COLUMBUS COUNTY, NC (WECT) – Aquatic specialists with SePRO began the first treatment for Hydrilla in Lake Waccamaw Tuesday.
The specialists are spraying an aquatic herbicide called Sonar over about 1,000 acres of the 9,000 acre lake.
The herbicide will sink to the bottom of the water and kill the Hyrilla.
Experts said it could take days or weeks before the Hydrilla starts to die. Specialists said they will continue doing follow up treatments for the next few years.
According to a spokesperson for NC State Parks, of nearly 40 state parks, Lake Waccamaw is in the top two in regards to having the most unique ecosystem.
