NEW TOOL IDENTIFIES HIGH-PRIORITY DAMS FOR FISH SURVIVAL
Scientists have identified 181 California dams that may need to increase water flows to protect native fish downstream. The screening tool developed by the Center for Watershed Sciences at the University of California, Davis, to select “high-priority” dams may be particularly useful during drought years amid competing demands for water.
“It is unpopular in many circles to talk about providing more water for fish during this drought, but to the extent we care about not driving native fish to extinction, we need a strategy to keep our rivers flowing below dams,” said lead author Ted Grantham, a postdoctoral researcher at UC Davis during the study and currently a research scientist with the U.S. Geological Survey.
“The drought will have a major impact on the aquatic environment.” The study, published Oct. 15 in the journal BioScience, evaluated 753 large dams in California and screened them for evidence of altered water flows and damage to fish. About 25 percent, or 181, were identified as having flows that may be too low to sustain healthy fish populations. READ MORE »
Some folks are predicting mass migration out of California if the drought continues. The U.S. Weather Service, the U.S. Geological Survey and several universities have predicted that the drought may go on for several more years and could last decades. Here is one such prediction (copy and paste into browser) from the Epoch Times website: http://www.theepochtimes.com/n3/1030249-14-california-communities-now-on...
Website visitors: My monthly radio show airs tomorrow at 1 p.m., Sept. 11, 2014, at KFCF, 88.1 FM in Fresno. If you are out of listening range you can listen live streaming on the internet at www.kfcf.org.
My guests will be Venture Capitalist and philanthropist Noel Perry of the organization "Next 10" and Kerman Farmer/environmentalist Walter Shubin. Tune in if you get a chance.
A new study by Cornell University, the University of Arizona, and the US Geological Survey researchers looked at the deep historical record (tree rings, etc.) and the latest climate change models to estimate the likelihood of major droughts in the Southwest over the next century. The results are as soothing as a thick wool sweater on a midsummer desert hike, according to Mother Jones Magazine.
The researchers concluded that odds of a decadelong drought are "at least 80 percent." The chances of a "megadrought" one lasting 35 or more years, stands at somewhere between 20 percent and 50 percent, depending on how severe climate change turns out to be. And the prospects for an "unprecedented 50-year megadrought" — one "worse than anything seen during the last 2000 years" — checks in at a nontrivial 5 to 10 percent.

Attention website visitors: You may have noticed production has dropped off sharply on this website. The reason is I have had some health problems recently coupled with being out of town a lot. However, my radio show, "Down in the Valley" will air tomorrow at 1 p.m. on KFCF 88.1 FM. You can listen live streaming at www.kfcf.org. My guest will be Bakersfield Californian columnist Lois Henry, who writes frequently about water issues in her neck of the woods. Stay tuned.
