Curly-leaved pondweed

Potamogeton crispus

Curly-leaved pondweed (Potamogeton crispus) is an invasive plant of fresh water lakes, ponds, rivers and streams. It is a native of Eurasia and was first detected in mid 1800s.

Tolerant to low light and low temperatures, this plant may become invasive, outcompeting native plants and forming dense mats of vegetation. This plant can be spread from one water body to another via improperly cleaned recreational equipment.
