Acting on a report from an alert angler, the Kansas Department of Wildlife, Parks and Tourism (KDWPT) has confirmed the presence of zebra mussels in Lake Shawnee . Zebra mussels are bean-sized mollusks with striped, sharp-edged, two-part shells. They were found at multiple locations on rocks and on underwater portions of a dock ladder. The discovery brings the total of Kansas lakes infested with zebra mussels to 19 and highlights the need for anglers and boaters to know the dangers of moving water and bait fish between lakes.
“We were notified about the zebra mussels by a conscientious angler who found them on a piece of wood he pulled from the lake,” said Jessica Howell, KDWPT Aquatic Nuisance Species Coordinator. “This is a perfect example of how important it is for the public to be vigilant and report anything they suspect could be an aquatic nuisance species,” she added.
The lake will be added to the list of ANS-designated waters in Kansas , and notices will be posted at various locations around the lake. Other lakes in northeast Kansas with zebra mussel infestations include Perry, Milford and Melvern reservoirs. Like those lakes, Lake Shawnee is safe to use for a variety of recreational activities. Since the sharp-shelled zebra mussels attach to solid objects, visitors should be careful when handling mussel-encrusted objects and when grabbing an underwater object when they can’t see what their hands may be grasping. Visitors should protect their feet when walking on underwater or shoreline rocks, a helpful precaution any time they are outdoors.
There is no known method to rid a lake of zebra mussels. According to Howell, prevention is the best way to avoid spreading ANS. “All lake users should take precautions to prevent the movement of ANS from those waters," she said. “The zebra mussels probably were accidentally carried to the lake from another location in the water from boats or bait buckets.” Anglers and boaters should thoroughly clean, drain and dry their boats and equipment after using any body of water. Regulations require that they drain livewells and bilges and remove drain plugs from all vessels prior to transport from any Kansas water on a public highway. Further, people should not take water away from the lake in bait buckets or for aquariums or any other use. Also, anglers cannot transport live fish from any ANS-designated water.
Zebra mussels are just one of the non-native aquatic species that threaten our waters and native wildlife. Boaters and anglers must remember to follow regulations and precautions that will prevent their spread:
· Clean, drain and dry boats and equipment between uses
· Use wild-caught bait only in the lake or pool where it was caught
· Do not move live fish from waters infested with zebra mussels or other aquatic nuisance species
· Drain livewells and bilges and remove drain plugs from all vessels prior to transport from any Kansas water on a public highway.
