EAST FORK Lewis River is a free-flowing stream in SW Washington near Vancouver. EAST FORK begins up in Gifford Pinchot National Forest and travels down through Clark County connecting with the main Lewis River near Woodland, Washington. The Lewis River is part of the Columbia River System and is home TO steelhead, coho, chum, and chinook salmon. The Main Lewis River, sometimes called North FORK Lewis River, starts in the Cascade Mountains, 75 miles northeast of Portland, Oregon. It flows through Gifford Pinchot National Forest passing south of Mount. Helens. It enters the Columbia River approximately 15 miles north of Vancouver, Washington. EAST FORK Lewis River, one of the last free-flowing rivers in SW Washington, is in serious trouble! Over the last 150 years, the River has been stripped of its old growth timber, burnt over by Yacolt fires, and severely degraded by gravel mining. Its wild fish have been over harvested almost TO extinction. Development crowds its banks and riparian areas. EAST Forks wild salmon and steelhead suffer from high water temperatures, lack of cool ground water, recharge pools, and cover. Its spawning redds have been destroyed by silt. NOW is time TO say ENOUGH! NOW is time for us TO WORK TOGETHER TO BRING EAST FORK BACK FROM BRINK!

Course

The Lewis River rises in the Cascades in northeastern Skamania County, high on the west flank of Mount Adams, approximately 75 miles northeast of Portland, Oregon. It flows generally southwest through Gifford Pinchot National Forest, across central Skamania County, passing South of Mount. Helens. It form boundary, along the Dark Divide on its north side, between Cowlitz County, to the North, and Clark County, to the South. Towns along the river include Cougar, Ariel, and Woodland. In its lower 10 miles, it turns sharply South, then west, and enters Columbia from East, opposite. Helens, Oregon, approximately 15 miles North of Vancouver, Washington. The mouth of the Lewis River is at Columbia River mile 87 or River kilometer 140. Near the confluence with the Columbia River, Lewis River is joined by the East Fork Lewis River. The Main Lewis River, sometimes called North Fork Lewis River, forms the boundary between Clark and Cowlitz counties, while East Fork divides Clark County in half. East Fork flows westward from headwaters on the western flanks of Lookout Mountain in Skamania County. Parks along East Fork include Moulton Falls, Lucia Falls, Lewisville, and Paradise Point. The variant name of East Fork is South Fork Lewis River.

Hike Description

Update post 7 / 31 / 2020 by Gifford Pinchot National Forest: Lower Falls Day Use Area is closed to prevent spread of COVID-19 due to overcrowding issues during Summer of 2020. Please visit Gifford Pinchot NF website for updates. Lower Falls Campground is open by reservations only. It is extremely popular, make reservations well in advance. This is one of the premier waterfall hikes in our area. From Lower Lewis River fall Trailhead make your way down any of Use paths to views of Lower Falls. The trail on the edge of Bluff is the Lewis River Trail. Walk to the right as far as you like for different views of the waterfall. There are dozens of different segments and literally hundreds of vastly different photographic possibilities. There are a couple of informal side paths that lead to the River for views at water level. When you've had your fill of Lower Falls, head back up Lewis River Trail. Continue past Trailhead and restrooms. This first part of the trail travels through large campground and is quite busy. There are lots of use paths, but if you stay right, you can't go wrong. Soon you'll climb a small hill to the edge of the campground. There's sign here marking Lewis River Trail. Continue east up hill and head upriver. The trail soon passes quite near FR 90 and you may hear and see cars. After a bit though, the trail drops away from the road and crosses seasonal waterfall on a small Footbridge. The concrete remains of Sheep Bridge are soon visible in the river far below. Next you'll come to a couple of trails coming from the left, first Wright Meadows Trail, second Middle fall Trail. The main Trail used to continue straight at this junction, but landslides resulted in detour. A sign on Middle of Trail directs you to switchback uphill to left to Middle Falls Trailhead. At the parking lot, veer right and pick up Trail few feet away on other side. This trail meanders down, crossing Copper Creek above Copper Creek Falls. The trail continues downhill until Junction. The main Trail goes straight but take switchback downhill to the left to see Middle Falls. The trail beyond there is closed due to a landslide. Back on the main Trail you'll walk about a mile to the base of Upper Falls. There's lot of alder growing up here, but you'll see a steep path that goes to the River bank and allows an unobstructed view of the Falls. The next part of the trail is a steep climb, but the climb is short and the rewards are great. Trail work up side of Alec Creek Canyon, gaining about 150 feet in a quarter mile. Then the trail heads back along the top of Bluff.

Trip Reports

We hiked the full length of the Lewis River Trail from Curly Creek Falls Trailhead to Quartz Creek Trailhead and back over 4 days, three nights. The total length was ~30 miles. The trail was actively being cleared from minor winter blowdown by a couple of volunteers from Evergreen Mountain Bike Alliance. Lower fall Recreation Area parking was closed this weekend, significantly reducing the number of people on the Trail. Mosquitoes were annoyance one of three nights. Overall though, this is a great time to hike this Trail. The forest is overpoweringly green, last dogwoods are blooming, and the waterfalls are full right now!

ELJ Project costs have ranged between 10 000 on the Upper Cowlitz Site to over One-million dollars at other sites. Although not part of sample sites, 7. 2 million dollars was spent on site on the Hoh River system next to highway 101. Responses of these stream channel structural practices have ranged from successful habitat restoration to complete structural loss in attempts to incorporate wood. In the mid-1990s, research on natural log jam characteristics, patterns, and benefits led to technology that is currently referred to as engineer Log jams. Six sites are briefly described as follow. Site 1-Upper Cowlitz River Near Packwood, WA: One of the first Sites for Log jams implemented in January 1996 with new ELJ technology was on the Cowlitz River at River mile 121, three km North of Packwood, WA. These ELJs were designed to treat stream bank erosion and instability and provide salmonid habitat along 430 meters located on private property. Three ELJs instal are no longer there. The drainage area is 260 mi2. Three ELJs were constructed with 200 logs with passive type of anchoring. Primary objectives were stream bank protection and creation of deep pools at each ELJ with associated environmental benefits. Previous to installation, rapid lateral recession into private property occurred due to damage from the fourth highest flood of record: LP III-32 900cfs-25Q. QBKF at USGS Gage Packwood is approximately 9000cfs. Site 1 received post construction flood flows. Floods Qs between 1996 and 2002 ranged from 15 800cfs in 1998 to 30 020cfs in 1996-just five weeks after construction. Two of three ELJs were lost in 1999. The third ELJ was gone in 2002 with the exception of a few large wood members. Landowners estimate loss of 7 acres with 300 feet of lateral recession since construction in 1996. Rc / Wbkf is 1. 9ft / ft. Meander turn with tortuosity values of Rc / Wbkf less than 2. 5ft / ft are susceptible to extreme near-bank share value-tighter meander bend. Figure 3 shows the right bank of Cowlitz several hundred feet behind the 1997 stream bank. Figure 4 is view from right stream bank. Bedload transport and aggradation remain concerns at Site 1. Stream bank stratigraphy is composed of lateral accretion with fine textured soil over vertical accretion-course gravel texture. Sand-size matrix material and finer layers were washed out of gravel strata causing that unit to slough off, which undermine overlying finer textured unit. Overlying finer-textured material has more shear strength. There is a difference in shear strength of finer-textured materials near the top of the bank. See stream bank in Figure 3 behind the blue and white global probe velocity meter. Site 2-Cispus River on USFS Land-Figure 5: Previous to installation, stream bank erosion and lack of salmonid habitat were primary concerns for USFS. USFS Road 23 and USFS Road 28 Bridge crossing at Cispus were at risk. ELJs were constructed at three principle sites refer to, B, and C.
