Zebra mussels are often found attached to hard surfaces, like rocks, docks, shells, and wood, but can attach to any solid surface, including submerged aquatic plants, native invertebrates, and each other.

They can quickly colonize a lake and make it inhospitable to fish by filtering out all the zooplankton fish eat.  Zebra mussels are very sharp and make the lake difficult to enjoy without protective gear. 

There is no known mitigation for zebra mussels other than preventing them from getting into the lake. WLA has instituted a boat inspection program (see CBCW page), and participates in AIS monitoring.
