In the first trial involving the park's mussel prevention regulations, a federal judge has ordered a Nevada man to pay a $2,500 fine for failing to have his boat inspected for mussels before launching it on Lake Powell.

Laboratories in Colorado are still testing water samples taken from 38 lakes and reservoirs in Utah in 2008.
A small, high-mountain lake in southeastern Utah is the first body of water in Utah to test positive for zebra mussels.
DWR continues work to protect Utah from devastating mussels. Electric Lake, the Colorado River near Moab, Red Fleet Reservoir and Lake Powell are the four waters the DWR has received conflicting results for AIS.
