A search is ongoing for a man who fell into the Kenduskeag Stream at the overlook at Valley Avenue and Bruce Road at about 5:30 p.m. on Sunday, according to Bangor police.

Members of the Maine Warden Service, Bangor police and the city’s fire department were continuing their search of the stream about 7:30 p.m., according to Sgt. Wade Betters, spokesman for the Bangor Police Department.

The man, who has not been identified, apparently fell into the stream accidentally after jumping off a wooden platform onto a concrete platform along the Kenduskeag Stream Trail after it passes under Interstate 95.

The National Weather Service over the weekend issued a warning about the cold water temperatures in Maine’s steams, rivers, lakes and beaches. The cold water temperatures can quickly cause hypothermia to anyone immersed in the water.

Betters said that the man went into the stream near some rapids and did not resurface.

“The stream is probably a little bit higher than average due to recent rainfall but it is not excessively high,” he said.

DEEMI Search and Rescue also was on the scene, according to a posting on the Facebook page of the Orono-based nonprofit.
