MANHATTAN, Kan. – The Kansas Department of Wildlife, Parks and Tourism has confirmed the presence of zebra mussels in Tuttle Creek Reservoir. The reservoir encompasses areas in Riley, Pottawatomie and Marshall counties. An alert fisherman found a rock with one adult zebra mussel attached and reported it to KDWPT staff at the Tuttle Creek State Park office. A subsequent search by KDWPT fisheries staff verified the presence of additional zebra mussels. Twenty-nine Kansas lakes are now confirmed to have zebra mussels. Other reservoirs in northeast Kansas with zebra mussel infestations include Milford, Clinton, Perry, Pomona, John Redmond and Melvern lakes.
