11 years of warm water in the Columbia River

I try to pay attention to what’s happening on the Columbia River. And I thought I had a handle on things generally. But I didn’t know that the river has been exceeding the temperature limit under the Clean Water Act for more than a decade. Did you know that? Continue reading →

Flame Retardants And Pesticides Make Lousy Fish Food In The Columbia River

Scientists with the U.S. Geological Survey--lots of scientists--have been studying how contaminants work their way through the food web of the Columbia River. We're talking PCBs, flame retardants, pesticides, toulene--nasty chemicals known as endocrine disrupting compounds. Using a foodweb model, the researchers tested insects, fish that eat the insects, osprey that eat the fish and invertebrates that live in the river's sediments and dine on the leftovers.

Redden: Dam plans are "plagued with uncertainty"

In an opinion issued today, Judge James Redden made a point to burn federal agencies on the weak aspects of their plans to offset the environmental impacts of the Columbia River hydropower system. I wanted to list a few of his most barbed remarks. But as Michael Milstein of Bonneville Power Administration pointed out, the judge left the most essential permissions intact so that the hydro system can continue operating all 14 dams in the Columbia River Basin at least until 2014 and continue to kill some salmon incidentally in the course of operations.

Two reactions to Judge Redden's ruling on dams

The federal agencies that built the rejected dam mitigation plan (National Oceanic and Atmospheric Administration, U.S. Army Corps of Engineers and the Bureau of Reclamation) released a joint statement suggesting Judge Redden's ruling isn't the end of the world. They say they're grateful to have until 2014 to work on a better plan, thought they will be considering an appeal: Continue reading →

Redden remands Columbia River dam plan

In a 24-page opinion released today, Judge James Redden rejected the federal plan for managing Columbia River dams to protect salmon. In the opinion, he called the National Oceanic and Atmospheric Administration's conclusion that the hydropower system will not jeopardize the survival of protected salmon and steelhead "arbitrary and capricious." And he threw in some zingers, too (stay tuned). Continue reading →
