California Delta Tunnels Project Hits Snags

The controversial water infrastructure proposal from California Governor Jerry Brown, billed as a solution to the state’s significant water challenges, has hit some snags in recent weeks. “In a landmark vote closely watched across California, Silicon Valley’s largest water agency on Tuesday rejected Gov. Jerry Brown’s $17 billion plan to build two giant tunnels under the Sacramento-San Joaquin River Delta,” the San Jose Mercury News reported.

Inflatable Dams and a Water Wheel: Latest Plan to Revitalize the L.A. River

Hydrologist Mark Hanna stood on the North Broadway Bridge recently and gazed out on an industrial vista of treated urban runoff flowing down the Los Angeles River channel between graffiti-marred concrete banks and train trestles strewn with broken glass. The forlorn scene is in marked contrast to the vision city officials and environmentalists long imagined for the river: Reviving it from a concrete wasteland into a nature center and recreational area.

California’s First Big Winter Snow Storm Headed For Sierra Nevada

It’s only Halloween, but winter is on the way. Two storm systems moving out of the Gulf of Alaska are on track to bring the first substantial snow of the 2017-18 winter season to the Sierra Nevada, starting Friday, and widespread rainfall across the Bay Area over the weekend. Forecasters said Monday that gusty winds and 1 to 2 feet of snow are likely Saturday and Sunday along California’s main mountain passes, including Donner Pass near Lake Tahoe, Tioga Pass at Yosemite, Ebbetts Pass and Carson Pass, with perhaps a foot along the shoreline of Lake Tahoe this weekend.

Two Years After California’s Biggest Dam Removal, Fish Rebound

At a time when California was suffering from a record-breaking drought, removing a dam would have seemed counterintuitive. But that’s what happened in 2015 on the Carmel River when the 106ft San Clemente Dam was torn down in the name of public safety and for the benefit of an iconic fish. Now, two years later, scientists are evaluating just how big an impact the dam removal has had on steelhead trout, which are listed as threatened under the Endangered Species Act. So far, the results are promising.
