The Schedule of Operations summarizes plant control that FWC contractors and field biologists have proposed to accomplish for the following 1-2 weeks. The schedule shows types of plants and estimated amounts that the contractor plans to control along with control methods for a particular waterbody. Conditions such as rain, high winds, or equipment failures can result in some or all of this planned work not being completed in which case it will be rescheduled for a future date. The Schedule of Operations for a particular period may include several waterbodies. In some instances, more than one contractor may be scheduled to work on the same waterbody but on different plant species, in different areas, or utilizing a different control method.
