By Brooke Edwards, Daily Press, Victorville, Calif. Jul. 20--SPRING VALLEY LAKE -- Spring Valley Lake is taking precautions to prevent the spread of the damaging quagga mussel, recently found attached to the hull of a boat as close as Big Bear. "It's not an issue now, and that is the reason we started implementing preventative methods," said Osmar Castro, general manager of Spring Valley Lake Association. Quaggas are filter feeders which reproduce quickly and can destroy the natural...

A new study published Wednesday reveals that 57 species carried into the Great Lakes since the lakes were connected to the sea are responsible for $200 million in annual damages. The conservative estimate does not include harm done to other parts of the U.S. or to the Canadian economy, said the report from the Center for Aquatic Conservation at the University of Notre Dame in Indiana. The report said the various species, which includes the round goby and the zebra mussel, have been carried...

A U.S. study suggests invasive species brought in by ocean-going ships may be costing the Great Lakes region more than $200 million a year. A study by the the Center for Aquatic Conservation at the University of Notre Dame and the University of Wyoming said the losses include commercial fishing, sport fishing and the region's water supply. David Lodge, director of the Center for Aquatic Conservation said the $200 million figure is preliminary. The losses are for the U.S. alone, with...

By Ed Dentry It's getting creepier by the minute out there. To the nightmare cauldron of invasive species that have made inroads into the state's waters, we now add quagga mussels. The Colorado Division of Wildlife said Tuesday that biologists have found quagga mussel larvae in Lake Granby. DNA tests performed by the DOW and the Bureau of Reclamation confirmed the invasive mussel's presence. Quagga mussels are slightly larger cousins of zebra mussels, which have spurred a rash of boat...

By David Accomazzo Antero Reservoir will open to boating today after being closed for two months to contain the threat of zebra mussels.Officials will inspect boats on the north ramp only, seven days a week from 6 a.m. to 10 p.m.Workers will decontaminate vessels carrying the mussels, which can clog water-related equipment and cause damage to fisheries by eating beneficial plankton, according to a news release from the Colorado Division of Wildlife.Antero Reservoir has been closed to...

No adult zebra mussels have been found at Lake Powell, but to help keep them out of the popular recreation destination and water supply source, an extra $100,000 is being spent on prevention efforts, the National Park Service recently announced. The money will be used to hire more staff to keep watch at launch ramps, provide educational materials to boaters and to help inspect and decontaminate boats after hours.

WASHINGTON -- Researchers told lawmakers Tuesday that they may have two new weapons against the quagga mussel, an invasive mollusk that clogs municipal water pipes, takes food from native species and may even stimulate the deadly bacteria that cause botulism. The thumbnail-sized mussel has a high reproduction rate and no natural predators, and it's a big and growing worry in the Great Lakes, the Colorado River, Lake Havasu and Lake Mead. More recently, quagga mussels have turned up in...

Central California lakes and waterways are being threatened by tiny mollusk invaders that pose as hitchhikers. Because quagga and zebra mussels are spread primarily through human-related activities, the Department of Fish and Game is asking for cooperation from boaters to prevent these destructive species from gaining a foothold in the San Joaquin Valley. Many other areas of the state have been on high alert since last fall, when quagga mussels were discovered in numerous places along the...

WEST LAFAYETTE, Ind. - Throughout the overlooked depths of Lake Michigan and other Great Lakes, a small but important animal is rapidly disappearing. Until recently, the animal - a shrimplike, energy-dense creature called Diporeia - was a major food source for commercially important species like lake whitefish and many prey fish upon which salmon, trout and walleye rely. Scientists are employing new research methods in a quest to explain their population freefall, which threatens to...

Counting dead birds along Lake Michigan's Upper Peninsula shoreline last November was mind-numbing, even emotional for wildlife biologist Joe Kaplan. Hundreds of loons, cormorants, gulls, long-tailed ducks and grebes were scattered across the sand, washed up and rotting. Then he spotted a familiar bird. The yellow band on its lifeless leg showed it was C3, a loon that had lived for 14 seasons at Seney National Wildlife Refuge in Michigan's Upper Peninsula. The adult male was 22 miles from...
