The U.S. Army Corps of Engineers Buffalo District is on a mission to fight hydrilla, an aggressive plant species that has wreaked havoc from Asia to every continent except Antarctica. "Hydrilla completely chokes out our waterways and impacts all the things we enjoy,” said Michael Greer, USACE Buffalo District project manager." It affects water quality, the economy, businesses, hydropower and flood reduction - ultimately our health and our wallets." Buffalo District’s main projects to eradicate hydrilla are at the Erie Canal and Tonawanda Creek, Tonawanda, NY, as well as on Cayuga Lake near Aurora, NY and Ithaca, NY. The District provides assistance on Pymatuning Lake which borders Pennsylvania and Ohio, and at Raystown Lake in south central Pennsylvania. Buffalo District is also lending expertise to a project on the Connecticut River. Funding for the project is available through the Corps of Engineers Aquatic Plant Control Research Program and Great Lakes Restoration Initiative.
