Lake Tahoe One of World's Fastest-Warming Lakes
A first-of-its-kind NASA study is finding nice cool lakes are heating up - even faster than air. Two NASA scientists used satellite data to look at 104 large inland lakes around the world and found that on average they have warmed 2 degrees (1.1 degree Celsius) since 1985...

Successful removal of aquatic invasive weeds in Lake Tahoe
UC Davis Tahoe Environmental Research Center is a partner in an effort to remove approximately one-third of the Eurasian watermilfoil infestation in Lake Tahoe's Emerald Bay, using experimental technologies. The project, which entails covering approximately 8,500 square feet of lake bottom with 8' x 40' reusable bottom barrier strips and hand-removal of the remaining weeds, appears to be an early success...

Good news in annual Lake Tahoe health report
UC Davis researchers noted several bright spots in their annual Lake Tahoe health report, issued today: The 2007 Angora Fire had no significant impact on lake clarity; a small test of a method to kill invasive clams worked; the pollutant phosphorus was at its lowest level in 29 years; and free-floating algae in the lake have generally remained constant since 1996...

Low-Tech Experiment Appears to Be Smothering Lake Tahoe's Clam Invasion
America's most famous alpine lake may have rebounded from historically low water clarity over the last 15 years, but the scientists who look after Lake Tahoe's clear blue waters see no reason to gloat. They've turned their attention to a new foe: an invading clam...

Tahoe clarity linked to environment, economy
Sen. Dianne Feinstein, D-Calif., congratulated fire officials, environmentalists, state and local governments and private efforts for their work to save Lake Tahoe over the past decade. She noted that a UC Davis report released Monday found that while Tahoe's waters may be murkier than in previous decades, they haven't worsened in the past 10 years. The UC Davis study found the lake's waters were clear to an average depth of 68.1 feet in 2009, down from 102.4 feet in 1968, when the school began measurements. She said a goal is to restore Tahoe's clarity to 78 feet over the next 15 years...

University restores Tahoe hatchery, opens second education center
UC Davis last weekend (July 10) opened a second education center at Lake Tahoe to further showcase the university’s environmental research at the majestic Sierra lake. More than 600 people turned out for the grand opening, held in conjunction with Children’s Environmental Science Day. The center is at the old California state fish hatchery just east of Tahoe City, on the lake’s California side...
