The invasive species known as zebra mussels have been found in another South Dakota Lake. This time, the mussels were found on a property on Roy Lake.
The mussels were found on a dock as it was being removed from the water. Zebra mussels can devistate the local aquatic ecosystem by consuming algae and plankton which native species need for food.
Once they get in a lake they are almost impossible to get rid of. South Dakota Game Fish and Parks is reminding anglers and lake goers to clean boats after leaving a body of water or entering a new one. This will help prevent mussels from entering other bodies of water. It is the second body of water confirmed to have zebra mussels in Marshall county.
