PHOENIX (AP) -- The Arizona Game and Fish Department says it will be cracking down on boaters starting next year in an effort to stop the spread of quagga mussels and other invasive species.The agency says law enforcement officers with the department will start issuing citations to boaters who don't clean, drain and dry their boats when they leave quagga-infested waters.Since October, Game and Fish officers have been educating boaters at Lake Pleasant and Lake Havasu. They've been distributing literature on the danger of quagga mussels.The mussels can ruin boat motors and clog water intakes, such as pipes and screens on power and water-treatment plants.Citations will be issued starting Jan. 1 to boaters who don't comply with the rules. That means mandatory court appearances and possible fines.© 2013 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
