Water projects necessarily have impacts on fish and other aquatic species. Water, after all, is habitat. So when a new dam or diversion is proposed, we need to find out what fish, frogs and other species will be affected, how many and how significantly. Trouble is, those questions have always been answered based on limited data.
In a state with periodic droughts that are expected to increase in severity, California water suppliers know they must make the most of drinking-water supplies. For some that means increasing conservation; for others, it means developing alternative water sources. San Francisco has done both.
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.”
“They’re less slimy, and certainly less smelly, than a fish carcass would be. But the dry, brown pellets that biologists distributed Tuesday in a backwater channel of Dry Creek may prove to be the vitamin that once-prolific North Coast salmon streams need.”
