Snake River Salmon Scuffle
The wonderful and valuable High Country News has published a very instructive buttal and rebuttal that arise from an article in the print version of the paper that analyzed the long-running struggle over four power dams built on the lower Snake River in the 1960s. Those dams and their reservoirs have long been criticized by scientists and conservationists as inimical to the survival and recovery of once-stupendous salmon runs in the Columbia basin.
(The dams have also been the subject of a long litigation campaign by Earthjustice and its allies, who would like to see the dams removed, or at least breached.)
The Bonneville Power Administration, which operates the dams, has fought vigorously to keep the dams, even arguing in court papers that the structures have been in place so long that they’ve become a permanent, all but natural, fixture in the river, like boulders or eddies.
BPS’s Gregory K. Delwiche wrote a long and fairly sober answer to Ken Olsen’s original piece, that makes good sense—until you read Olsen’s reply. It’s a fascinating exchange, worth taking the time to read. I pretend no particular expertise in this debate, but one of Delwiche’s assertions caught my eye: In response to the claim by Olsen that BPA’s practice is to use all the water in the river for power generation, Delwiche wrote,
The federal agencies operating the hydro system never put "every drop of water" through turbines. It is common practice to spill water around turbines for fish. In 2008, for example, BPA spent $275 million buying replacement power to make up for power not generated at the dams because water was being diverted for fish.
What he didn’t say, and what I know only because of where I work, is that the spilling of water to aid salmon downstream migration came only with a court order, issued by Judge James Redden. Take a look. It’s fascinating stuff.
Meanwhile, Judge Redden has just written to the BPA urging prompt and vigorous efforts to reform river management. One might guess that he’s closer to Olsen than [the BPA guy] in this matter.
