Eurasian Watermilfoil (EWM)

Eurasian Watermilfoil (EWM)

Eurasian Watermilfoil (EWM) is one of the Aquatic Invasive Species (AIS) that has invaded Lake Augusta, as well as many of the other lakes in our area and across the state. 

Eurasian watermilfoil is a perennial plant that flowers twice a year, usually in mid-June and late-July. It can grow up to 20 feet tall, but typically only grows three to nine feet tall. It creates canopy-like structures as it grows toward the water’s surface. It primarily establishes through vegetative fragmentation—a fragment can break off, settle in the sediment, grow roots, and establish a new plant.

The plant dies back in the fall, but the root system can survive the winter and begin growing again in the spring.
