Aquatic Weeds Treatment Schedule

The summer heat is on. That means the Tennessee Valley Authority’s aquatic plant management teams are out on the water surveying public access areas throughout the reservoir system.

TVA manages aquatic plants in developed public-access areas like boat ramps, swim beaches and courtesy piers on its reservoirs on an as-needed basis when recreational use and/or access become seriously hindered. The goal is to provide access for everyone to our reservoirs through a balanced approach to controlling nuisance aquatic plants. We do our best to preserve the positive aspects of aquatic plants, like providing fish and wildlife habitat, while attempting to negate the negative impacts, like hindering recreational use by the public.

TVA’s herbicide applications are prescribed and assigned by TVA staff based on intensive surveying and monitoring. TVA contractors then apply herbicides at the direction of TVA staff in those areas deemed in need of management. In order to better differentiate between privately contracted and TVA-directed management, TVA contractor vessels are marked with “TVA Contractor” signs and have a flashing light to indicate when an application is taking place. Following management, TVA staff then resurveys and monitors each site following treatment. (Note: Management treatment schedules are contingent upon weather conditions.)
