Workshop planned for managing quagga, zebra mussels

The Bureau of Reclamation plans a Western Invasive Mussel Management Workshop May 5-6 in Las Vegas. Workshop participants will learn how BuRec and its partners have addressed quagga and zebra mussel infestation in the Colorado River and in other western bodies of water. Participants also will be able to apply information from the workshop to their own facilities, BuRec said. Infestations of the mussels are of concern to hydro project owners and operators as the mussels can plug industrial and water intakes and disrupt aquatic food chains by filtering out plankton upon which fish and other organisms feed. (HNN 11/25/08) The workshop will include several presentations. Additionally, panels will address prevention and monitoring, control and mitigation, research, and outreach and education. There is a $90 fee, covering attendance, breakfast, lunch, and snacks. An agenda and registration information are available on the Internet at www.usbr.gov/mussels/workshop/index.html. All registrations must be received by April 24, BuRec said. In addition to the workshop, BuRec plans an operation and maintenance tour of 2,078-MW Hoover Dam on May 4. The tour will provide participants with a behind-the-scenes glimpse of Hoover Dam and show mitigation measures implemented since mussels were first discovered in Lake Mead in 2007. The tour is limited to the first 25 people who sign up. Quagga and zebra mussels arrived in the U.S. from Europe in the 1980s, and spread to many eastern waterways, rivers, and lakes. Quagga mussels were discovered in Hoover Dam's reservoir, Lake Mead, and in Lake Mojave and Lake Havasu, all on the Colorado River, in January 2007.
