Migration From Sea-Level Rise Could Reshape Cities Inland

/in /by /UGA Today (Athens, Ga.)by Alan Flurry

When Hurricane Katrina struck Louisiana in 2005, cities inland saw an influx of evacuees escaping the storm and its aftermath. Now, a new University of Georgia study predicts that this could happen again as a result of sea-level rise. In a paper published today in Nature Climate Change, researchers estimate that approximately 13.1 million people could be displaced by rising ocean waters, with Atlanta, Houston and Phoenix as top destinations for those forced to relocate.

Without A Drought, California Takes Stock

/in /by /High Country News (Paonia, Colo.)by Emily Benson

In response to this year’s wet winter weather and effective water conservation, California Gov. Jerry Brown has declared the Golden State’s more than 5-year-long drought over, for the most part. With the exception of four counties, Brown lifted the official drought emergency on April 7. Even as he did so, however, he emphasized the importance of preparing for future droughts — and dealing with the fallout from the one that just ended. “This drought emergency is over, but the next drought could be around the corner,” Brown said in a statement. “Conservation must remain a way of life.”

BLOG: Water Transfers: Crucial to Western Rivers, But State Programs Lacking

/in /by /Water Deeply (New York)by Matt Weiser

Oregon and Washington lead the way in state programs that facilitate environmental water transfers. A new Stanford study concludes Colorado Basin states, including California, have lots of catching up to do. Water transfers are an important way to share a limited resource, especially to help fish and habitats that were historically left with scraps when water rights were parceled out around the West. The water for such transfers usually comes from farmers, who free up water through some kind of conservation measure. By transferring the saved water, a farmer can help imperiled fish and make some money.

State Awards $275 Million Contract For Oroville Dam Repairs

/in /by /The Sacramento Beeby Dale Kasler

Kiewit Corp., a construction giant with extensive experience in dam projects, was awarded the massive repair job at troubled Oroville Dam on Monday. The California Department of Water Resources announced that Kiewit, based in Omaha, Neb., beat two competitors for the job with a $275.4 million bid. Kiewit had the low bid, although its offer was still higher than DWR’s internal estimate that the project would cost $231 million. (DWR said on Saturday that it estimated the project would cost $220 million, but released a corrected estimate Monday.)

Look, You Can’t Do a Ribbon-Cutting on New Plumbing

/in /by /Voice of San Diegoby Ry Rivard

For years, San Diego Unified has known plumbing was aging at 78-year-old Emerson-Bandini Elementary School in Mountain View. In fact, three times in the past 13 years, Emerson’s plumbing needs were held up to voters as one of the reasons they should approve tax hikes to fund school repairs. Voters approved all three measures, pumping billions of dollars into the district. But the plumbing repairs have yet to happen. In the meantime, school officials found alarming levels of toxic chemicals in the water at Emerson.

Serious Design, Construction and Maintenance Defects Doomed Oroville Dam, Report Says

/in /by /Los Angeles Timesby Ralph Vartabedian

Design flaws, construction shortcomings and maintenance errors caused the Oroville Dam spillway to break apart in February, according to an independent analysis by Robert Bea for the Center for Catastrophic Risk Management at UC Berkeley. Bea, a co-founder of the center and retired civil engineering professor, found that in the 1960s, when the dam was being planned, designers did not call for a thick enough concrete spillway floor. Nor did they require the continuous steel reinforcement needed to keep its slabs intact during decades of service.

Lake Powell to Release Above-Average Amount of Water to Lake Mead

/in /by /Las Vegas Sunby Dan Elliott

The federal government said Monday it plans to release an above-average amount of water from a major reservoir in the Southwestern U.S. this year, but it’s less than many hoped after a healthy snow season across much of the West. The Bureau of Reclamation, which manages dams and reservoirs on the Colorado River, said it will release 9 million acre-feet from Lake Powell, sending it down the Colorado into Lake Mead, where it will be tapped by Arizona, California and Nevada. An acre-foot can supply two typical homes for a year.

Water Again Flowing Through Damaged Oroville Spillway

/in /by /Associated Press (As published by Las Vegas Review-Journal)

As construction bids came in to fix the damaged spillway at Oroville Dam, a new round of storms sent water out through the partly collapsed concrete chute over the weekend. State officials expect water to pour through the spillway for up to two weeks, depending on rainfall levels.State officials have reopened the damaged spillway at Oroville Dam as another set of rainstorms began moving across Northern California. Water resumed gushing through the partly collapsed concrete chute Friday morning.
