Study Details Extensive Impacts Of Chemical Treatment Used To Eliminate Destructive Quagga Mussels In Snake River

A copper-based chemical treatment to rid a portion of the Snake River of invasive quagga mussels – the first to be found in any Columbia Basin stream – destroyed up to 90 percent of water-based macroinvertebrates (bugs), nearly all gastropods (snails and slugs) and most white sturgeon residing near the area where the poison was applied, according to a recent study.

Council Draft Report To Congress Notes ‘Significant Challenges To Salmon, Steelhead Still Reman,’ Declining Stocks, Climate Change

In a draft report, the Northwest Power and Conservation Council says since the Northwest Power Act in 1980 its energy efficiency programs have saved some 8,000 average megawatts, enough to power seven cities the size of Seattle, while saving energy consumers some $5 billion in lower utility bills.

UW Researchers Use Artificial Intelligence Model To Simulate 1000 Years Of Current Climate, Interannual Variability In 12 Hours

So-called “100-year weather events” now seem almost commonplace as floods, storms and fires continue to set new standards for largest, strongest and most destructive. But to categorize weather as a true 100-year event, there must be just a 1% chance of it occurring in any given year. The trouble is that researchers don’t always know whether the weather aligns with the current climate or defies the odds.

Coho Urban Runoff Mortality Syndrome: WSU Research Team Discovers How Tire Chemical 6PPD Kills Coho, Step To Finding Alternative

For years, scientists at Washington State University’s Puyallup Research & Extension Center have been working to untangle a mystery: Why do coho salmon in Puget Sound creeks seem to suffocate after rainstorms — rising to the surface, gaping, and swimming in circles before dying?
