Lewis River
Project Overview
PacifiCorp’s 510 megawatt (MW) capacity Lewis River hydroelectric facilities are located in rural southwestern Washington. The first dam site, Merwin, is approximately 10 miles east of Woodland, about 40 miles northeast of Portland, Ore. Constructed between 1931 and 1958, the Lewis River projects are located in a scenic area near Mt. St. Helens in the Cascade mountain range. View fact sheet (PDF).
Click on the construction link above for information on closures.
Springing from Adams Glacier on Mt. Adams, the North Fork of the Lewis River flows past the southern flank of Mt. St. Helens on a 90-mile path before emptying into the Columbia River near Woodland, Wash. Much of the drainage basin of the North Fork of the Lewis River lies within the Gifford Pinchot National Forest and the Mt. St. Helens National Volcanic Monument. Consequently, several state and federal resource agencies are involved in resource management in the project's vicinity.
The sequence of the four Lewis River projects upstream of the confluence of the Lewis and Columbia rivers is: Merwin, Yale, Swift No. 2, and Swift No.1. These four projects are licensed separately by FERC. Merwin (FERC No. 935), Yale (FERC No. 2071), and Swift No. 1 (FERC No. 2111) are owned and operated by PacifiCorp. Swift No. 2 (FERC NO. 2213) is owned by Cowlitz County PUD No. 1 and is operated in coordination with the other projects by PacifiCorp.
Placed in service in 1931, the Merwin project has a generating capacity of 136 mw. The dam associated with this plant is a 313-foot high concrete arch type. It creates Merwin Lake, a 4,040-acre impoundment popular with a wide variety of recreationists.
The Yale project was completed in 1953. It features a 3,780-acre reservoir (locally known as Yale Lake, it also is a popular recreation site) and a main earthfill embankment dam that is 323 feet high. The two turbines in the Yale powerhouse were recently upgraded to a combined rated capacity of 134 mw.
At 240 mw, Swift No. 1 is PacifiCorp’s largest hydroelectric facility. When initially built in 1958, the 512-foot Swift Dam was one of the highest earthfill dams in the world. The Swift Reservoir is 4,600 acres and similarly provides a variety of fishing, camping, swimming and other recreation. The discharge of Swift No. 1 enters a canal that transports the water through the 70 mw Swift No. 2 project owned by Cowlitz County PUD No. 1 before it is returned to the upper end of Yale Reservoir.
PacifiCorp operates several recreational facilities associated with the Lewis River projects. These facilities include 318 camping sites, 268 picnic sites, several boat ramps, swimming beaches, fishing access, and day use areas.

Construction for Lewis River Fish Passage Projects
Overview
Construction work began in April 2011 on new fish passage facilities at the 510-megawatt Lewis River project in Southwest Washington. The new facilities will collect adult fish at Merwin Dam and transport them upstream of Swift Dam where they will be released and can move up the river to spawn. As their young begin migrating to the ocean, they will be collected at Swift Dam by a floating surface collector and transported by truck downstream to a release facility in the lower river. When complete, these projects will open up 117 miles of salmon and steelhead habitat upstream of Swift.
- Merwin Upstream Collection and Transport Facility
-
This project has five main parts:
- Attraction water system
- Fish ladder & hoist
- Holding tank
- Sorting facility
- Truck loading
How does the system work?
Adult fish return to the Lewis River and are attracted to the intake facility by river water coming out at a steady stream, which mimics a natural current and leads the fish away from the working parts of the dam and power house where the fish could be injured.The fish follow this current up a short fish ladder that ends in a trap basket on a hoist that delivers the fish to the holding tank and sorting facility. The fish are sorted based on species, origin (hatchery or wild fish), and point of origin if that can be determined (by tags or fin clips).
Once sorted, fish are loaded onto specially designed trucks that take them to the hatchery or upstream of the dams to be released and allowed to spawn naturally in the stream beds of the Lewis River and its tributaries.
- Swift Reservoir Fish Facility
-
This project has four main parts:
- Floating Surface Collector
- Net system
- Mooring tower
- Access trestle
How does the project work?
Juvenile fish, the offspring of the salmon and steelhead that spawned upstream, will come downstream through the reservoir as they migrate to the ocean.
Given the attraction to downstream current, the juvenile fish will move towards the Floating Surface Collector which re-circulates water to simulate a lake outlet. The net system and the Floating Surface Collector will attract these fish, which are typically 3 - 6 inches long at this stage in life, into a collection area. The fish are collected and gently transported from the facility on specially design trucks via the access trestle. The juvenile fish are then trucked around the dams and released downstream of Merwin to continue their journey to the sea.
The Floating Surface Collector will be located just off the south end of the Swift dam, anchored by the mooring tower and connected to the dam by an access trestle. The mooring tower and access trestle are supported on piles, and the Floating Surface Collector rises and falls with the reservoir level.
Swift Reservoir fish facilty fact sheetHow will this affect me?
The construction for the Swift Reservoir Fish Facility will be staged from Swift Forest Camp and Swift Dam and will result in some disruptions and closures to recreation facilities. Check this webpage for updates on closure information.
Because the Floating Surface Collector is being constructed at Swift Forest Camp, it will need to be floated down the reservior to be installed to the mooring towers. This will be done in the following manner:
- When the reservoir is low in late winter/early spring of 2012, the Floating Surface Collector will be rolled on a specialized dolly system onto on the dry reservoir bed.
- The dolly system will be removed and the Floating Surface Collector will be place on support blocks.
- As the reservoir refills for summer of 2012, the Floating Surface Collector will float and then be towed toward Swift Dam for attachment to the Mooring Tower Structure.
Please continue to check our website for more updates about closures, restrictions, and overall construction progress!
Construction Status
The construction for the Swift Reservoir Fish Facility will be staged from Swift Forest Camp and Swift Dam and will result in some disruptions and closures to recreation activities. Check the links below for updates on closure information.
Swift Dam is now open to pedestrian access.

Public Safety Notification
Safety is a top priority for PacifiCorp. To ensure public safety at our Lewis River recreational facilities, emergency evacuation sirens have been installed at:
- Beaver Bay Campground
- Cougar Campground
- Cresap Bay Campground
The sirens have been installed as a proactive measure to prevent delays in communication in the unlikely event that sudden flooding forces evacuation of these low-lying camping areas along the reservoirs. These sirens are intended to initiate evacuations of the identified recreation areas only and are not intended to communicate evacuation orders to residents nearby.
The sirens will not be used to alert people for other types of emergencies. Although individuals outside the recreation areas may hear the sirens, they are not expected to take any evacuation actions and should instead listen for emergency information from local authorities. Testing periods will occur outside of the normal camping season and will be communicated to nearby residents and property owners in advance.
Any necessary evacuations at other Lewis River recreational areas will be conducted by PacifiCorp staff or local authorities as appropriate.
