PRVWSD Spraying For Hydrilla

News From The PRVWSD

Herbicide Applications to be conducted 
at the Ross Barnett Reservoir

On September 28 and 29, 2011, herbicide treatments for control of hydrilla will be performed at the Ross Barnett Reservoir.

The treatment will include liquid application of herbicides Reward and Komeen, which are approved by the EPA for aquatic use. The use of these herbicides at the prescribed rate for hydrilla control does little or no damage to the native vegetation species present in the treatment areas.

Boaters may presently notice discoloration of the Native American Lotus throughout the lake; this is typical for this time of year for that species.

Hydrilla is an invasive aquatic plant species that can cause considerable damage to a lake and its ecosystem. When left uncontrolled, some of the most undesirable impacts that hydrilla can cause on a lake are unsuitable habitats for desirable game fish species, limited recreational boating access, and an increased mosquito population.

The planned treatment, which is performed in conjunction to hydrilla surveys performed on the lake by Mississippi State University, will include 11 treatment sites totaling approximately 160 acres. During a recent survey of the lake, a significant hydrilla growth was noted in these areas, and specialists stated that it is imperative that we initiate our treatments as soon as possible. These aquatic weed treatments are necessary to keep hydrilla from becoming a bigger problem on the Barnett Reservoir.
