Federal dam regulators are reevaluating how they conduct dam inspections in the wake of the Oroville Dam spillway crisis, and they’ve ordered the nation’s dam operators to thoroughly inspect their facilities to see “if they have a potential Oroville waiting to happen,” a federal dam inspector said Sunday.
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.
President Trump’s fiscal 2018 budget proposal would cut the Environmental Protection Agency’s Office of Science and Technology nearly in half, while paring by 40 percent funding for E.P.A. employees who oversee and put in place environmental regulations, according to a White House document that was shared with The New York Times.
On a tree-shaded bend in Dutch Bill Creek at Monte Rio, three technicians from the Sonoma County Water Agency huddled on a gravel bar to examine the day’s catch, all in the name of science and a sustained campaign to restore one of California’s most endangered fish. … Nearly half of California’s native salmon, steelhead and trout — 14 out of 31 species — are facing extinction in 50 years under current conditions, according to a scientific study released last week.
That hefty snowpack in the Sierra Nevada is about to start melting more rapidly, setting the stage for spectacular scenery at Yosemite National Park but also raising concerns about public safety from the mountains to the Delta.
Heavy winter snows and a wet spring have filled the Rio Grande River through New Mexico with more water than it has seen in years, and water managers predict the river could stay up well into the summer. That’s good news both for people who rely on the river and for one of the river’s most threatened tiny inhabitants: Hybognathus amarus, a.k.a. the Rio Grande silvery minnow.
Last year, California voters made the state the first in the nation with a ban on single-use plastic bags by approving Proposition 67. The argument that the durable bags were a long-term threat to land and sea carried the day.
Each year we update the itineraries for our annual water tours to provide you with the latest developments in water policy, technology and research. The Bay-Delta Tour, which will be held on June 14 -16, will showcase several new speakers and stories this year. One of the most talked about topics in California water is Gov. Brown’s “twin tunnel” plan, part of the California WaterFix proposal that would build tunnels under the Delta to carry water from north of the Delta to south of the Delta.
We know that California’s aquatic species are at risk from a host of stressors and that drought pushes them closer to the brink. Yet there are significant gaps in our understanding of key factors affecting ecosystem health that make it difficult to effectively manage water for the natural environment. Good practices from other dry places offer lessons for protecting our struggling species and improving conditions in troubled ecosystems.
The California Department of Water Resources (DWR) today [May 19] posted the fifth memo prepared by the independent Board of Consultants (BOC) regarding the spillways at Lake Oroville. Following prior protocol set for the release of all BOC documents, the memo has been released with Critical Energy Infrastructure Information (CEII) redacted.
