Aquatic Weeds Treatment Schedule

TVA manages aquatic plants in developed public-access areas like boat ramps, swim beaches and courtesy piers on its reservoirs to ensure that everyone can enjoy these public spaces.

The TVA aquatic plant management team works to preserve aquatic plants’ positive qualities, such as providing fish and wildlife habitat, while managing negative impacts.

TVA staff prescribe and assign herbicides based on intensive surveying and monitoring. TVA contractors then apply herbicides at the direction of TVA staff in areas deemed in need of management. Treatment schedules are posted on Thursday for the following week. (Note: Management treatment schedules are contingent upon weather conditions.)

TVA contractor vessels are marked with “TVA Contractor” signs and have a flashing light indicating when an application is taking place. Following treatment, TVA staff then resurvey and monitor each site.
