Improved returns demonstrate Columbia salmon protection
Among other results in the new report:
- Federal agencies in 2009 restored water to salmon and steelhead streams that otherwise dwindle or run dry at the same time fish are returning to spawn. The 190 cubic feet per second of flow restored to streams in the Columbia River Basin last year exceeds the average amount of water consumed by Portland and nearby cities. The agencies since 2005 have protected and restored stream flows totaling more than three times the average water use of Seattle and Portland combined.
- The agencies fine-tuned spring and summer spill patterns at each dam to best help juvenile fish headed downstream. A video description is available at http://www.youtube.com/watch?v=zS_NGj79y2I
- Efforts to redistribute a large colony of Caspian terns in the Columbia River estuary helped reduce their predation on juvenile salmon and steelhead from about 15 million fish in 1999 to 6.4 million in 2009. However, double-crested cormorant predation on these fish is a growing concern, and agencies are accelerating efforts to address the issue. Together cormorants and terns consumed 17.5 million juvenile salmon and steelhead in 2009, about 15 percent of all those that reached the estuary.
- The agencies in 2009 reopened nearly 265 miles of spawning and other salmon and steelhead habitat that had been blocked by impassible culverts, diversions or other obstacles. Since 2005 the agencies have restored access to a total of 845 miles of habitat.

“Fish are returning in numbers we haven’t seen in decades and to places they haven’t been for decades,” said Lorri Bodi, acting vice president for Environment, Fish and Wildlife at the Bonneville Power Administration. “It’s good evidence of the way states, tribes and federal agencies are working together on behalf of fish and communities.”
The biological opinion specifies performance standards for safe passage of juvenile fish past each federal dam. Tests so far indicate that results are on track to meet those standards through a combination of spill, surface passage improvements that increase the benefits of spill and other actions.
