(KAIR)--A barge and boat collided Sunday evening in the Missouri River, at Atchison, leaving emergency crews, including the Atchison Fire Department, rushing to the scene, activating the department's rescue boat, as well as one operated by Atchison County Rescue, while other responders dived into the water to search the boat which was found capsized and drifting down the river to the south.

That word is delivered in a release from Atchison Fire Chief Patrick Weishaar, who says it was learned the occupants of the capsized boat had already been rescued by the barge crew and other pleasure boaters on the river.

They were located and brought to shore for evaluation by Atchison County EMS, which resulted in the discovery of no major injuries.

Atchison Police Chief Mike Wilson, in a release, identifies the two Atchison men aboard the small fishing boat as 50-year-old operator, Marvin Reese, and his passenger, 21-year-old Chandler Reese. The elder Reese, Wilson says, was arrested for operating a watercraft while intoxicated, following a Kansas Wildlife and Parks investigation at the scene.

According to Wilson, “witnesses reported seeing the small southbound boat collide with the front of the northbound barge” leading to the accident.

The capsized boat, Weishaar says, "was not able to be secured and was left drifting downriver," with the Coastguard, and other downriver agencies, alerted to the boat's presence.

The barge, identified as The Ava Hadley, of Herman, Missouri, was fully loaded, traveling to Omaha, Nebraska, at the time the collision occurred, just south of the boat ramp, located near Trotter's at the riverfront.

The accident occurred shortly after 7:00 Sunday evening.
