States close river to steelhead retention

By The Columbia Basin Bulletin With an estimated 40 percent decline in the forecasted steelhead run upriver of Bonneville Dam, the states of Oregon and Washington last week closed the mainstem Columbia River to steelhead retention. The states made th...

 

Research shows impacts of melting glacial watersheds

New research shows how accelerated melting of glaciers in the Cascade Mountain Range could dwindle late summer stream flows in decades to come, taking previous work on glacial melt to a new level. A peer-reviewed study is slated for publication in...

 

Opening set for commercial fishermen

Commercial fishing of fall chinook for both Treaty and non-treaty gillnetters opens over the next couple of weeks. The two-state Columbia River Compact at its meeting in Richfield on Aug. 14 approved 9 hours of commercial gillnetting each night...

 

Climate report: 2017 3rd driest year on record

By The Columbia Basin Bulletin It's official: 2017 was the third-warmest year on record for the globe, behind 2016 (first) and 2015, according to the 28th annual State of the Climate report. The...

 

Drought conditions hitting Washington, Oregon

Hot and dry weather has yielded emerging drought conditions across much of Oregon and Washington, but healthy streamflows persist throughout much of the basin mostly due to last winter’s ample snowpack. Oregon Gov. Kate Brown issued a press...

 

Columbia basin spends $450 million on fish & wildlife

A draft report to northwest governors on Columbia Basin Fish and Wildlife Program costs in 2017 was released in early May for review by the public, with the total program costs coming in at $450.4 million, about 18 percent of the Bonneville Power Adm...

 

Steelhead mortality from gillnetting may be lower than thought

New data indicates that gillnetting may not be as harmful to steelhead as previously thought. The ability of commercial gillnetters to fish the mainstem Columbia River has mostly been removed by harvest reforms in Oregon and Washington, citing gillne...

 

Ocean conditions impact fish

The initial period after ocean entry for Columbia River basin juvenile salmon and steelhead is when most of the mortality occurs during their lives at sea, so ocean conditions – temperatures and nutrient supplies – during that period are...

 

NOAA predicts wet, cold La Niña will persist into 2018

Colder and wetter-than-average conditions persisted across the Pacific Northwest in November, with a La Niña weather pattern becoming well established and strengthening during the month, and the outlook is for much of the same going into March....

 

Early fish forecast promising for spring, summer chinook

More spring chinook salmon will be heading upstream to the upper Columbia and Snake rivers in 2018 compared to 2017 returns, according to an early forecast of fish returns by the US v Oregon Technical Advisory Committee. TAC is forecasting a spring...

 

Forecast: Coming La Nina winter will be wetter, snowier

By The Columbia Basin Bulletin A forecast for La Niña conditions in the Pacific Northwest has been raised to an advisory, with colder and wetter weather seen in October now expected to continue throughout the winter. During a Nov. 16...

 

Meteorologists offer predictions for winter

By The Columbia Basin Bulletin Meteorologists at their recent annual winter weather forecast conference came to near agreement on three things: The 2016-17 winter was unusually nasty; weather this coming winter will likely be influenced by a neutral...

 

Change in stream beds impacts salmon spawn

By the Columbia Basin Bulletin A Washington State University researcher has found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. His study is one of the first to quantitatively...

 

Influx of tropical organisms found in Alaska waters

Researchers at NOAA’s Alaska Fisheries Science Center are reporting a never-before-seen phenomenon in Alaska waters—an influx of strange organisms that resemble flattened, translucent sea pickles. It may sound like déjà vu. A similar story made...

 

Change in stream beds impacts salmon spawn

A Washington State University researcher has found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. His study is one of the first to quantitatively show that salmon can influence...

 

Study examines ocean effects on chinook

Productivity of wild chinook salmon from the Columbia River to northern Alaska is subject to large-scale atmospheric and ocean circulation trends, especially the North Pacific Gyre Oscillation, according to a recent study. Other studies of coho,...

 

Warm ocean moves fish north, changes spawning

Unusually warm ocean conditions off the Pacific Northwest in the last few years led anchovies, sardines and hake to begin spawning in Northwest waters much earlier in the year and, for anchovy, longer than biologists have ever recorded before, new...

 

NOAA centers: 55-60% chance of a La Niña winter

NOAA is reporting the summer of 2017 was the third warmest on record globally, with the Pacific Northwest feeling the same heat, but the region may be in for another cold, wet fall and winter. The NOAA Climate Prediction Center’s most recent El...

 

Study looks at juvenile salmon mortality in Columbia's plume

By The Columbia Basin Bulletin As juvenile salmon and steelhead enter the ocean, the common murre and sooty shearwater, offshore avian predators that feed on forage fish such as salmon, throw up a “predator gauntlet” while the fish are still in...

 

NOAA: Ocean surveys show poor conditions for Columbia salmon

Ocean conditions for salmon headed to sea this year are very poor, according to recent NOAA Fisheries research surveys, and have a high likelihood of depressing salmon returns to the Columbia River in the next few years. The outlook is described in...

 

Study indicates salmonids rely on crucial gene

New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published in the journal Science Advances and led by the University of California, Davis. These...

 

Low steelhead numbers restrict gillnetters

Early commercial fall fishing began August 21 for both commercial non-treaty gillnetters and treaty gillnetters on the Columbia River mainstem while Idaho, due to historic low returns, suspended retention of steelhead in Idaho rivers as of August...

 

Steelhead decline starts with ocean entry

West Coast steelhead runs are declining, and a new study pegs much of the problem to poor survival of smolts early after entry into the ocean. After entering the ocean, steelhead smolts head out over the continental shelf from wherever they enter...

 

Fall fishing sees lower coho, chinook returns

Tribes, commercial gillnetters and sports anglers began fishing August 1 as the two-state Columbia River Compact met last week to set fishing times for the fall season. Some 613,840 fall chinook are forecasted to return to the Columbia River, 96...
