PORTLAND, Ore. -- More than two dozen private, federal, state and local entities have signed off on an agreement to bring salmon back to the upper reaches of the Lewis River, a tributary of the Columbia in southeast Washington state.

 

Four private dams on the Lewis have blocked 174 miles of salmon habitat for the last 70 years, but under a new settlement, private dam operators have agreed to provide immediate fish passage to the uppermost reservoir, opening 117 miles of salmon spawning habitat. Eventually, they might add fish passage to two other reservoirs, opening up an additional 57 miles of fish habitat.

 

PacifiCorp owns three of the dams -- Merlin, Yale and Swift No. 1 -- while the Cowlitz Public Utility District owns the fourth -- Swift No. 2. Together, the four dams create three reservoirs on the river, with the Swift reservoir being the farthest upstream.

 

"Each of the Lewis River settlement parties can be proud of this agreement," said Washington Gov. Gary Locke (D). "This will ensure long-term, sustainable benefits for the natural resources of the Lewis River while preserving a needed source of electricity for the customers of PacifiCorp and Cowlitz PUD."

The settlement lays out a complex plan that includes introducing adult coho, chinook and steelhead salmon to the upper reaches of the river to spawn. After a few years their offspring will migrate downstream and PacifiCorp will collect them at Swift Dam, truck them around the dams and deposit them back in the river below the lowermost dam, Merlin. PacifiCorp will do the reverse when the fish return to Merlin as adults.

Initially, reintroduction will only occur in Swift reservoir. The agreement calls for similar systems to be installed at Yale and Merlin reservoirs after 13 and 17 years, respectively, but an alternative plan would allow PacifiCorp to create a $30 million "in-lieu fund" to be used for other fish habitat restoration projects upstream and downstream from the dams.

The plan calls for using wild fish for reintroducing steelhead and hatchery stock for reintroducing coho and chinook. The ultimate aim is to boost wild numbers enough to eliminate hatcheries in the watershed altogether, but the more likely outcome is some continued reliance on hatcheries.

 

PacifiCorp and Cowlitz PUD said they are pleased with the agreement because it balances power needs and environmental restoration. The National Marine Fisheries Service, American Indian tribes and environmental groups also applauded the plan.

"This represents one of the biggest boosts for salmon recovery in the lower Columbia River Basin," said Bob Lohn, Northwest regional director for NMFS.

An analysis by S.P. Cramer & Associates, under contract with PacifiCorp, indicated that under current habitat conditions, opening habitat upstream of Swift Dam would produce around 6,200 returning adult coho, 1,200 spring chinook and 1,400 winter steelhead. If habitat improves, those returns might jump to 10,400 coho, 2,300 chinook and 1,800 steelhead (Land Letter, June 10).

 

The river's chinook and steelhead populations are listed as threatened under the Endangered Species Act, and NMFS recently proposed adding coho to the threatened list.

 

For the agreement to take effect, it would have to be approved by the Federal Energy Regulatory Commission. Both utilities submitted license applications to the agency earlier this year. The licenses are set to expire in April 2006. Many of the stakeholders expect FERC to approve the agreement because it was created under the agency's new alternative relicensing approach, which involves stakeholders throughout the process in an attempt to hasten the relicensing process.

 

The agreement will cost PacifiCorp $290 million and Cowlitz PUD $19 million over the proposed 50-year license term. In addition to providing fish passage for salmon and steelhead, the agreement will benefit bull trout, a native fish listed as threatened under ESA due to blockages in migration corridors and genetic dilution from non-native trout.

The agreement also allocates up to $12 million to protect and enhance wildlife habitat for big game and other species in the Lewis River watershed; provides $20 million to boost recreation at the 14 parks PacifiCorp operates along the reservoirs; and proffers $30,000 to improve flood management by investing in automated notification systems, radio transmitters and telephone hotlines to quickly alert residents along the river of possible floods.

 

In addition to PacifiCorp and Cowlitz PUD, signatories to the agreement include: Cowlitz Indian Tribe, Yakama Nation, Washington Department of Fish and Wildlife, Washington Department of Natural Resources, Washington Interagency Committee for Outdoor Recreation, NMFS, National Park Service, Bureau of Land Management, Fish and Wildlife Service, Forest Service, American Rivers, Trout Unlimited, Fish First, Native Fish Society, and Rocky Mountain Elk Foundation.
