Columbia Water Levels

Although the latest water flow forecast for the Columbia River calls for less than normal runoff this year, federal officials said Friday they do not anticipate a repeat of last year, when drought and soaring electricity prices led the federal government to sharply reduce salmon-protection measures at Columbia dams.
The Northwest River Forecast Center, an arm of the National Weather Service, released its final March forecast predicting that 97.3 million acre-feet of water will flow through The Dalles Dam this year from January to July. That's 91 percent of normal, and less than the Feb. 1 forecast of 100.1 million acre-feet, but still far more than the 58.2 million acre-feet that passed The Dalles from January to July last year.
The Bonneville Power Administration twice declared a power emergency last year. In response, the U.S. Army Corps of Engineers, which operates the dams, sent only one-fifth of the water it normally diverts over the dams' spillways to help migrating young salmon. Instead, the corps sent the water through the dams' electricity-generating turbines, which can kill or injure young salmon in the spinning blades.
"We're not anticipating any reduction in the spill program this year," said Mike Hansen, a spokesman for the BPA, which markets the electricity the dams generate.
But Bob Heinith, hydrosystem manager for the Columbia River Inter-Tribal Fish Commission, said he worries that the BPA might still declare a power emergency and spill less water than required by the federal salmon-recovery plan.
"There's no water buffer, and BPA doesn't have a financial buffer," Heinith said. "The federal government always hurts fish first when it gets in trouble, and we're afraid it's going to do it again."
