Endangered winter-run chinook expand range, giving hope for species

Record Searchlight – A lot can be discovered by studying the bones in a fish’s ear, including that winter-run chinook salmon — which spawn mainly in the Sacramento River in the Redding area — have been straying farther from home than originally thought. Straying from home may be a good thing in this case. The endangered species' expanding range may give it a better chance at Read More…

By The Numbers:Trapping,Transporting Salmonids In Reintroduction…

The Columbia Basin Bulletin – Portland General Electric biologists are continuing to transport salmon and steelhead adults trapped downstream of the Pelton Round Butte Complex of dams on the Deschutes River and transporting them up into Lake Billy Chinook in their efforts to reintroduce the fish to blocked areas in the upper Deschutes basin. The utility, along with the Confederated Tribes Read More…

New Underwater Footage From Around Block Island Wind Farm Reveals…

NEPR – The American Wind Energy Association, a wind industry trade group, has released new underwater footage from around the Block Island Wind Farm. The wind turbines act as an artificial reef, attracting a variety of marine life. The footage shows mussels growing on the structures that anchor the wind turbines and fish swimming around them. The association is touting the area as Read More…

Benthic Macroinvertebrates: Nature’s Water Quality Detectives…

Environmental Monitor – Teeming communities of life inhabit the bottoms of nearly all waterways everywhere. Hidden from most observers, whether by lack of access or lack of awareness, these benthic macroinvertebrates form much of the foundation of any aquatic food web and ecosystem. However, these tiny denizens of the nation’s waterways are also a mostly captive audience when it comes Read More…

Ninth Circuit Ruling on the Clean Water Act Raises More Questions

News Deeply – It was a great exam question (at least I thought so – you’ll have to ask my Environmental Law and Policy students if they agree): Does the disposal of treated wastewater from a municipal wastewater treatment plant into the ground through injection wells located a short distance from the ocean require a National Pollution Discharge Elimination System (NPDES) permit under the Read More…

Before-and-After Photos of Sierra Show Snow Levels Worse Than During…

KQED – California’s “frozen reservoir” is already melting. With California locked in the embrace of unseasonably dry weather and high temperatures, water content of the Sierra snowpack is currently 22 percent of the long-term average for early February. That’s less than it was on this date in 2015, in the most dismal depths of California’s five-year drought. In these three Read More…

Newly-hatched salmon use geomagnetic field to learn which way is up

Phys Org – Researchers who confirmed in recent years that salmon use the Earth's geomagnetic field to guide their long-distance migrations have found that the fish also use the field for a much simpler and smaller-scale migration: When the young emerge from gravel nests to reach surface waters. The study is published in the journal Biology Letters. The findings have important implications Read More…

How An Alaskan Earthquake Caused Fish to Spawn in Death Valley

The Nature Conservancy – Conservationists are fond of saying that everything is connected, so fond that the idea has become a bit of a cliché. Just how connected is the natural world? Consider this story. Recently, an earthquake off the coast of Alaska caused one of the world’s rarest fish to spawn, thousands of miles away in Death Valley National Park, Nevada. At first glance, the Read More…
