WARREN , Pa. — Recreation sites around Kinzua Dam in Warren, Pa., have been re-opened.

The sites, including the visitor’s parking lot, restrooms, picnic area and visitors center, were closed last week in response to what federal officials described as an “ongoing law enforcement issue.”

The U.S. Army Corps of Engineers announced the re-opening earlier this week.

“The Army Corps closed the areas after law enforcement officials informed the agency of an unspecified threat involving Kinzua Dam,” said Jeff Hawk, public affairs officer for the Army Corps’ Pittsburgh district. “The Army Corps takes its commitment to protect public health and safety seriously and will implement appropriate measures when aware of increased risk. This includes actions that involve information security and physical security.

“We appreciate the public’s patience as we’ve managed this issue,” he continued.

Hawk said he could not release additional details about the threat.

The Corps of Engineers encourages reporting any suspicious activity to the project staff or 911. Individuals may also contact the See Something, Say Something Corps Watch Hotline at 866-413-7970.

Hawk previously said the threat did not include the operation or structural integrity of the dam. The downstream viewing platform and downstream boat launch remained open and available for use.

“We don’t want people to worry about something structurally wrong with the dam,” Hawk said. “There’s nothing wrong (with the Dam).”
