BOISE, Idaho -- Rallies are taking place across the Northwest to support salmon, which face dire conditions in the Columbia River Basin.

Saturday, the Rally for the River is calling for action from Congress to save endangered fish species in the region, including removing four lower Snake River dams that impede salmon migration and heat up the river.

Brett VandenHeuvel, executive director of Columbia Riverkeeper, said his group recently captured video of the sockeye salmon struggling in the warm waters of the Columbia.

"The heartbreaking video of the sockeye covered in lesions and fungus should sound an alarm," VandenHeuvel asserted. "We need action now from the Northwest delegation."

Water temperatures above 68 degrees can be lethal for salmon, and the Columbia has already been above 70 degrees this year. VandenHeuvel pointed out high temperatures stress salmon metabolism and leave them more susceptible to predation and disease.

He predicted the situation will only get worse unless leaders act to remove the Snake River dams.

Betsy Emery, advocacy and campaign manager for the Association of Northwest Steelheaders, said anglers contribute $5 billion per year to the Pacific Northwest's economy, but she fears salmon in the basin are at a tipping point.

"A lot of us who spend time on the river and spend time thinking about these fisheries are really nervous," Emery remarked. "Could this be that catastrophic event that starts pushing some of these runs that we love so much, from a fishing perspective, into a space where they might not be strong enough to fish?"

VandenHeuvel added people are becoming inspired to take action.

"More and more people are getting involved and recognizing how serious and urgent this issue is," VandenHeuvel contended. "For salmon, for the orcas that depend on them, for the people of the Pacific Northwest."

Rallies are planned for Boise, Corvallis, Eugene, Portland, Seattle and Spokane on Saturday.

The Biden Administration is considering the future of Pacific Northwest salmon and the effect of dams in the region.

The White House Council on Environmental Quality held listening sessions this spring and is now asking for public comments on dams in the Columbia River basin.

They're especially focused on four dams on the lower Snake River that have been major barriers to the dwindling salmon populations that migrate upstream to Idaho.

Mitch Cutter is the salmon and steelhead associate with the Idaho Conservation League.

"What we've seen so far in both the listening session and in the public comments," said Cutter, "is an overwhelming majority of people saying they want to breach the lower Snake River dams - because it's essential for salmon and steelhead, and because there's other ways of doing the things that the dams provide."

Supporters of keeping the dams say they provide essential energy, irrigation and barging functions. But Cutter noted that during listening sessions, more than three-quarters of commenters were in favor of breaching the dams.

The Council on Environmental Quality public comment period is open through August 31.

Cutter said there is interest in removing the dams from a variety of people in the Northwest.

"We're seeing people from across the region," said Cutter, "come out of the woodwork and say, 'This issue matters to me, even if it didn't two, three, five, ten years ago. We'd like to have this problem solved.'"

During this year's legislative session, Washington state lawmakers approved $7.5 million for planning to replace the dam's services. The four Snake River dams are in southeast Washington.

Funding in Washington state's budget is pushing efforts forward to remove four lower Snake River dams in order to save salmon.

Lawmakers committed more than $7 million to begin the transition planning process for the four dams in southeast Washington. The dams have been a site of contention because of their effects on the dwindling population of salmon.

Tanya Riordan, policy and advocacy director for Save Our Wild Salmon, said past studies and reports have called for dam removal, and the federal government sees the new funding efforts as proof the state is ready to take action.

"Although the decision to remove the dams will be made by the federal government -- they're federal dams -- these measures do ensure that Washington state will be prepared to effectively replace the transportation, energy and irrigation infrastructure," Riordan explained.

Last year, Gov. Jay Inslee and Sen. Patty Murray, D-Wash., released a report on replacement of the four dams' services, including barging, hydropower and irrigation provided to nearby agriculture. Riordan believes the new funding measure follows through on their promise. Inslee signed the budget this week.

Erin Farris-Olsen, regional executive director for the National Wildlife Federation, said salmon are resilient and have come back to the Snake River, albeit in smaller numbers. She stressed quick action is necessary to save them.

"We're moving at the pace of our own readiness as humans more so than we're thinking about the ticking of the clock in terms of salmon extinction," Farris-Olsen contended.

Riordan noted more than $26 billion have been spent on mitigation efforts to recover salmon and keep the dams in place, but they have not worked, and she added there are a number of advantages to transitioning away from them.

"We upgrade and modernize our energy system and transportation and irrigation and the state is benefited and communities will be benefited significantly through this process," Riordan asserted. "We'll save salmon, and we will uphold our treaty responsibilities to tribal nations."

Four dams on the lower Snake River have been the sites of contention in the Northwest, and a recent report of an oil spill at one of the dams could be adding fuel to the fire.

The U.S. Army Corps of Engineers reported 300 to 600 gallons of oil leaked from the Little Goose Dam between August and October.

Mitch Cutter, salmon and steelhead associate for the Idaho Conservation League, said there have been similar incidences in recent years of leakage from the lower Snake dams.

"We're seeing the results of these dams being old, frankly," Cutter asserted. "They were started to be constructed in the '60s through the '70s, and I think we're seeing the result of infrastructure starting to outlive its useful life."

There has been a growing chorus of calls to breach the dams to allow for greater passage of endangered salmon and steelhead species in the region. However, there are also opponents of the plan. Rep. Dan Newhouse, R-Wash., recently said there is "no clean-energy future" for the Northwest without these dams.

Cutter is skeptical of Newhouse's analysis, arguing the cost of keeping the dams has become too high to make financial sense anymore.

"They don't provide valuable services to the Northwest system or to the western energy grid," Cutter contended. "They can be easily replaced with other resources that cannot just replace everything these dams do. They would actually improve on the services they provide to the region."

Cutter also stressed it is important to keep iconic species such as salmon and steelhead front and center when discussing this issue.

"There are real solutions for how to replace everything these dams provide, but there's no replacement for wild salmon and steelhead in Idaho or in the Snake River," Cutter added.
