L.A. County flood-control officials presented several options for removing built-up debris and mud from a basin above Devil's Gate Dam in northern Pasadena in a draft environmental impact report released Thursday. The basin became choked by mud and debris after the 2009 Station fire and storms that followed. Flood-control officials have warned for years that the build-up compromises the dam's ability to contain another major storm. They say areas downstream from the dam along the Arroyo Seco -- including the Rose Bowl, 110 Freeway and neighborhoods in Pasadena, South Pasadena and the northeastern Los Angeles communities of Highland Park, Hermon, Montecito Heights, Mount Washington and Cypress Park -- could be in danger of flooding.

BONNEVILLE DAM, Wash. - The tiny fish-counting station, with its window onto the Columbia River, was darkened so the migrating salmon would not be spooked. And it was silent - until the shimmering bodies began to flicker by. Then the room erupted with loud clicks, as Janet Dalen's fingers flew across her stumpy keyboard. Tallying the darting specimens, she chanted and chortled, her voice a cross between fish whisperer and aquatic auctioneer. Her body swayed from left to right. Her tightly curled bangs never moved.

Los Angeles funk producer and songwriter Damon "Dam-Funk" Riddick has become one of R&B's most idiosyncratic groove delivery systems, a master of unironic synth joy supremely devoted to '70s and '80s tones. For "Higher," the king of the keyboard has teamed with vocalist/percussionist Steve Arrington, whose work with '70s funk pioneers Slave and as a solo artist inspired some of Dam's jams. The pair have collaborated in the past, but "Higher" marks their first album-length project. The record connects fellow travelers on a journey to the center of a sound, one in which fake hand claps bang alongside synthetic bass tones, layers of falsetto wails roll out lines about making dreams come true ("Blow Your Mind")

Hydroelectric dams may be known as a relatively clean and low-cost energy source, but a new study says that the sediment trapped behind them makes them hot spots for greenhouse gas emissions. A team of European scientists found that methane, which is produced by organic matter in the sediment that collects behind the impoundments, bubbles up through the water and contributes more of the greenhouse gases driving climate change than previously thought. The scientists studied six small dams on the River Saar in Germany and found “hot spot emission zones” of methane, a potent greenhouse gas that is many times more effective at trapping heat than carbon dioxide.

John Wesley Powell, whose legendary descent of the Colorado River in 1869 brought the one-armed explorer fame and celebrity, worried about America's westward migration. The defining characteristic of Western lands was their aridity, he wrote, and settlement of the West would have to respect the limits aridity imposed. He was half right. The subsequent story of the West can indeed be read as an unending duel between society's thirst and the dryness of the land, but in downtown Phoenix, Las Vegas or Los Angeles, you'd hardly know it. By the late 20th century, Western Americans had created a miracle in the desert, successfully conjuring abundance from aridity.

More than 90 years ago the San Clemente Dam rose on what John Steinbeck called in a novel "a lovely little river" that "has everything a river should have. " These days, that's not so true of the Carmel River, which empties into the Pacific Ocean just south of Carmel. The river is overpumped. Flood plain has been lost to development, and the silted-up San Clemente is vulnerable to collapse in an earthquake, threatening 1,500 downstream structures. But next month, in what officials say is the state's largest-ever dam removal, work will begin on a three-year project to dismantle the 106-foot-tall concrete dam and reroute half a mile of the river.
