“Four or five Friday nights” of work has paid off for Briana Conners, who recently won $10,000 for her winning entry in a contest seeking proposals to get fish past tall dams like Shasta Dam. … While the U.S. Bureau of Reclamation sponsored the contest to solicit ideas for getting fish around tall dams, the agency is specifically interested in finding ways to get young endangered salmon around Shasta Dam.
Before dams were built on the upper Sacramento River, flood water regularly carried woody debris that was an important part of the aquatic habitat. Deprived of this refuge, salmon in the lower parts of the upper Sacramento River have had a difficult time surviving and making it down the river and out to the ocean.
New earthquake sensing stations are being installed in the ground, software is being improved, and operators are being hired to make sure the system is properly staffed, Caltech seismologist Egill Hauksson said at a joint meeting of the Japan Geoscience Union and American Geophysical Union.
Lines of kelp, floating along the waves of the Pacific with help from drone-powered submarines, harvested, processed and turned into biofuel — that’s the vision some researchers and bioenergy company officials are hoping to make a reality. Their goal is still a long way off, but it will start this year with a scaled-down test off the coast of Catalina Island. If successful, growing kelp in the ocean could help resolve the large-scale problem of diverting farmland or crops for biofuel, officials said.
America’s tallest dam was built from earth, stone and concrete – and the towering ambition of Gov. Pat Brown. Sixty years before a crisis at Oroville Dam sent thousands fleeing for their lives in February, the late governor brought an almost evangelical zeal to erecting the structure that would hold back the Feather River to deliver water to the parched southern half of the state.
From The New York Times, in a commentary by David Bornstein:
The Environmental Protection Agency estimates that public water systems lose, on average, one-sixth of their water — mainly from leaks in pipes. The E.P.A. asserts that 75 percent of that water is recoverable.
After three weeks and about 400 miles, I finished my kayaking (and walking) journey down the “most endangered” river in America: California’s San Joaquin. This page collects the tweets from my adventure.
Three weeks and about 400 miles ago, I started a trip down the “most endangered” river in the United States, California’s San Joaquin. The underloved river is born in the Sierra Nevada and snakes across one of the most productive agricultural regions in the world, California’s Central Valley.
Environmentalists who want to bolster endangered coho salmon populations are hoping to launch an initiative to purchase homes along San Geronimo Creek, make them fish-friendly, then return them to market at affordable prices.
From the Las Vegas Review-Journal, in a commentary by David Festa and John Entsminger:
“Today, there is water flowing in the Colorado River Delta — where water has not flowed regularly for half a century — all because water managers, conservation organizations and policymakers in both the United States and Mexico were able to find common ground. …Someone cue music heralding the ‘new era of Western water management.’”
From the California Department of Water Resources (DWR):
“Lieutenant Governor Gavin Newsom brought his technology and institutional change message to the Resources Building Auditorium on Monday, May 12, as a guest of the DWR Enterprise Geographic Information Systems Committee.”
From EPA Connect: The Official Blog of EPA’s Leadership, in a post by Bob Perciasepe:
“The EnviroAtlas combines hundreds of separate data layers developed through a collaboration between EPA researchers and their partners from around the country, including the U.S Geological Survey, the U.S. Forest Service, states, and a number of non-profit organizations and universities.”
“Inventor David Malcolm always believed the low-flow showerhead he created would do well. But even he has been surprised by the boost in business his tiny Coarsegold company — High Sierra Showerheads — has been getting lately.”
