A 30-year-old New Jersey man drowned near a family picnic area in Pennsylvania on Tuesday while swimming across the Delaware River, officials said.

The emergency communications center at Delaware Water Gap National Recreation Area received a report of a drowning in the Delaware River near the Kittatinny Point picnic area around 4:10 p.m., the National Park Service (NPS) said.

NPS rangers and dive team members, along with New Jersey State Police and water rescue teams from the Portland, Penn., Volunteer Fire Department responded and quickly recovered the body of a 30-year-old man from the river.

“The man was swimming with family members near the picnic area when he tired while attempting to swim across the river and went under,” NPS said.

The Delaware Water Gap National Recreation Area is known for its tranquil scenery along 40 miles of the longest free-flowing river east of the Mississippi River, according to the NPS website.

The park offers year-round hiking, paddling, fishing and hunting. 

The park service reminded the public to wear a life jacket when swimming, floating, fishing, or boating on the Delaware River.
