Distance: 4.6 mi
Portage
Hazard
Waterfall / Large Drop
Pit Falls: Left Side - Fish Ladder

The so called Fish Ladder, breaks the descent into several smaller waterfalls in a small channel. The landings are tricky on several of the drops. The very bottom drops are portaged if the flow is not high enough. The entrance to the left side channel is separated from the main falls by a large island. The channel curves around the island and ends up back near the base of the main falls.

It is also possible to portage or scout the falls across the island.

Pit Falls: Center Chute

Pit Falls: Center Chute

This center chute is often run but not successfully at all levels. At 800 cfs one day several boaters ran it. At 1100 cfs the next day only two boaters attempted it, as both got pummeled in the base and swam. Thankfully they were quickly ejected towards shore when they did swim.

Pitbull

Class: IIIDistance: 5.1 mi (approx.)
Rapid
Pitbull

A nearly river wide horizon line waits at the end of a fast class 3 section. You can boof the rock in the middle but it all goes.

Powerhouse Outlet Channel

Distance: 6.71 mi
Other
Powerhouse Outlet Channel

The outlet channel comes in on river right. It is a straight channel and so provides an interesting view of the powerhouse and the penstocks above it. During release weekends there won't generally be any flow out the channel.

Campground Rapid

Class: IIDistance: 7.02 mi
Rapid
Campground Rapid

This rapid has a semi-clean route down a rocky bar on the left side and then it curves to the left down a second level. Unfortunately the take out boat ramp is hidden in a side channel lagoon back to the right. You can't run the clean part of the rapid unless you want to continue downstream.

To get to the take out, kayakers scrape and bash down the right edge of the rapid into calm water. They can then paddle upstream into the lagoon. Rafts can try the same but will hang up even more and will likely end up walking the raft through the shallows.

More commonly, rafters enter a tiny side channel that feeds the lagoon and drag their rafts a shorter but still awkward distance into the lagoon.

Well attended release. Great flow level. Be advised that while PG&E may start the release flow on Friday, as they did on this weekend, the required release days are only Saturday and Sunday.

Rafters be aware: There is a ripper rock just under the surface mid-stream just after Unhappy Ending.

We put a 7' gash in a SOTAR in the flat-water runout from the rapid last year.  If I recall, it was only about 50' after the end of the last move right in mid-current at average flow. We have no idea what did it, but it was immediate. I had the boat sideways as we were looking back at the rapid a slice sound and a hiss right across the side of the left-side tube.

I'll be staying further left or right after the last move in that aptly-named drop.

Beautiful fall days at Pit Falls.

Access built by PG&E without input from American Whitewater. Limited parking, long hike to the river, no trailer turn around are just a few of the issues.

Long rapid - the main feature is Egg Beater- a set of egg shaped rocks forming some big hydraulics. No great line here, read it and eat it.
