HAMILTON, OH (FOX19) - The search resumed Monday for 29-year-old Benjamin Gipson who went missing in the Great Miami River while kayaking Sunday.
Gipson vanished shortly after two kayaks overturned in the river about 3 p.m., according to Fire Captain Brian Ruhl.
Hamilton fire officials are calling the search a "recovery effort."
Witnesses have told authorities the man went under the water when his kayak flipped between the High-Main Street bridge and railroad trestle.
"That's a big span of river, a quarter mile to a third of a mile," Ruhl said Monday.
Two people initially were in the water. 35-year-old Wilbur Strobel was recovered, but Gipson remains missing.
A civilian on a jet ski approached Strobel and retrieved him from his kayak and transported him to the riverbank where fire department units were on scene.
On Monday. crews launched boats into the water and used sonar technology in the search.
"The river is flowing at a higher rate of speed than it normally does, but it is not elevated to the point where you would think there was a current that would be dangerous," Ruhl said.
"The moral of the story is when that river looks still, it is moving at about 2 mph. We took 2 inches of rain on Friday, so it was elevated and had a faster rate of flow."
