The Benton County Noxious Weed Board will be helicopter spraying the Paul Keith Wetland for noxious weeds on Saturday, September 29th. The Paul Keith Wetland Park and associated pathway, from Willowbend to Belmont Blvd., will be closed from 5:00 p.m. Friday to 6:00 a.m. on Monday. The application is being done on Saturday so it does not affect students walking or riding bikes to Libby Middle School.
