What's New
Overview Curly-leaf pondweed (Potamogeton crispus) is an exotic plant that forms surface mats that interfere with aquatic recreation. The plant usually drops to the lake bottom by early July. Curly-leaf pondweed was the most severe nuisance aquatic plant in the Midwest until Eurasian watermilfoil appeared. It was accidentally introduced along with the common carp. It has been here so long, most people are not aware it is an exotic. References: A Field Guide to Aquatic Exotic Plants and Animals, University of Minnesota Sea Grant Program
