The River Board’s Technical Advisory Council has spent the last few months investigating the incidence of invasive aquatic weed growth in the Hillsborough River. With presentations from Hillsborough County Public works, who contracts with the state to perform aquatic weed control, and the Florida Fish and Wildlife Conservation Commission (FWC), which takes the lead in aquatic weed control in public waterways, much has been learned.

Aquatic weed growth varies throughout the year due to temperature and nutrient availability. Rainfall can affect the latter. Weeds can also collect in “back water” areas such as Lettuce Lake Park, due to the prevailing winds, shallow warm waters, and dead end areas. Chemical control is the primary technique to address problem areas. Mechanical removal is cost prohibitive. Additional information and contacts to report problem areas on the river, can be found on theĀ FWC website.
