The Louisiana Department of Wildlife and Fisheries will conduct an aerial herbicide application on Spring Bayou in Avoyelles Parish on Thursday to control aquatic vegetation.

About 300 acres will be treated to control American lotus, which grows as a large floating pad. It now covers the waterbody to the extent that navigation has become difficult, according to a press release. 

The herbicides are approved by the Environmental Protection Agency for aquatic use, and are not harmful to lake ecosystems,  humans or fish, but anglers and boaters are urged to stay clear of treatment areas while the spraying is underway.

No fish consumption advisories will be issued for the treatment areas, the release states.
