Carp study and harvest at Normandale Lake

This summer, the City of Bloomington’s partner, the Nine Mile Creek Watershed District, will study carp movement at Normandale Lake and will use various techniques to remove carp from the lake. If you visit Normandale Lake, you may notice equipment that is part of the carp study and removal efforts. Do not disturb the equipment. 

The work is part of an ongoing adaptive management effort to improve Normandale Lake water quality. Managing the number of carp is part of the overall holistic plan for the lake. Carp are an invasive species. Their bottom-feeding habits disturb the lake bottom, kicking up sediment and releasing nutrients that can fuel algae blooms.
