April 21, 2021 By Waterways Journal Beginning April 5, the Minnesota Department of Natural Resources conducted a joint intensive carp-harvesting operation with the Wisconsin Department of Natural Resources to remove invasive Asian carp from Pool 8 of the Mississippi River. Pool 8 extends from Lock and Dam 8, located near Genoa, Wis., upstream to Lock and Dam 7, located near Dresbach, Minn. The effort used the innovative Modified Unified Method (MUM) that combines netting and herding techniques to drive and concentrate invasive carp from a large area of water into a small zone for removal. The two agencies say this is the first time the MUM method has been used in Minnesota or Wisconsin waters, and the first time it has been used anywhere as an early detection and rapid response technique. Other partners include the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service.
