Hyrdilla, Watershed Committee of the Ozarks

Hydrilla, an invasive monster of a plant (see above photo) has been found in the Little Sac, James, and Pomme de Terre watersheds.  This article explains yet another reason that MDC, CU, WCO and partners are working so hard to eradicate it.  It harbors a neurotoxic cyanobacteria that can kill waterfowl directly, and indirectly, eagles.  The Washington Post recently published an article about hydrilla and its affects on water fowl.


In areas of the U.S. where hydrilla is established, it damages ecosystems, water supplies, and hampers recreational opportunities, which causes great expense to local economies and businesses. Hydrilla was first found in Southwest Missouri in 2012.  A landowner in the Pomme de Terre River Watershed contacted The Missouri Department of Conservation for assistance because a plant, which was later identified as hydrilla, had “taken over” his pond. Since then, hydrilla has been found in multiple impoundments, including locations in the Little Sac and James River watersheds.

Eradicating hydrilla from our drinking watersheds is our goal.  A team, led by the Missouri Department of Conservation, and including City Utilities, Greene County, the Army Corps of Engineers, and WCO, cooperates on the eradication effort.  The multifaceted approach includes multi-year chemical treatment of infested water bodies, public education and outreach, inspections, and planning.
