On the afternoon of May 28th, a 71-year-old Long Island man was reported missing after he fell from his raft while boating on the Upper Delaware River in an area called Butler's Rift. He was not wearing a lifejacket at the time and was seen going under the water by his wife. National Canoe Safety Patrol (NCSP) members were on patrol in the area and immediately notified the NPS and began a hasty search. Park staff responded along with Delaware Water Gap’s dive rescue team and dive teams from the Sparrowbush, Port Jervis, Matamoras and Westfall fire departments. A point last seen was determined and dive operations began. They were hampered by high water and poor visibility and suspended on Saturday, but resumed on Sunday and Monday. No sign of the missing man was found until around 8 p.m. on Sunday evening when dispatch at Delaware Water Gap received a call from boaters reporting a body floating in the river near the Dingmans Ferry Bridge. The body was recovered and found to be that of the missing man. The river had carried it about 25 miles from the point last seen.
