River Description


The Electra Run is a wonderful class 2 section suitable for beginning white water boaters.   It has dependable summer flows and nice scenery.  The Electra Powerhouse usually runs for some portion of each day.  Maximum flow from the powerhouse is about 800 cfs.  Spring flows when upstream dams spill can be much higher.  The river is fairly narrow with lots of swiftwater, riffles and eddies.  There are only a few rapids harder than class 1, so it is popular with beginner boaters as well as floaters and swimmers.  There are many turnouts and swimming areas along the run.

Getting there:  This section of the Mokelumne crosses Highway 49 between the towns of Jackson and Mokelume Hill. Driving time is about an hour and ten minutes to an hour and a half from Stockton, Sacramento or Modesto.  There are a number of alternate routes from each direction so click on the directions tab and calculate the route from your zip code.

Put in:  From Highway 49 drive 3 miles up Electra Powerhouse Rd.  This road is paved, but narrow, old and heavily repaired.  The put in area is well marked and there is a large beach for launching boats and swimming.  The road continues anouther half mile to the powerhouse, but there is an old dam on the river in between.

Take out:  There are two common options.  At highway 49 there is a large parking area on river left, called Big Bar.  This take out makes for a short shuttle. and still gets most of the whitewater rapids.  The new option is to take out at Middle Bar which is two miles downstream.  From Electra Powerhouse Rd & Highway 49 drive north towards Jackson 2.2 miles.  Turn left onto Middle Bar Rd and drive 3 miles to the take out parking area.  Middle Bar Rd is paved but narrow, old and heavily repaired. Alot 10 or 12 minutes to go the 3 miles.

The opening of the Middle Bar Bridge take-out now makes the run from Electra Afterbay Dam to the bridge about 5 miles. This is a great Class-II reach with nearly dependable water in the summer due to peaking power generation. Getting this formerly restricted area open to boaters was a key focus for American Whitewater in the relicensing of the upstream PG&E Mokelumne hydropower project.

 
Annual Mokelumne River Races:
Each September since 1978, the Sierra Club Loma Prieta Paddlers has hosted slalom and downriver races on the Mokelumne.    The official race website is at:  mokeraces.com

Rapid Descriptions

Put-in

Class - I Mile - 0

This great beach is located just below the parking lot at the put in.  There is a large pool for practicing and warming up.  You can also paddle upstream quite a ways.

Boulder Bar

Class - II Mile - 0.36

Fun bumpy water

Goal Post

Class - II Mile - 0.91

A long moderate rapid bends to the right, then back to the left.  This appears to be the site of the annual Moke river races, slalom course.

S-Turn

Class - II+ Mile - 2.6

The river drops over a gravel bar, moves left, passes some large rocks (or holes at higher flows), then turns again to the right .

49 Bridge / Big Bar Parking

Class - N/A Mile - 2.9
Rapid Thumbnail Missing

There is a large parking area on river left just below the Highway 49 bridge.  There are two entrances, one on each side of 49, so you turn right no matter which way you are coming from. 

On the water, float under the bridge and look for take out options on the left.  There is a big beach just below a small rapid. 

Looks like there are trails down to Devil's Toilet Bowl rapid from here.  You could scout that rapid or even carry back to this parking area after running that rapid.

Devil's Toilet Bowl

Class - III Mile - 3.1

This is the biggest rapid on the run. It's II+ or III- depending on the flow.

 

Rapid

Class - I Mile - 3.61
Rapid Thumbnail Missing

There are several small rapids along this section down to Middle Bar.

Middle Bar Take Out

Class - N/A Mile - 5.5

Take out on river right about 100 yards before the bridge.  A trail leads up past some picnic tables, and across the road to a parking area with two pit toilets. 

At the bridge itself, there are chain link fences and no trespassing signs.

The Electra run has dependable year round outflows from the PG&E Electra powerhouse which is just upstream.   Powerhouse flows are generally around 700 cfs.

Mokelumne River - 2017 Recreational Flows (CA)

2017-04-27 21:11:00-04
Theresa Simsiman

American Whitewater has been helping to implement negotiated recreational flows on the Mokelumne River for over 15 years. This year’s record water year poses some challenges on roads across California that were washed out due to winter storms. It is no different on the Mokelumne watershed. However, we still have opportunities to paddle!

2016 Summer Releases Mokelumne River - Electra to Middle Bar (CA)

2016-06-12 00:36:00-04
Theresa Simsiman

In the settlement negotiations that preceded the 2001 license order for the FERC Mokelumne River Project #137, American Whitewater was satisfied with the recreational flows required for the Electra to Middle Bar reach. However, over the past few years dependable boatable flows on the Mokelumne Electra run have all but disappeared.

Expanding Pardee Reservoir Still on the Table - Speak up for the Moke (CA)!

2011-07-22 00:00:00-04
Megan Hooker

The EBMUD is seeking comments on their revised 2040 Water Plan, which continues to seek to drown part of the Mokelumne River in California.  The Electra Run and Middle Bar Reach are not only an important resource for whitewater and other river based recreation, but are also hold cultural significance.  EBMUD needs to hear from all who love the Moke that expanding Pardee Reservoir is still a bad idea.  Submit your comments by Friday, July 29th.

On October 13, 2009 East Bay Municipal Utility District's (EMUD) Board Members voted to approve their Waste Supply Management Program (WSMP) 2040. Proposals to enlarge Pardee Reservoir, included in this plan, remain a threat to our whitewater interests on the Molkelumne River.

Mokelumne River is a California State Wild and Scenic River!

2018-09-06 11:23:00-04
Evan Stafford

Decades of home grown advocacy, including heavy lifting done by our colleagues at Foothill Conservancy and Friends of the River has finally resulted in the permanent protection of thirty-seven miles of the North Fork and main stem of the Mokelumne River. Like the Federal Act upon which it was modeled, the California Wild and Scenic Rivers Act affords, “certain rivers which possess extraordinary scenic, recreational, fishery, or wildlife values shall be preserved in their free-flowing state, together with their immediate environments for the benefit and enjoyment of the people of the state.”
