PORTLAND, Ore. (AP) — A long-awaited federal report out Friday rejected the idea of removing four hydroelectric dams on a major Pacific Northwest river in a last-ditch effort to save more than a dozen species of threatened or endangered salmon, saying such a dramatic approach would destabilize the power grid, increase overall greenhouse emissions and more than double the risk of regional power outages.

The four dams on the lower Snake River are part of a vast and complex hydroelectric power system operated by the federal government in Washington, Oregon, Idaho and Montana. The massive dams, built in eastern Washington between 1961 and 1975, are at the center of a years-long battle that pits the fate of two iconic Pacific Northwest species — the salmon and the killer whale — against the need for plentiful, carbon-free power for the booming region.

Environmental groups that have pushed for years for the dams to come down immediately blasted the report. The three agencies in charge of overseeing the sprawling hydropower system recommended an alternative that prioritizes a “flex spill” approach — spilling more water over the dams when juvenile salmon are migrating to the ocean — and continuing the transport of young fish around dams using trucks and barges in some cases. Both approaches are already in use, but the report calls for additional studies and other dam improvements.

“Rather than seizing this opportunity to heed the public’s call for working together for a solution that revives salmon populations, the draft plan is built on the same failed approach the courts have rejected time and again,” said Todd True, an attorney for Earthjustice who has represented environmentalists and fishing groups in ongoing litigation over the dams.

“We need a different approach and leadership from elected officials,” he said.

Dam removal opponents, however, called the focus on the Snake River a “deadly distraction” from other efforts to help salmon, and said the report presented a balanced solution that won’t add costs for ratepayers or disrupt the region’s power supply.

Clark Public Utilities, Rep. Herrera Beutler applaud federal report

Neither Clark Public Utilities nor the Port of Vancouver took formal positions on breaching four lower Snake River dams.

Both agencies are watching the ongoing review of hydroelectric operations, including Friday’s release of a draft environmental impact statement.

Clark Public Utilities purchases about 60 percent of its power from the Bonneville Power Administration.

Communications Director Erica Erland said the utility considers hydroelectricity a critical component of the Northwest’s power network, as well as a reliable, affordable and carbon-free energy source.

“The headline this morning, specifically about the continued operation of the lower Snake River dams, was positive news,” Erland said. “That said, it’s a very large report, and I think all utilities are diving into the details, taking a look at the potential implications.”

Ryan Hart, chief external affairs officer for the Port of Vancouver, said the deep-water port tends to be more focused on the lower Columbia River, including maintaining its shipping channel and jetties near the river’s mouth.

Hart wasn’t willing to say if the port considers the draft environmental impact statement’s conclusion about the four Snake River dams to be positive or negative.

“I think everyone is hoping for a scientific-based solution for the river system, one that balances energy production, conservation, navigation and the needs of the people of  this region,” he said.

As environmentalists roundly criticized the report, U.S. Rep. Jaime Herrera Beutler, R-Battle Ground, applauded its release.

“The Columbia River plays such an important role in so many aspects of our lives here in Southwest Washington,” Beutler said in a statement. “This draft environmental impact statement provides a framework to continue producing renewable hydroelectric energy, productive salmon recovery efforts, flood risk management and the reliable transportation of goods for our region.

“This EIS is the result of years of federal scientific review and collaboration with regional, state, local and tribal stakeholders, and I look forward to a final record of decision this fall. Until then, I encourage the public to submit their comments to ensure their voice is heard.”

“Once again, the science has determined that destroying the four Lower Snake River dams would have high environmental and economic costs,” said Todd Myers, environmental director at the Washington Policy Center, a conservative think tank.

Oregon Gov. Kate Brown voiced support for demolishing the Snake River dams in a letter to Washington Gov. Jay Inslee this month.

The 14 federal dams on the Columbia and Snake rivers together produce 40% of the region’s power — enough electricity to power nearly 5 million homes, or eight cities roughly the size of Seattle. They also contain a system of locks that allows cities nearly 500 miles (800 kilometers) inland from the Pacific Ocean access to Asian markets via barges that float down the massive rivers to the sea. Roughly 50 million to 60 million tons of cargo navigate the Snake and Columbia river system each year.

Yet the towering dams have proven disastrous for salmon that struggle to navigate past them on human-made fish ladders as they migrate to and from the Pacific Ocean. Salmon are unique in that they hatch in freshwater streams and then make their way hundreds of miles to the ocean, where they spend years before finding their way back to their natal streams to mate, lay eggs and die.

Snake River sockeye were the first species in the Columbia River Basin listed under the Endangered Species Act in 1991. Now, 13 salmon runs are listed as federally endangered or threatened.

The Columbia River system dams cut off more than half of salmon spawning and rearing habitat, and many wild salmon runs in the region have 2% or less of their historic populations, said Meg Townsend, an attorney for the Center for Biological Diversity.

The Snake River dams have fish ladders, but the salmon can get bottle-necked at the dam before they are swept into the ladder, and many get picked off by birds or other predators, Townsend said. Still more get sucked into the dams’ turbines before they discover the fish ladders and get “churned up in a meat grinder,” she added.

Fish ladders are concrete chutes filled with rushing water that bypass the dams and attempt to mimic the environment a salmon would navigate if it were swimming upstream or downstream in river rapids.

“The science shows that pulling out the four lower Snake River dams is the only way to save Columbia river salmon,” she said.

Scientists also warn that southern resident orcas are starving to death because of a dearth of the chinook salmon that are their primary food source.

The Pacific Northwest population of orcas — also called killer whales — was placed on the endangered species list in 2005. A mother orca that carried her dead baby on her back for 17 days brought international attention in 2018 as their numbers have dwindled to 72 animals.

Opponents of dam removal say they want salmon to flourish, but they aren’t sure breaching four major hydroelectric dams will help — and it could instead damage the regional economy and the stability of the power supply.

Reservoirs behind some of the dams allow the Bonneville Power Administration to even out the more erratic power supply from wind and solar by spilling water to generate electricity on short notice. And a move away from low-cost coal plants in the Pacific Northwest has some worried about what the future could hold for ratepayers if the Snake River dams are removed, said Kurt Miller, of Northwest River Partners, which represents community-owned utilities across Oregon, Washington, Idaho and Montana.

“This is a much, much bigger issue than the Snake River dams. If worldwide salmon populations are doing poorly because of climate change and carbon, does it make sense to tear out 1,000 average megawatts of carbon-free electricity?” he said.

“For so many reasons, it’s bad public policy.”

The report Friday addressed those concerns in its recommendation regarding the dams.

Hydropower generation would decrease by 1,100 average megawatts under average water conditions, and 730 average megawatts under low water conditions, the report said. The risk of a regional power shortages would more than double and the lowest-cost replacement power would be $200 million a year, the report said. Those adjustments would increase the wholesale power rate up to 9.6%, the authors wrote.

U.S. District Judge Michael Simon ordered the U.S. Army Corps of Engineers, the Bureau of Reclamation and the Bonneville Power Administration to revisit the impact of the hydroelectric system in 2016 while overseeing litigation over salmon.

In all, three federal judges have thrown out five plans for the system over the decades after finding they didn’t do enough to protect salmon.

The report Friday is a draft and will be subject to 45 days of public comment. A final report — including the agencies’ final decision — is expected in September.
