COTTONWOOD FALLS, Kan. - State wildlife officials say an invasive species of mollusk has been found in a Chase County lake.
     The Kansas Department of Wildlife, Parks and Tourism says on its website that adult zebra mussels were found last week at Chase State Fishing Lake located west of Cottonwood Falls.
     Zebra mussels multiply quickly and can create serious problems for water treatment plants and electrical generating plants. Council Grove and Osage City have experienced water shortages because of zebra mussel infestations.
     Zebra mussels aren't native to the U.S., but have spread across the world via shipping and were first found in Kansas in 2003.
     The department says people who use the 109-acre lake need to be aware of new bait regulations designed to prevent the spread of zebra mussels and other aquatic nuisances.
