Aquatic Plant Control

Santee Cooper's Biological Services unit is responsible for the identification and control of invasive and nuisance aquatic plants on the lakes.

Non-native and invasive aquatic vegetation like hydrilla, water hyacinth, giant salvinia and crested floating heart can have a detrimental effect on the lakes' ecosystem, which is why Santee Cooper is committed to controlling their spread. Treatments include use of the EPA-approved herbicides and stocking the lake with sterile carp that feed on hydrilla.

Please report nuisance vegetation to Biological Services at 843-761-4078 or 843-761-8000 ext. 4564. Also you can email us at or report online using the form below.
