Chincoteague to host public presentation on changing inlet and effects on island

The Chincoteague Town Council will host a public presentation later this month focused on how changes to the Chincoteague Inlet are reshaping the island and increasing long-term coastal risks.

The event, titled “An Island Shaped by Its Inlet: The Evolving Threats to Chincoteague,” is scheduled for Thursday, January 15, at 6 p.m. at the Chincoteague Center. The program will feature Dr. Chris Hein of the Virginia Institute of Marine Science and Dr. Ioannis Georgiou of the University of New Orleans, both nationally recognized coastal scientists.

According to Town Manager Mike Tolbert, the most significant change underway is the rapid recession of Toms Cove Hook on Assateague Island, which has caused the inlet to widen dramatically over the past two decades.

Tolbert said the inlet has expanded from roughly a half-mile wide in 2002 to approximately 1.5 miles today. That widening now allows ocean wave energy to directly impact marshes on the south end of Chincoteague, accelerating erosion and increasing water depths near critical infrastructure.

“This is threatening the revetment that protects Mariners Point and the Curtis Merritt Harbor,” Tolbert said, adding that the town estimates it has lost approximately 400 feet of marsh on the south end of the island since 2002.

Town officials say the upcoming presentation is intended to raise awareness of the issue and the need for additional scientific study. Tolbert noted that while Chincoteague submitted a request in 2016 for a formal study by the U.S. Army Corps of Engineers, the project—though approved by Congress—has not yet been funded due to nationwide competition for resources.

In the meantime, Dr. Hein led an independent research effort through VIMS in 2021, with Dr. Georgiou conducting inlet modeling for that study. However, Tolbert said the Corps has indicated it cannot formally rely on that work as part of its own analysis.

He added no long-term solution can be designed until the causes of the inlet’s changes are fully understood. The January 15 presentation will provide residents with an opportunity to hear directly from scientists studying the issue and to better understand how inlet dynamics are affecting Chincoteague’s future.
