The U.S. Fish and Wildlife Service (FWS) is asking boaters to avoid specific backwater areas of Upper Mississippi River Pools 4, 5, 7 and 8 during upcoming invasive species control efforts.
Beginning the week of June 27, 2022, the Upper Mississippi River National Wildlife and Fish Refuge (Refuge) will be contracting to have the aquatic herbicide Diquat applied to approximately 1,100 acres of Refuge backwaters infested with flowering rush. Flowering rush is an aquatic invasive species first observed in these UMR Pools in 2020, according to FWS.
