Last year, the TVA found water hyacinth in a slough near Scottsboro. TVA quickly partnered with the State of Alabama, bringing experts from both sides to start addressing the invasive water weed. Water hyacinth is bad news for Guntersville and other great fisheries in the Tennessee Valley. The plant can quickly outcompete other beneficial plants, often creating biological wastelands. Hartis and his team are asking the public to be on the lookout for hyacinth this summer. “If you see a [hyacinth] plant, pull it out of the water immediately and put it in the trash. We don’t want plants to float to a new area and establish a new colony.” If you find a large area of hyacinth, please report it to TVA's Public Land Information Center at (800) 882-5263 (between 8 a.m. and 6 p.m. Eastern).
