Boat Traffic Resumes on Millwood Lake Following Cuban Bulrush Discovery

Boat traffic has resumed in sections of Millwood Lake that were previously affected by the invasive aquatic plant, Cuban bulrush, according to the Arkansas Game and Fish Commission (AGFC) southwest region fisheries office.

Dylan Hann, AGFC district fisheries supervisor in Perrytown, explained that a containment boom has been modified to allow boaters to navigate through while restricting the spread of the plant. This floating barrier, similar to those used for oil spills, is designed to prevent Cuban bulrush from escaping the cove near Millwood State Park.

Hann noted that contractors have treated the affected areas with herbicides twice this month, successfully reducing the presence of Cuban bulrush. However, the plant produces seeds that could lead to new growth next spring, prompting AGFC to collaborate closely with the Millwood Corps of Engineers to manage the situation effectively.

Cuban bulrush can easily overwhelm shallow areas, creating dense mats that obstruct boating and fishing access while displacing beneficial native vegetation. The plant was likely introduced to Millwood Lake via boat trailers or fragments from other water bodies.

To combat the spread of aquatic invasives, the public is encouraged to practice the “Clean, Drain and Dry” method: cleaning boats and equipment after each use, draining all water, and thoroughly drying surfaces. Suspected invasive plants should be reported to local fisheries biologists, with details about the sighting.

The Cuban bulrush was identified by an AGFC biologist during routine bass sampling, highlighting the ongoing need for vigilance against invasive species in Arkansas waters. For reporting, visit www.agfc.com/ans.
