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 its reservoir system.

According to Dr. Brett Hartis, TVA Aquatic Plant Management program manager, 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. “Our goal is to provide access for everyone to our reservoirs through a balanced approach to controlling nuisance aquatic plants,” he says. “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.”

Keeping developed public areas weed-free is a top priority for Hartis. A 2017 University of Tennessee study estimates that recreation on the Tennessee River generates 130,000 jobs and the value of the Tennessee River reservoir system for the region is nearly $12 billion.

“The TVA reservoirs are worth about $1 million on average per shoreline mile,” says Hartis. “There is a lot of pressure on us to manage aquatic plants to balance the revenue and jobs the river brings to local communities.”

Aquatic weed management—when and if it is deemed necessary—will consist of the application of EPA-approved aquatic herbicides in nearshore areas where access is limited. (NOTE: Management treatment schedules are contingent upon weather conditions.)
