Salmon struggle with high temps, low levels in Ore. rivers
CORVALLIS, Ore. (AP) — A study of mountain streams in the West over the past 60 years finds the hottest temperatures of summer and the lowest water levels of fall are converging — which is bad news for salmon.
The authors say the convergence gives salmon less time to recover from the stress of warm water before the stress of low water hits — 20 to 30 days less time.
The study was based on stream flow records between 1950 and 2010 from 22 sites in Oregon, Washington, California, Nevada, Montana and Idaho.
Researchers from Oregon State University, the U.S. Forest Service, and the U.S. Geological Survey cited other research indicating climate change is behind the convergence, producing lower snowpacks in winter and earlier snowmelt in spring.
The study appears in the journal Hydrobiologia.

Total BS.. Right now..the coastal streams have enough water flow and cold temps.. This has not hurt the runs..what hurts the runs are the extreme large amounts of sea lions in the estuaries..killing the salmon and steelhead.. just another political hype and agenda that they try and make ya want to believe
 @Whitehawk the article is referencing mountain streams of the west which covers a lot of ground. Oregon has some fine fisheries for being in lower 48. Seal lions are a factor no doubt.  To call the article total BS  and political  is your view.
