Hillsborough has begun a treatment called Sonar Genesis to fight the spread of hydrilla, an invasive water plant found in the Eno River. It’s the same herbicide state officials used with great success against hydrilla in Eno River State Park in 2015 and 2016 in a pilot program. Targeted is a 15-16 mile stretch in Orange and Durham.
Hydrilla creates thick mats that coat the surface of the water, impeding on recreational activities and the health of fish and wildlife. According to Hillsborough Mayor Tom Stevens, the plant’s effects have been palpable.
“When you walk across the river, walk across a bridge you can see it fill up the water,” says Stevens. “It really is a mess.”
The treatment is being used at concentrations well below limits set by the EPA and is not harmful to humans, fish or other wildlife. The N.C. Division of Water Management will oversee the treatments which continue through September.
