The treaty came as a response to a 1948 flood that, Katrina-like, destroyed the small city of Vanport, Ore. Critics say the pact has been a force of destruction for the environment, killing off many endangered species. Thirteen different stocks of Columbia River salmon and steelhead are on the list of threatened and endangered species, while dozens more are extinct.
Indian tribes are particularly unhappy, saying the dams made it impossible for salmon to navigate the river, once home to the largest salmon runs in the world. And they’re upset that they weren’t allowed to participate in the original treaty talks.
“I’m pretty sure the tribes would universally say it’s been pretty bad,” said Paul Lumley, the executive director of the Columbia River Inter-Tribal Fish Commission in Portland and a member of the Yakama Nation in central Washington. “It changed the way the river flowed and impacted salmon passage, and it was just a pretty bad deal for the tribes. And the tribes were completely ignored — that’s a true statement.”
Rachael Paschal Osborn, an attorney with the Center for Environmental Law and Policy in Spokane, said historical records made it clear that planners knew the dams would hurt salmon but decided to proceed anyway.
Congress set the stage for the treaty by passing the Flood Control Act of 1950 two years after the monster 20-day flood hammered Vanport, a city of 18,000 near Portland. The Grand Coulee Dam had been built in Washington state in 1941, but the flood made it clear that the dam wasn’t enough to stop flooding on the wild Columbia. So more dams were built.
With the river already so developed, Osborn said, there’s little choice but to extend the treaty so that the two nations continue to coordinate on how to operate the dams. She said there was plenty of “pre-positioning” going on in the Northwest, with various agencies trying to figure out ways to get more water from the Columbia before any new restrictions take effect. The river is a prime source of water for farmers in Washington.
Osborn said that if environmental issues didn’t receive top billing during the new treaty talks, they should at least receive equal treatment with hydropower and flood control.
“I mean, let’s face it: Flood control is necessarily always going to be a priority under the treaty,” Osborn said.
