Salmon swimming on the Columbia River

 

 

Northwest families and business, through charges on their electric bills, have spent nearly $16 billion on fish and wildlife protection and mitigation measures over the past three decades.

These investments have been driven primarily by two powerful laws: the Endangered Species Act (ESA) and the Northwest Power Act (NWP). The ESA requires that nay federal action, such as dam operations, cannot further jeopardize the 13 listed salmon species and must allow an opportunity for recovery. The NWP also requires the impacts of the federal damns on fish and wildlife to be mitigated.

Salmon restoration efforts and costs have grown dramatically over time. Northwest electricity customers are now paying for habitat restoration, hatcheries and to provide mitigation for the salmon harvest, in addition to hydropower and dam improvements. Today, for every $100 that a family or business pays toward their monthly electric bill, $15 to $20 goes towards salmon restoration efforts.

Collaboration among federal and state agency leaders, tribes and other river users has helped boost the number of salmon that are successfully navigating past the dams on their journey downriver to the ocean, and on their return trip back to their native Northwest rivers and streams. Northwest citizens also are doing their part, investing hundreds of millions of dollars every year through their electric bills toward salmon restoration efforts.

These efforts are paying dividends in improving the prospects for many salmon species, including those still listed under the Endangered Species Act.

Safer Passage for Young Salmon


Salmon Survival RateYoung salmon are surviving at the eight large federal dams on the Columbia and Snake rivers at levels generally exceeding the rigorous survival “performance standards” set at each dam. NOAA Fisheries, the federal agency responsible for salmon protection, says these survival levels are akin to juvenile survival rates in free-flowing tributaries and rivers with no dams.

Survival Rates at Dams are High

By the Numbers: Adult Salmon Setting Records

  • In 2015, over 2.3 million adult salmon and steelhead passed Bonneville Dam, only surpassed in 2014 with 2.5 million adults returning, which set a new modern-day record.  Of the fish returning in 2015, the spring, summer, and fall chinook were record or near-record runs.
  • The total 2015 count of Snake River fall chinook passing Lower Granite dam, the furthest in-river of the four lower Snake projects, was nearly 60,000, the second largest run in nearly 7 decades (prior record in 2014).
  • For Snake River fall Chinook specifically, returns of natural origin fish (versus hatchery fish) are increasing. In 2015, the adults returning above Lower Granite laid 9,345 redds (gravel nests), setting a new modern-day record.
  • Snake River sockeye, on the brink of extinction in the 1990s, have been rebuilding. In 2014, more than 2,700 successfully passed the eight mainstem dams on the journey to their spawning grounds—as compared to 1992, when only a single sockeye (known as “Lonesome Larry”) survived the trip. While warm river temperatures in 2015 were detrimental to the run at large, this was a merely a set-back from ever-improving sockeye returns.
