Aquatic Weed Identification: What’s Growing in My Community’s Pond?

If you’re responsible for overseeing the management of a lake or stormwater pond, you know it’s a valuable asset that elevates the beauty and appeal of your community, golf course, public park, or campus. However, you also know that residents or visitors who expect a well-maintained, picturesque environment will quickly voice their concerns at the first sign of unsightly weeds in the water.

Whether sprouting near the shoreline and shallow waters, floating on the surface, or growing under the water, lake and pond weeds can overwhelm ecosystems and contribute to more serious issues, including muck accumulation, clogged stormwater or irrigation systems, and flooding. Furthermore, weeds may hinder recreation and pose safety risks by clogging boat motors and entangling fishing lines and swimmers.

Even the best-maintained waterbodies are not immune to occasional weed growth. Nuisance and invasive plants can be introduced through boats, recreational equipment, migrating birds, or extreme weather events. The smallest fragment of an aquatic plant can take root and spread quickly, jeopardizing the beauty and health of a lake or pond.

Early detection and swift action are crucial to prevent aquatic weed infestations from escalating into larger, more costly problems.

Identifying aquatic weeds is challenging, as many species closely resemble beneficial native plants and often go unnoticed until they reach disruptive levels. By understanding the four main categories of aquatic weeds, along with their characteristics and regional presence, you can take proactive measures to address potential issues, keep stakeholders happy, and maintain the desirability of your community, course, park, or campus.
