This paper describes the change in the macrophyte community caused by dredging a small Wisconsin lake. In water depths up to 1.5 m, revegetation was rapid after dredging. The plant community changed from one dominated by large‐leafed Potamogeton (pondweed), Megalodonta beckii (water marigold), and Elodea canadensis (waterweed) to one dominated by Chara (stonewort), Najas flexilis (naiad), and Myriophyllum (milfoil). Plant growth ended at the 4 m depth and growth recovered much more slowly in water depths between 1.5 and 4 m. The area between 1.5 m and 2.5 m in particular supported a monotypic milfoil stand after dredging.
